The Treasure Hunt of the _S-18_

CHAPTER ONE

The Man of Mystery

The high pitched drone of a wasp engine sounded over the municipal

field at Atkinson and Tim Murphy, famous flying reporter of the

Atkinson _News_, poked a grease-smudged face out from behind the

cowling of a trim biplane and squinted skyward. Against the brilliant

sky of the late summer afternoon was the outline of one of the new high

speed transports of the Red Arrow Transcontinental Air Express Company.

The _Day Express_, Chicago to the west coast, was swinging around,

preparatory to landing on the smooth, crushed-rock runway. Tim watched

with appreciative eyes. The new transports, capable of winging their

way from coast to coast at better than three miles a minute, always

fascinated him. He envied the trim, clear-eyed young chaps who sat at

the controls while they in turn would have been willing to exchange

their daily routine for the adventurous news assignments which often

came Tim's way.

The twin motors, mounted in nacelles projecting from the sturdy wing,

idled as the ship drifted downward to touch lightly on the runway and

roll smoothly toward the main hangar.

"Star gazing again?" asked a quiet voice at Tim's elbow.

The flying reporter turned quickly. Carl Hunter, manager of the

airport, was beside him.

"I always get a thrill watching those high speeds come in. There's

something in it that gets into my blood and makes it tingle."

"They're the finest transport planes in the world," nodded Hunter.

"I'd like to fly one of them," mused Tim.

Hunter looked at Tim shrewdly. The flying reporter was slender but his

muscles were like tensed steel. His blue eyes were clear and

unwavering. There was a pleasant twist to his lips but from experience

the field manager knew that they could snap into an uncompromising line

of determination.

"I'll get you a job on the Transcontinental any day you want one," he

said. "Come over to my office and fill out the application blank."

"That would mean leaving the _News_," said Tim. Then, as Hunter grinned

broadly, he added, "I guess the smell of printer's ink is stronger than

the call of the skyways. I'm a reporter first and a flyer second."

"I wouldn't rank either of your abilities ahead of the other. You're

first class at both."

"Thanks, Carl. That reminds me. Have one of the boys finish up this

job. Give all of the plugs a good cleaning. I'd almost forgotten I've

got another column to write for my department in tomorrow's paper."

"I'll make out a work ticket right away."

Tim slipped out of his jumper and followed the field manager toward the

main hangar. The usual crowd of curious people was lined up inside the

ropes to watch the passengers as they disembarked. Tim, always on the

lookout, scanned them as they came down the steps from the plane.

Two attractive girls were first. They looked as though they might be

movie actresses. He'd check the passenger list with the stewardess to

make sure. An actress was always worth a paragraph or two.

The last man to leave the ship drew Tim's attention. There was

something vaguely familiar in the carriage of the head and the set of

the jaw.

The stewardess came by and Tim hailed her. "Who's the tall, well-built

fellow in the gray suit?" he asked.

The girl scanned the passenger list.

"Sorry, I can't tell you. He isn't listed."

"What do you mean by that? Is he traveling on a pass?"

"Hardly. I collected his fare in Chicago and he's getting off here."

"Then you must know his name."

"He didn't give me his name and instructions from the general manager

were to do as he directed so I've listed him on my seat chart as 'Mr.

Seven.' That's the chair he occupied on the trip out."

Tim thanked the stewardess and hurried into Carl Hunter's office.

"Who's the mysterious man who came in on the _Day Express_?"

"He's just as mysterious to me as he is to you," replied the field

chief. "Why don't you ask him what it's all about? I've had a radio

from the general manager to extend him every courtesy and not to ask

questions, but I guess that doesn't cover you."

"Asking questions is one of the things I do best," grinned Tim as he

left the office.

"Mr. Seven" was superintending the unloading of his luggage from the

plane. Three large traveling bags were pulled out of the baggage

compartment and Tim whistled as he thought of the excess fees which

must have been paid for the transport of the heavy bags by air.

When "Mr. Seven" had made sure that his baggage was in proper order,

Tim stepped up.

"I'm Tim Murphy of the Atkinson _News_," he said. "Your face seems

vaguely familiar but I can't place your name. Since you are stopping

here, I'd like very much to have a story."

"Sorry, Murphy, but there's nothing I can tell you. I prefer not to

talk to reporters."

Tim was undaunted. "Do you plan on staying long in Atkinson?"

"That's another question I decline to answer." The muscles around the

stranger's jaw were tightening and Tim sensed stormy weather ahead.

Normally he would have let the whole matter drop but there was

something so definitely perplexing in the other man's attitude that he

persisted in his questioning.

"You must have some special mission here," said Tim.

"I told you before that I wouldn't talk. You can fire away with

questions all the rest of the afternoon and you'll get the same

result--zero. Now if you'll be good enough to suggest your best hotel,

I'll be on my way up town."

Tim named the city's leading hotel. "I'll be glad to take you there in

one of the _News_' cars," he added.

"Thanks, but I'd have to parry too many of your questions."

"It's a draw so far," smiled Tim, "but I'll bet I know your name before

another 24 hours, 'Mr. Seven.'"

"Why call me 'Mr. Seven?'"

"That's what the stewardess did. You were in chair seven coming out

from Chicago."

"It's as good a name as any other."

"Except your real one," interjected Tim.

