CHAPTER III

THE CIPHER

Chester Fay watched the stout form of the Chief of Division as he

crossed the room, tapped lightly on the door which led to the hallway,

then waited with his fingers toying with a heavy, gold chain which

crossed a vest the color of old wine.

MacKeenon turned the knob and came into the room. He closed and locked

the door at Sir Richard’s suggestion. He sniffed the air of the room,

glanced keenly toward Fay, then said:

“Ye have come to an understanding?”

“We have!” declared Sir Richard. “Fay is with us. You know what that

means? We are bound to get the key and trick the Germans.”

“A’ hae noo doot ov it,” said the Scotch detective, rubbing his hands

and peering for a second time at the cracksman. “A verra gude mon—but a

wee bit reckless.”

Sir Richard laughed pleasantly. “Oh, we’re all that way—more or less. I

guess it was recklessness that broke the Hindenburg Line. It would never

have been done if we had counted the cost.”

Fay moved around the end of the table and stood by the three black

boxes. He studied the situation from every angle. It was possible to

escape. It was not too late to go back on his bargain with Sir Richard.

A swift rush, the bowling over of the two detectives, and a plunge

through the shrubbery of the house would carry him to westward, where

quiet, shaded lamps and reaching aisles of mansions would offer freedom

for all time.

He waited to hear more. The gripping mystery of the cipher clutched and

stilled his desire for liberty. There would be other chances at a later

hour.

There was something of the American in Sir Richard. Fay watched the two

detectives come across the room, take seats at the table and then pull

toward themselves the locked boxes.

“We’ll begin at the beginning,” said the chief, glancing up at the

ceiling and then into Fay’s eyes. “Take a seat, Chester, right here! I

want to explain to you about the cipher and the dye business.”

Fay turned and gripped the ornate arms of a teakwood chair which had

certainly come from India in one of the old hulks. He turned this chair

so that the light from the overhead cluster would shine in the faces of

the two detectives and leave his in shadow. It was an old trick!

He sat down, pulled up the knees of his tweed trousers and leaned

slightly forward in an attitude of attention. Sir Richard had already

drawn a small key from his pocket. This key was evidently the one to the

three locks of the boxes.

“What do you know about German dyes?” snapped the chief as he held out

the key. “Know anything at all, Fay?”

“I’ve heard of fast-black.”

“Is that all?”

“About all, Chief. I suppose the Germans have gone deeper into the

subject than most men. I thought the States had made some new

discoveries. You see I didn’t get much chance to read in the last place

I was in. The subject of reading for occasional offenders should be

called to the attention of the Home Secretary.”

“I’ll mention it,” said Sir Richard dryly. “I might add that the Home

Secretary and I have spent three months on this damn cipher.”

Fay leveled his shaded eyes toward the boxes. He glanced at Sir Richard.

There was a frown on the chief’s face and an angry pucker about his

strong mouth.

“Three months, on a cipher! Let me see it, Chief.”

Sir Richard turned toward MacKeenon. “Better get up and stand by the

windows when I open these boxes,” he said. “We can’t be too careful.

There is a billion pounds involved in this!”

Fay was impressed for the first time since leaving the sombre walls of

Dartmoor. Sir Richard was no man to exaggerate. He might have had the

treasure of the Diamond Clique as he reached, pulled a box close up to

his side, inserted the key and slowly lifted the sheet-metal lid.

The cracksman leaned out of the shadow and into the light. Sir Richard

laid the key upon the polished surface of the table, thrust his fingers

inside the box and drew out a sheet of white paper. He held this sheet

so that Fay could read the top lines. They were:

“SCHUCKER—MAINTZ—WERKE—FRANKFORT ON MAIN—BERLIN”

Underneath this heading was an even row of ten-point letters, the first

of which ran:

“aaahhhsssaaacccstopxxxgggssstttstopmmmwwwccc

pppfffbbbstopxxxzzzccceeesssuuukkkwwwssstttst

opyyynnnvvvfffssshhhstopmmmtttnnnpppwwwfffccc”

Fay counted thirty-two rows of similar letters, between the lines of

which were double spaces of blank white. He turned to the box as Sir

Richard replaced the sheet and snapped down the lid.