"Mr. Seven" bundled his bags into a taxi and whirled away toward the

city while Tim stood on the ramp and gazed after the car.

"That fellow's face is familiar," he muttered half aloud, "and I'm

going to dig into our files at the office until I find his picture.

Unless my hunch is way wrong, there must be a big story connected with

him."

Tim's hunches were notoriously right and just how correct this one was,

even Tim would never have dared dream.

CHAPTER TWO

A Secret Service Case

When Tim reached the _News_ office he found a note rolled into his

typewriter asking him to see the managing editor. He crossed the large

news room and knocked at the glass-panelled door which bore the printed

words, "George Carson, Managing Editor."

"Come in," boomed a voice from behind the door and Tim stepped into the

office. "You wanted to see me?"

"Sit down, Tim," smiled the sandy-haired editor who guided the

destinies of the _News_. He motioned toward a chair.

"I've had some correspondence with Ace McDowell of the High Flyers, a

flying circus that is rated one of the best in the country. He wants to

bring his show in here this week-end under the auspices of the _News_.

What do you think about it?"

"I've never met Ace or any of his fliers," replied Tim, "but they have

the reputation of putting on a good air show."

"It struck me as rather a good idea," went on the managing editor. "We

could give the show a lot of space in the _News_ and it would help

popularize the airport. Some people are kicking about the taxes they

have to pay to help support the field. Do you think you could arrange

things with Carl Hunter so the show can come in Saturday afternoon and

put on their stunts Sunday? Of course they'll be carrying passengers

between stunt flights."

"I'll call Hunter at once," promised Tim.

He left the managing editor's office and placed the call from one of

the telephones in the editorial room.

"I've no objections to the High Flyers," the airport manager said, "but

they'll have to pay the field the usual percentage for taking up

passengers."

"I'll put that in the contract," promised Tim. "Keep this under your

hat for I wouldn't want the _Advance_ to print the story of our own air

show first."

"I'll forget all about it until I read your story tomorrow," promised

Hunter.

Tim returned to the managing editor's office.

"Hunter has no objections but the High Flyers must pay the field

fifteen per cent of all the money they take in on passenger rides.

That's the customary percentage for barnstormers."

The managing editor had the contract from the High Flyers on his desk

and Tim, at his suggestion, filled out the blank.

"I'll telegraph McDowell that we will expect them to land here

Saturday," said Carson. "They're over at Charleston this week."

"You might ask him to send on any pictures of the flyers and planes

that are available," suggested Tim.

When Tim left the managing editor's office he knew he was in for a busy

week. There would be stories every day about the flying circus and then

the problems of parking and policing the airport, for a huge crowd

would be on hand to see the stunt flying.

"Get the Jupiter all tuned up?" asked someone behind him.

Tim turned to face Ralph Graves, another _News_ reporter who had been

his flying companion on many an adventure. Two years before when news

had been breaking fast on the skyways, Tim had trained Ralph in flying

and the other reporter now held a transport license. They were bosom

companions and their managing editor counted on them coming in with any

story to which they were assigned.

"I didn't get all of the plugs cleaned," said Tim, "so I'm having the

boys at the field finish the job."

"What's on Carson's mind?" asked Ralph, jerking a thumb toward the

managing editor's door.

"He's just contracted to sponsor the appearance here of Ace McDowell

and the High Flyers. They'll be in Saturday and put on their stunts

Sunday afternoon."

"Which means plenty of work for us," commented Ralph.

"It will mean plenty of work but it will have everyone talking about

the _News_ being alive and wide awake and that's what we want. The

_Advance_ is slipping every day and some morning this fall I wouldn't

be surprised if we wake up and find that our rival paper has folded up

and, like the Arabs, silently stolen away."

"That won't hurt my feelings a bit," said Ralph. "The fellows on the

_Advance_ have made it mighty tough for us these last few months. They

lie, cheat and steal to get their stories and I've run into some actual

bribery."

"So have I, but it won't win for them in the long run. I'm glad we're

working for a paper and an editor that's clean from top to bottom."

Returning to his desk, Tim rummaged through the drawers until he found

an aviation magazine which contained an illustrated sketch of Ace

McDowell and his flying circus. McDowell was short and swarthy with

eyes that were a little too close together to suit Tim. But the _News_

reporter knew that the head of the flying circus was a real flyer and

would put on a good show. There was no sense in building up a prejudice

just from a picture.

Tim rolled a sheet of copy paper into his typewriter and after a

moment's thought on the wording of his opening sentence, started

hammering out the story announcing the coming of the flying circus. By

the use of plenty of adjectives he contrived to write a full column

and, after reading over the story and correcting one or two minor

errors, he laid it on the copy desk.

Dan Watkins, veteran head of the desk, looked up from beneath his green

eye-shade.

"Good story?" he asked.

"One of the best you'll ever read when it comes to writing a lot from a

little," grinned Tim. "As a matter of fact, Dan, we're promoting an air

circus next Sunday and I have a hunch that Mr. Carson will want a full

page headline on one of the inside pages tomorrow."

The chief copyreader scanned the story with practiced eye.

"I should say your hunch is correct. I'll mark it for an inside banner

right now."

The chief copyreader was the only one at the large desk and Tim sat

down on the edge of the horseshoe-shaped work table.

"I wish you had been at the airport this afternoon," he said. "You've

an uncanny memory for faces and names and it would have come in handy."

"See someone you couldn't place?"

"There's something vaguely familiar about him. I've seen his picture

some place and I've a hunch there's a mighty good story connected with

his coming to Atkinson."

"You can always ask them questions," grinned Dan.

"I asked plenty of questions and didn't get a thing."

"Wouldn't he talk?"

"He talked but he didn't say anything. I tried the stewardess and also

Carl Hunter but both of them had received instructions from the general

manager of the line in Chicago to extend this man every courtesy and do

as he directed. The stewardess had him down as 'Mr. Seven' because he

occupied chair seven coming out. When I tackled him about that he said

that 'Mr. Seven' was a good enough name. I couldn't make a dent in him.

He's smooth as silk and as hard as steel."

"What are you going to do about it?"

"I don't know exactly. I'll try to keep tab on him at the Ransom House

where he is staying but with this flying circus coming to town I won't

have much extra time. I'm going to dig into the files and see what I

can find there. I'm positive I've seen his picture in the last year."

"I'll trail along over to the hotel with you if you'd like. Maybe I

could identify him. I've got one of those card index memories."

"I thought maybe you'd help me out, Dan. We'll have a try at it after

supper. I'll meet you at the Ransom House."

Tim and Ralph had dinner together down town and Tim told of his meeting

the mysterious "Mr. Seven."

"Sounds like a story to me," chuckled Ralph, "and I'll be way wrong if

you don't dig it out. Guess I'll invite myself in on the party tonight

and trail over to the Ransom House with you."

"Glad to have you. Maybe you'll be able to identify my mysterious

stranger."

They discussed plans for the flying circus and after leaving the

restaurant proceeded to the city's leading hotel. Dan Watkins was

waiting for them in the lobby.

"I'll see what name he registered under," said Dan. Inquiry at the desk

revealed that the object of Dan's curiosity had registered as Mr. G.

Seven of Chicago.

"He's in the dining room," said Tim when he rejoined his companions.

"We might as well sit down here. He'll have to pass almost directly in

front of us, which will give Dan a good chance to see him."

"If Dan can't identify him, I'll be glad to help you go through the

files," offered Ralph.

"Thanks. With all of the details necessary in arranging for the flying

circus I'll be glad to have a little extra help. Look sharp now. Here

comes our man."

"Mr. Seven" was dressed in the same well-tailored suit he had worn when

he stepped out of the _Day Express_ and into the life of the flying

reporter. He walked slowly from the dining room toward the elevators in

full view of the sharp eyes of the newspapermen. They watched the

elevator doors close and turned to pool the results.

Dan Watkins shook his head.

"I'm afraid I'm of no help. There's something definitely familiar about

the face but I can't place the name. Maybe it will come to me later."

Tim swung around to Ralph. "What about you?"

"I'm just another disappointment and in the same fix as Dan. 'Mr.

Seven's' face is familiar but that's as far as it goes. His name is

among the missing."

"If 'Mr. Seven' will only stay around until this air circus is over

Sunday I'll find out what's behind his mysterious coming to Atkinson,"

said Tim, who felt that "Mr. Seven" had challenged his ability as a

reporter.

On leaving the hotel, they parted, the chief copy reader returning to

his bachelor headquarters and Tim and Ralph going to the _News_

building where they hauled out files of the paper and spread the

heavily-bound books on their desks.

"We'd better check together," suggested Tim. "Then there will be no

chance of our missing a single tip."

For an hour they poured over one volume, scanning each page and

watching with especial care the picture page which was a daily feature.

"I'm too sleepy to go on," said Tim when the city hall clock chimed

eleven times. "Being outdoors most of the afternoon working on the

plane gave me a yen for bed even though I want to keep on digging into

the file. I might go right on over the very picture I'm looking for."

Ralph picked up a telephone and called the Ransom House, where he

ascertained from the clerk on duty that Mr G. Seven had indicated he

would be a guest there for at least a week.

Relaying that information on to Tim, Ralph added, "Now you can go to

bed tonight and sleep soundly."

They had just finished putting away the files when the door of the

editorial room swung open and a stranger walked in. He was middle aged,

with close-cropped, iron-gray hair, piercing blue eyes and large,

capable hands.

"I'm looking for Tim Murphy and Ralph Graves, flying reporters of the

_News_" he said.

"I'm Murphy," said Tim, "and my companion is Ralph Graves."

"Then I'm fortunate to find you together. My card may give you some

idea of what I want."

Tim took the engraved piece of pasteboard and read the following words:

"Henry Prentiss, United States Bureau of Narcotics."

"I'm glad to know you, Mr. Prentiss," said Tim, "but I'm afraid your

card hasn't given me any clue on what you're here for."

"I understand the High Flyers and Ace McDowell are going to put on

their air circus here Sunday under the auspices of the _News_."

"That's correct, but no announcement has been made yet."

"Then you're likely to have two stories for your paper next Monday, the

actual story of the flying circus and the story of the arrest of Ace

McDowell as the head of a notorious ring of dope smugglers."

CHAPTER THREE

The High Flyers

The federal narcotic agent sat down on the edge of Tim's desk and

smiled at the amazed expressions on the faces of the flying reporters.

"Do you mean that you are going to arrest McDowell on a charge of

smuggling dope?" asked Tim.

"I'm going to do my best to take him in custody. He's a slippery

customer but I think we've got all the evidence we need this time."