“They’re all like that,” said the chief bitterly. “It’s a clever, clever

cipher. A cipher that runs through ten reams of paper. There’s all of

six hundred thousand letters in the thing. There’s at least thirty or

forty thousand words. The whole will give us the formulae to such dyes

as Alizarine Sapphire and Carbanthrene Blue.”

“Might be the names of sleeping cars,” said Fay.

“They’re much-wanted dyes! The man who was slain in Switzerland said the

formulae to these two colors would be found in the boxes. They may be

there, but we haven’t found them!”

MacKeenon lowered a blind and turned. He sniffed with the scent of a

baffled hound. The pouches at the side of his cheeks dropped, his teeth

showed beneath curled gums. Fay wheeled upon him suddenly and was

startled at the inspector’s appearance. It was as if the old dog had

snarled in silence.

“We’ll continue,” broke in Sir Richard as he shoved the box upon the

table. “The game isn’t lost! There’s a key to the cipher in the

embassy.”

“Have you tried everything?” asked Fay. “How about these cipher experts?

I’ve heard they can cipher anything. There’s a Russian in Dartmoor who

used to talk to the whole gallery by tapping on his bars. All you had to

know was the key-word and deduct the numbers it represented from the

numbers he sent. The quotient would be the message.”

“We’ve tried that,” snapped Sir Richard. “Believe me, Fay, that was the

first thing tried. It’s the Nihilist key-word cipher! Fifty of the

keenest brains in Europe and America have worked on this thing. It does

not follow Bacon’s biliteral cipher or Poe’s cryptogram. It has some of

the marks of an old Italian cipher used in the time of Pope Alexander.

It isn’t that! It has already driven one professor of mathematics mad.

He cross-indexed it and tried it backward. He found a queer average in

the repetition of certain letters. They followed no sane rule. For that

reason he went insane. More may go mad if this thing isn’t solved. It

represents the final triumph over Germany—the winning of the commercial

war which is upon us!”

Fay drew his head back into the shadow. He still retained the ringing

timbre of Sir Richard’s voice. The energetic chief of the Intelligence

Division had once been on a mission to the States. He had learned much

that was American on that visit.

“Damnit!” he heard Sir Richard blurt. “We’re not children! We have

defeated the Germans on the field of battle. Why can’t we solve a simple

cipher?”

“What did you pay for it?” Fay shot the question out of the shadow and

watched its effect on Sir Richard’s features.

“Pay for it? What do you mean, Fay?”

“What did you pay that man in Switzerland?”

“Ten thousand pounds.”

“And the fellow in Holland?”

“He died too soon to receive his share. The money went to the general

funds.”

Fay crossed his legs and glanced at the slender shape of the boots he

wore. “I think you have been gulled,” he said with the ghost of a smile.

“I think that cipher in the boxes is a bum steer, if you know what that

means. You tossed away ten thousand pounds—like that!” Fay threw out his

hand expressively.

Sir Richard blinked both eyes. The frown died from his face, wrinkle by

wrinkle. He leaned back in his chair, thrust his knees against the edge

of the table and said, half to Fay, half to MacKeenon:

“Mac thought the same thing! You’re both wrong. The thing was tested

before the money was paid. The agent who completed the transaction in

Switzerland made no mistake. He went to extreme length in the matter.”

“How?” asked Fay.

“He named a dye—a fast blue—which the German chemist said was one of the

thirty-six which were fully worked out in the formulae. The chemist took

the boxes, went into a room, and came out with the formula of the

fast-blue, down to the last reaction. It couldn’t be done by any trick

of memory!”

“That sounds plausible,” Fay said. “Then it is no hoax?”

“It’s straight goods, Fay! The five thousand sheets in these three boxes

contain the chemical formulae for the thirty-six dyes. The devil of it

is, we lost the key, in—the country north and east of here. You’re going

to get that key for us!”

“Just a moment. Isn’t it possible that the whole thing is a blind?”

“Be clear!”

“I mean that the lines of letters, thirty-two or three on each page, are

there for a gull?”

“Go on!”

“They might be a gull for fools to go mad about. The real cipher may be

within the lines. That also is a common practice at Dartmoor. Men have

received letters from the outside which are written with lemon juice

between the lines. All they did was to heat the paper and the message

came out in brown ink.”