"What a sensation this will make," whistled Ralph.

Tim was thoughtful. "It's too bad the _News_ is sponsoring the

appearance of the High Flyers if their leader is to be arrested on a

federal charge," he said.

"I'm afraid it's too late to make any changes now," said Mr. Prentiss.

"As a matter of fact, it will make a stronger story for, even though

you are now aware of McDowell's identity, you will go on and help a

federal law enforcement agency to carry out its duty."

"You're right on that point," agreed Tim. "I'm sure that the _News_

will do all in its power to help you."

"I'm wondering why you looked us up," said Ralph. "You could just as

well have waited until Sunday."

"True enough," nodded the narcotics agent, "but I know that both you

and Murphy, as a result of your efforts toward the apprehension of the

Sky Hawk and his gang, were made officers of the state police. I may

need a little official help Sunday and I want men I can trust in an

emergency."

It was a fine compliment to the undaunted courage of the young

newspaper men and it pleased them both. Prentiss had made warm friends

and allies on whom he could count in any emergency.

"McDowell has been smuggling for a long time," went on the federal

agent. "We've been after him for two years but he's a shrewd flyer and

a shrewder smuggler. It wasn't until I got one of my own men into his

outfit that I commenced to get results."

"You've actually got one of your agents flying with McDowell?" asked

Ralph.

"He's rated the next best flyer in the outfit, Tommy Larkin, by name."

"I've heard of him," said Tim, "but I never dreamed he was a federal

agent."

"Neither does McDowell or I'm very much afraid Tommy would be among the

missing."

"Meaning what?" asked Ralph.

"That it would be comparatively easy for McDowell to arrange a crack-up

of Tommy's plane somewhere on a long hop if he ever became suspicious."

"That would be unthinkable," said Tim.

"Not for McDowell. You might as well realize right now that he is ready

to go to any length to save himself from arrest. According to

information from Larkin, McDowell will receive a new shipment of drugs

just before they take off from Charleston on their flight here.

McDowell is to keep it in his ship until they reach Nemaha, their next

stop after they finish their exhibition in Atkinson. That means

McDowell will have the stuff on his ship for at least 24 hours. He

flies a four passenger cabin plane most of the time but for one of the

stunts he goes aloft in a fast two-seater. That's when I'll have a

chance to seize the dope in his cabin ship and take him when he lands."

"Sounds fine if nothing slips," nodded Tim.

"There'll be no slips this time," promised the federal agent.

They discussed plans for the apprehension of McDowell at length and

before he left the office, Prentiss promised to see the managing editor

the next day.

"I'm counting on you two to be with me Sunday," he said before leaving.

"There might be a leak if I called in the local police or even some of

the state troopers at the barracks here."

When the narcotics officer had gone, Ralph wiped his brow and slumped

down in the chair at his own desk.

"Talk about news," he said. "Things never come singly in a newspaper

office. First you bob in with the mysterious Mr. Seven, then we put on

an air show and now we find the head of the air circus is wanted by

Uncle Sam for peddling dope. What next?"

"Learn the identity of 'Mr. Seven,'" grinned Tim.

"You can worry over that one," snorted Ralph. "It's almost midnight

now. I'm going home and I expect I'll have all kinds of nightmares."

"If you suddenly discover the identity of 'Mr. Seven' I'll be glad to

answer the phone even if it is three in the morning," said Tim.

"Just for that, I won't phone you even if I do suddenly open some

hidden recess in my brain and recall who he is." Ralph threw the words

over his shoulder as he left the editorial room.

Tim picked up the aviation magazine which contained the picture of the

High Flyers and looked again at the printed likeness of Ace McDowell.

The eyes were cruel, hard, merciless. Even on the inanimate page there

was something disturbing about them. Next to McDowell was the picture

of Tommy Larkin. He was about the age of Tim or Ralph, stocky and

well-built.

Tim placed the magazine back in one of the drawers, snapped off the

light, and left the office. As Ralph had observed, things never came

singly, and Tim felt a weight of apprehension settling on his shoulders.

The next morning a board of strategy met in the office of the managing

editor. Grouped around the table facing the heads of the _News_ were

the narcotics officer, Tim and Ralph.

"Of course we'll help in every way possible," the managing editor

assured Prentiss. "You can rely upon Tim and Ralph to give you the

utmost assistance and you'll not find their courage wanting in the

pinches."

"That's why I came to them," smiled Prentiss. "I need two men on whom I

can count."

In the rush of plans and details which had to be worked out for the

coming of the High Flyers, Tim was forced to relegate thoughts of "Mr.

Seven" in the far depths of his mind. He managed to drop in at the

Ransom House once a day to check on the presence of the mysterious

stranger and each time learned that the object of his interest was

still in Atkinson.

The High Flyers arrived late Saturday afternoon, wheeling down out of a

cloudless sky. There were eight ships, three mechanics and two stunt

men. Six of the planes were trim, modern crafts but two of them were

old trainers that should have been on the junk heap long ago. Tim was

surprised to see that type of craft.

By agreement, Prentiss had stayed away from the field for McDowell knew

him by sight.

As soon as the ships had rolled up oh the ramp, Tim stepped out to

greet McDowell. The head of the High Flyers was even shorter and

swarthier than Tim had expected. His hand was cold and limp and Tim

felt a chill run along his spine as the close-set eyes seemed to bore

into him.

"Nice field," commented McDowell. "Hope we have a good crowd."

"We've been giving the show plenty of publicity," said Tim.

"That's good. I'm pulling a new stunt tomorrow afternoon. It's a

head-on collision at 2,000 feet between two planes. That's why I'm

wheeling those ancient trainers along. They'll go up in smoke tomorrow."

"Pretty risky sort of a stunt, isn't it?" asked Ralph.

"Not as much so as it sounds. The pilots will chase each other for a

while and then come on head first. Just before they crash both men will

dive over the side in their chutes."

"Who's going to handle the ships?" asked Tim.

"I'll fly one of them. Tommy Larkin will handle the controls in the

other. By the way, you must meet Larkin. He's a fine flyer."

At the mention of Larkin's name, Tim felt a sickening premonition. It

was the fear that McDowell suspected Larkin of being a federal agent.

It would be so easy for him to crash into Larkin before the scheduled

time.

McDowell called to a flyer who was squirming out of coveralls.

"Tommy," he said, "come over and meet the flying reporters from the

_News_. There isn't enough going on here on the ground, so these

fellows hop around in the clouds hunting stories."

"Glad to know you," grinned Tommy, as he shook hands with Tim and

Ralph. "I've read a lot about you, first getting the Sky Hawk and then

cleaning up the rustlers in the mountains west of here."

"I was in on the pursuit of the Sky Hawk," said Ralph, "but Tim ran

down the rustlers single-handed. He's getting to be quite a sleuth."

Tim saw McDowell's eyes narrow and he felt them boring into him. He

changed the trend of the conversation at once.

"We brought several cars from the _News_ down," he said. "Let's get out

your baggage and we'll be glad to take you uptown."

By pre-arrangement, Ralph stepped over to help McDowell while Tim went

with Tommy Larkin. They reached into the baggage compartment of

Larkin's monoplane and Tim whispered, "Prentiss is in town. He got your

message and everything's set for tomorrow afternoon."

"Tell him the stuff is in McDowell's ship in a special compartment

under the floor. Be careful. I've a feeling that McDowell doesn't trust

me."

"Then don't risk your life by going up tomorrow in one of those old

trainers and staging that crazy stunt."

"I'll keep a sharp lookout. McDowell will never be able to crash me

before I jump. Better not say anything more or try to talk to me. It

might arouse suspicion."

Tim nodded and picked up the large suitcase. Together they walked

across the ramp and joined Ralph and McDowell.

They left the flyers at the Ransom House and Tim caught a glimpse of

"Mr. Seven" in the lobby. As soon as the flying circus was out of town

he'd get on the trail of "Mr. Seven" again and see if he couldn't learn

his real identity. There was a story there if he could dig it out.

Sunday, the day of the big air show, dawned clear and windless, ideal

for the stunt flying and just warm enough to insure the attendance of a

large crowd. The first stunts were scheduled for ten o'clock and half

an hour before Ace McDowell went aloft to do an outside loop there were

more than a thousand cars parked in the roped off spaces around the

field with more arriving every minute. Tim's plans for handling the big

crowd were working out smoothly and he felt some of the tension

slipping from his shoulders.

At an early morning conference in the _News_ office with Tommy Larkin

and his chief, it had been decided to arrest McDowell when he floated

down in his chute after the plane crash. In the meantime, Prentiss

would seize the dope in the flyer's plane and they would spring the net

from which there would be no escape for McDowell. Tim and Ralph were

content to be on the sidelines for they knew the danger in crossing a

man like McDowell.

The other flyers in the circus were quiet, competent chaps, most of

them under thirty and, as far as the narcotics agent could learn, had

no connection with McDowell's smuggling activities. The show started

with McDowell's stunt flight, which left the crowd gasping and

speechless but not so paralyzed but what as a large number rushed for

the ticket sellers and bought rides in the other planes. The next stunt

program was at one o'clock with Tommy Larkin going aloft with one of

the wing walkers, who capered all over the ship in a series of

sensational stunts.

By early afternoon the crowd had increased to such an extent that the

special police estimated more than 15,000 were watching the air show;

and the passenger planes were running to capacity on every flight.

Prentiss, who had arrived at the field, was remaining out of sight in

Carl Hunter's office and once, when McDowell entered, was forced to

make a hasty retreat into the washroom.

The loudspeakers were blaring with the announcement of the next stunt

flight, the crash of the two planes in mid-air. Tim heard the words

vaguely.

"The greatest air thriller ever performed," the announcer was informing

the crowd. "Two costly airplanes, speeding at more than 100 miles an

hour, will positively crash head-on at an altitude of 2,000 feet. It's

daring, death-defying, breath-taking in its thrills. You'll be glued to

your seats when you see these ships hurl towards each other piloted by

Ace McDowell and Tommy Larkin, two of the foremost flyers in the

nation. They'll go aloft in fifteen minutes. In the meantime, there's

time for one more ride in the passenger planes. Let's go, folks."

The old trainers had been kept in the hangars where a field crew had

given them a hasty coat of paint that morning. They glistened bravely

in their new dress and the motors, which were turning over slowly,

sounded sweet.

Tim inspected the ship that Tommy was to fly. If it held together long

enough to get to 2,000 feet Tommy would be lucky but with a chute on,

he'd be able to get out if anything happened before they straightened

out for the crash.

McDowell's ship was in better condition. It was well rigged and Tim,

squinting under the hood, was surprised to see a big Barko 16-cylinder

motor turning the prop over. The old plane's lines were good. It was

still plenty fast enough to give the average modern ship a good race.

Too bad to sacrifice a sturdy old veteran like that just to appease the

thrill-seekers.

Tim looked around for Ralph, who had gone over to the pilot's room in

the administration building. His companion was nowhere in sight but

McDowell and Tommy, their chute packs banging awkwardly against their

legs, were making their way toward the hangar. McDowell's own monoplane

had been rolled inside.

McDowell was giving Tommy final instructions as they entered the hangar.

"We'll take our time getting up to 2,000," he said. "Then we'll circle

around and make several false rushes at each other. After three or four

times I'll waggle my wings and the next time we'll let them go. We'll

be west of the field where the ships won't do any damage when they

crash. Stick with them as long as you can and then go overboard. Got

that all straight?"

Tommy, a little grim, nodded.

"I'll handle my end of it," he said, climbing into the cockpit of the

ancient trainer.

McDowell, eyes narrowed to slits as hard as steel, looked at the crowd.

"They're going to get a real thrill," he said savagely, smacking his

clenched hands together.

Tim looked at him curiously. McDowell outwardly wasn't nervous yet he

appeared to be laboring under a great strain. Could he suspect Tommy's

real identity? The question burned itself into Tim's mind. If McDowell

was suspicious he might fake the crash and after Tommy went over the

side, roar away in the trainer. That might explain why the old ship had

such a powerful motor.

Tim stepped over to Tommy's ship and climbed up so he could yell into

Tommy's ear.

"I don't like the way McDowell looks," he said. "Be careful."

Tommy nodded.

"I'm not taking any chances this afternoon. The first thing that looks

funny will find me going over the side in the chute."

The loud speakers were blaring. The field was being cleared and the

tension in the crowd increased.

"In the Number one plane," boomed the announcer, "is Ace McDowell. In

the Number two ship is Tommy Larkin. Here they come."

The flyers gunned their motors and the old ships, gleaming under their

coat of hastily applied paint, rolled out on the ramp.

A mighty roar went up from the crowd. The field was finally clear of

the passenger carrying ships. The signalman in the control tower waved

his flag at Tommy. The young flyer opened his throttle, the venerable

craft waggled its wings, felt the call of the skies, and rolled

smoothly down the runway. Tommy took his time in getting off the field.

With as little strain as possible on the ancient wings he lifted his

plane into the air.

The flag waved again and Ace, pushing his throttle ahead hard, flipped

the tail of his ship up and went scooting after the leisurely soaring

Tommy.

The planes climbed in easy circles with Ace going up much faster than

Tommy. They were up a thousand feet when Tim felt a tug at his arm and

turned to face the narcotics inspector. "Give me a hand and we'll see

what we can find in McDowell's plane," said Prentiss. They hastened

into the hangar and climbed into the cabin. Tommy had given them the

exact location of the hidden compartment and without wasting time

Prentiss took an iron bar and smashed his way to it. With eager fingers

he ripped away the splintered wood of the top and delved inside. When

his hands came into view again they held small white containers.

"We've got McDowell with the goods this time," said Prentiss. "When he

comes down I'll arrest him. I'll turn this over to the field manager to

place in his safe while I'm out getting McDowell."

Prentiss turned back to Tim as he started for the administration

building.

"Better come along when I go after McDowell," he said. "I may need some

help. Bring your friend with you."

"I will if I can find him," promised Tim. "He disappeared about half an

hour ago and I haven't seen him since."

A commotion near the pilot's quarters drew his attention just then.

Someone broke away and started running toward him. It was Ralph,

staggering slightly, and holding a blood-stained handkerchief to his

head.

CHAPTER FOUR

The Mad Pursuit

Something was radically wrong and Tim, forgetting for the moment the

drama soon to be enacted in the sky, ran toward Ralph. He caught his

friend in his arms as he stumbled. Blood was flowing freely from a long

gash on the right side of Ralph's head.

Ralph was on the verge of unconsciousness but he made a heroic effort

to speak.

"It's Tommy," he whispered. "McDowell's slashed his chute. If he ever

steps over the side he's gone."

Tim's face whitened at Ralph's alarming words. Tommy's chute slashed!

He glanced aloft. The planes were almost up to 2,000 feet. In a few

more minutes they would be rushing headlong toward each other and Tommy

would step over the side to hurl like a falling star to the ground.

Tim's eyes closed to shut out the image which flashed across his mind.

Prentiss reached his side.

"What's happened?"

"I don't know exactly," said Tim, "but McDowell's slashed Tommy's chute

with a knife. Take care of Ralph. I'm going up to stop Tommy."

"Take him into my office," directed Carl Hunter, who had arrived on the

run and overheard Tim's words.

Prentiss gathered Ralph in his arms and stalked toward the

administration building while Tim and Hunter ran down the ramp.

Tim scanned the field. It would be impossible to get the fast Jupiter

which the _News_ owned or the American Ace which he and Ralph operated

out of their hangars. He turned toward the other planes on the field.

It would take a fast ship to get up there in time to stop the crash of

the two planes. His eyes rested on McDowell's own monoplane. It was

trim and fast and the 300 horsepower motor was capable of pulling it

almost vertically skyward.

"I'll take McDowell's plane," he told Hunter. The field manager gave

him a hand and between them they whipped the ship around and headed it

toward the open field.

Tim climbed inside, stumbled over the smashed boards which had hidden

the secret compartment, and sat down in the pilot's seat. The controls

were slightly different from the ships he had been accustomed to flying

but he knew he could handle the plane without trouble. He glanced at

the gas gauge. The tank was a quarter full.

One of the High Flyers ran toward him, protesting on the use of the

monoplane, but Hunter waved him back with a curt explanation. Tim

turned on the starter and the motor, still warm, caught on the first

turn.

He was about to give the ship the gun when Prentiss ran toward him, a

rifle in hand. The narcotics inspector clambered into the cabin and

slammed the door.

"Let's go," he shouted. Tim nodded and opened the throttle. The field

had been cleared for the stunt and he sped out of the hanger and

rocketed into the air. With the motor taking a full flow of gas, he

shot the speedy monoplane into the air. They danced skyward in a crazy,

climbing turn that saw the earth dropping away from them.

"How's Ralph?" Tim shouted.

"He'll be all right. Got a nasty bump on his head but there's a doctor

patching him up now. He's weak from loss of blood more than anything

else."

Tim, with the stick jammed back between his knees, was watching the

drama of the circling planes. He was careful to keep behind McDowell as

much as possible.

The old trainers had levelled off and were jockeying for the first dash

toward each other. Tim's hands gripped the stick hard as he saw them

start. Then he relaxed a little. Ace hadn't waggled his wings. There

would be no crash this time.

The old ships soared past each other with little room to spare and Tim

almost pulled his own ship higher by the sheer tension he was on.

Tommy was circling slowly for another dash toward Ace when Tim flashed

past him waving frantically. In pantomime he went through the motions

of jumping and then shook his head vigorously while Prentiss attempted

to indicate to Tommy that his chute was damaged.

As he flashed by a second time Tim caught the look of alarm in Tommy's

eyes and saw the other examining the chute pack. There was the sudden

roar of another motor and McDowell, forgotten for the moment, shot down

toward them.

"He's after us!" cried Prentiss.

Without looking Tim sent the monoplane into a tight roll and the wings

of the old trainer almost brushed their landing gear as they flopped

over. A bullet crashed through the bottom of the cabin.

"He's on to us," said Tim grimly, "but we'll keep him busy until Tommy

can land that crate of his."

Tim whipped the monoplane out of the roll. Below him McDowell was hard

after Larkin's plane. It was evident that he was out to destroy the

other flyer if at all possible. He was going at Tommy head-on again.

This time there seemed little doubt but what the ships would crash in

spite of all that Tommy could do to escape the trap. McDowell's plane

was too fast. He met every maneuver of Tommy's and played him one

better.

For the moment he had forgotten Tim in his terrible concentration of

destroying the flyer he felt sure had turned in the evidence which

would lead to his arrest. If he had not forgotten Tim, he had sadly

underrated the flying ability and nerve of the reporter.

With wind screaming past the struts and motor on full, Tim dove

headlong toward McDowell. Some sixth sense must have warned his prey

for McDowell threw a startled glance over his shoulder. Instantly he

changed tactics and left Tommy to make a hurried landing with the old

trainer while he took up the new feud with his unforeseen foe.

Prentiss opened the windows on the right side of the cabin and steadied

the rifle. There was a grim purpose written on the tensed lips. If he

could line his sights on McDowell, the rifle would spit flame and

death. Crouched on the floor of the cabin, finger crooked on the

trigger, cheek resting on the gunstock, he waited for the chance he

felt was sure to come.

Below them the startled thousands watched the deadly duel, craned their

necks as the planes twisted and darted through the air, and at times

seemed almost to crash before one of them flipped this way or that just

in time to avert a catastrophe.

Tim and Prentiss had the advantage of a slightly faster plane but

McDowell had a chute. If they crashed he would have a chance of

escaping while the flying reporter and the narcotics inspector would be

pinned in the falling wreckage of their ship.

McDowell was playing the game for his life. In spite of their danger

Tim thrilled to the masterful flying which it required to escape the

mad rushes of the other.

For half an hour the grim battle went on. Then it ceased as suddenly as

it had started. McDowell, giving his plane a full gun, darted away

southwest. He was making a break for safety. With a heavy bank of

clouds rolling up in the west, night would drop its mantle early. There

was just a chance that he might remain aloft until he could find

shelter in the darkness. Tim saw through McDowell's strategy at once.

Undoubtedly the other had a full tank of gas and since the old trainers

usually had large tanks, sufficient to keep the ancient craft aloft

until after nightfall. The flying reporter glanced again at the gauge

on the instrument board of the monoplane. He didn't need to. He knew

what the needle indicated without looking but perhaps there had been

some mistake.

The gauge showed only an eighth of a tank of gas. Another half hour in

the air; perhaps a little more. Then they would be forced down and

McDowell would wing on alone.

Tom leaned back and shouted to the inspector.

"We've got only enough gas for another half hour. Want to land now,

fill up the tank, and then try to overtake McDowell, or keep after him

until our fuel gives out?"

"Something might happen to his ship before our gas gives out. We'll

keep going as long as we can," Prentiss shouted back.

Tim nodded and set out in full pursuit. In three minutes he was on

McDowell's tail and he throttled down. No use to push the motor any

harder than necessary.

The minutes droned on. Tim checked their direction. It was obvious that

McDowell was heading for the border. It was a long hop; impossible in

one jump, and he wondered where the pilot ahead of him intended to

refuel. He probably had some out-of-the-way airport where he could come

down, replenish his supply of gas and oil, and get away without being

reported.

Fifteen minutes went by the clock. The needle on the gas gauge dropped

lower. Probably McDowell, up ahead, was chuckling for he certainly knew

the amount of fuel in the monoplane he had left behind.

Prentiss tapped Tim on the shoulder.

"How much longer?"

"Not more than 15 minutes."

"Close in on him and I'll see if this rifle can't convince him that

it's time to come down."

Tim's right hand jammed the throttle on full and the trim monoplane

leaped ahead, overhauling the old trainer rapidly.

McDowell, hearing the deeper drone of the motor behind him, looked back

at them. Tim banked to give Prentiss a clear shot and the federal agent

pressed the trigger. Tim could hear the sharp spats of the gun as the

bullets sped on their way. Holes appeared in the fuselage of McDowell's

ship. Prentiss was shooting better. McDowell, pointing an automatic at

them, emptied the magazine. His aim was wild and not a bullet struck

the monoplane.

McDowell put the old biplane into a dive and Tim promptly followed.

Twisting and turning, they resumed the battle they had waged over the

Atkinson airport. Tim was flying rings around McDowell now and Prentiss

pumped shot after shot toward the biplane but the air was rough and it

was hard to gauge the distance accurately.

"Concentrate on his motor," Tim shouted. "We can't stay up more than

five minutes more and you may be able to put his ship out of

commission."

Prentiss filled the magazine of the rifle again and, firing steadily,

directed his bullets toward the motor of the biplane. Tim could see the

black splashes as the bullets struck the cowling. There was just a

chance that he might be able to disable McDowell's motor.

The motor of their own ship coughed. Tim switched on the emergency tank

and it barked steadily again. Their minutes in the air were numbered

for he had no way of knowing whether the emergency tank was full or how

much it held.

"I'm going to try to bring him down," Tim yelled at Prentiss.

"What are you going to do?"

"See if I can't run my wheels through his prop. Hang on."

"Won't that wreck your landing gear?"

"We'll have to take a chance on that. If it does we'll get down

someway. Are you game?"

"Go ahead," said the inspector grimly. "I'll try it once. There may not

be a second time."

"I'll get you down all in one piece," grinned Tim. Then he turned to

the job at hand.

McDowell was just a little above them and about a thousand feet ahead.

Gunning the motor hard, Tim climbed above their quarry and with the

motor on full, dove headlong for the biplane. McDowell must have sensed

what was in Tim's mind for he stood up in his cockpit and took

deliberate aim with the automatic. Bullets plunked into the wing of the

monoplane, but Tim kept on. Prentiss's rifle was silent for the moment

for at that angle he was unable to fire.

Down they dropped like an eagle after its prey. McDowell dove back into

the cockpit just as the monoplane crashed down on him, the wheels of

the ship above almost raking his head. Tim steeled himself for the

expected crash as the propeller of the biplane bit into the landing

gear but it did not come. By some trick of magic which Tim would never

know McDowell dropped the biplane down almost ten feet at the last

moment. Or perhaps fate had taken a hand and the ship had struck an air

pocket. At any rate the monoplane sped on overhead and McDowell was

safe again.

"What happened?" asked Prentiss.

Tim shook his head. "I don't know. Maybe the biplane hit rough air and

dropped. I thought surely we had him that time."

The motor coughed, rapped out a few more revolutions, and then died.

"That's about all for us," said Tim bitterly.

"And there goes McDowell," said the inspector.

The flying reporter scanned the ground for a safe landing place. They

were up a little better than 4,000 feet. To their right was a small

town and a fair-sized pasture at one edge, flanked by a white highway.

Tim nosed the monoplane down. As they glided toward the field he caught

the sound of another airplane motor. He glanced up. Perhaps McDowell

was coming back. But McDowell's ship was winging steadily along on the

1,200-mile hop to the border.

"Someone back of us," said Prentiss. There was no need to shout now and

the inspector's voice sounded unnatural.

Tim glanced back. The ship was familiar. His heart leaped. It was the

fast Jupiter owned by the _News_. Someone had managed to get it out of

the hangar and was coming to help them.

The flying reporter opened the window on his left and waved wildly,

pointing downward. The pilot of the other plane waggled his wings in

understanding and dropped toward the pasture with Tim following him

down.

"Looks like Tommy Larkin in the other plane," said the inspector.

"That's the _News_' ship and I don't care who's flying it," said Tim,

"just as long as it's got a full tank of gas. McDowell is going to be

in for a surprise when we shoot up in the Jupiter. That's an airplane."

The pasture proved surprisingly smooth and they rolled across the

field. The pilot who had brought in the Jupiter had it swung around and

had it ready for them when they tumbled from the cabin of the monoplane.

"Tommy!" cried the inspector. "Great work, boy!"

"I couldn't stay out of this shindig," grinned the flyer McDowell had

planned to destroy.

"What a break," chuckled Tim. "Plenty of gas?"

"The tank's full to overflowing. That's some plane; fast and easy to

handle."