Sir Richard smiled broadly. “That has been thought of,” he said,

glancing at MacKeenon. “To be frank, as I said, everything has been

tried. We’ve even split some of the paper. We’ve tried every reaction

known to science. We’ve bathed the sheets in oxalic acid and iodine.

There was only one clue in this direction.”

Fay lifted his hand and fingered the pearl-pin in his cravat.

“That one clue,” continued Sir Richard, “was the report of an American

chemist that he detected a salt in the composition of the paper. It was

so faint, however, that nothing came of it. We’re squarely up against

the last card—that big gopher in the embassy!”

Fay frowned slightly at the chief’s use of an American yegg’s pet name

for a strong-box. It showed Sir Richard’s versatility, and also showed

the cracksman what manner of man he was dealing with.

“Gopher has gone out,” said Fay in correction. “Only the low-brows of

the Middle Western States use it. You should say: ‘can or jug or

keister.’”

“We’ll compromise on ‘crib,’ a good old word used in the time of Jack

Cade and other mid-Victorian gentlemen!”

“All right, Chief! You want me to take it—without trace. In it I’m to

find the key to the cipher—if there is a key. What can you say

concerning the key? Is it a book, paper or design of some kind?”

“Now we’re getting close!” Sir Richard exclaimed. “It is a small packet

in the back of the embassy’s crib. It was seen only last week by a

trusted agent who could go no further. This agent informs me that the

neutral nation, north and east of here, is in a quandary concerning it.

Germany has requested that the packet be returned over her border.”

“Any marks of identification?”

“Yes! You will always know it by a name written in ink across one

corner, under a blue string. The name is Otto Mononsonburg—the man who

was stabbed in the back, near the Schwartz Canal.”

“Ah,” said Fay, “the matter seems easy. I get my freedom?”

“If you get the packet and turn it over to me.”

“I’ll get it! Now a number of other things, Sir Richard—” Fay turned and

stared at the lurking figure of the Scotch inspector. MacKeenon lifted

his hand and stroked his jaw with a sly motion. His eyes swung from

Fay’s to Sir Richard’s. They held the glint of the manhunter and the

hound. A tawny fire was in them.

For the second time that evening there came an air of tenseness into the

room. Fay felt it as he watched the Scotch inspector. Try, as he should,

he could never get over the feeling that the detective was his born

enemy.

MacKeenon was so like a waiting collie. The leathern pouches of the

Scot—the curl to his lips—the fang-like teeth, all made this thing seem

real.

With Sir Richard Colstrom there was this difference. The chief had

traveled far. He had taken the pains to acquire some of the argot of the

underworld. He was rated square—after he caught his quarry. Fay could

never believe that a manhunter played a fair game in running down

criminals. There was too much oral evidence to the contrary. There had

been a number of stool-pigeons in his life. To him, the despicable thing

about the game was the traitors.

Born a gentleman’s son and riding swiftly through a moderate fortune,

Fay had taken the easier way. He had paid! There were other convictions

beside the Hatton Gardens affair recorded at Scotland Yard.

Freedom was a precious thing. He gripped his lips with his teeth and

counted ten before he said to Sir Richard:

“One of the conditions of this matter is that I have no hell-hounds of

the law trailing me!”

Sir Richard glanced at MacKeenon. The two men understood each other down

to the fraction of a glance.

“That’s all right,” said Sir Richard soothingly. “You can go scot-free.

All we want is the key to the cipher. Then, afterwards, you can wear

that perfectly good suit to the States instead of donning the broad

arrow at Dartmoor.”

“Fine!” said Fay without warmth. “Now another matter—”

“What is it?”

“Money!”

“You can have it.”

“I’ll need a hundred pounds, now!”

Sir Richard drew from his inner vest-pocket a thin bill-fold, which he

opened upon the table. From this he extracted ten ten-pound notes and

tossed them to Fay.

“Count them,” he said as he replaced the bill-fold and made an entry in

the little book which he had already consulted when giving the data

concerning the strong-box in the embassy.

“One hundred, correct!” said the cracksman, crinkling the sheath of

white papers. “Clean notes! I shall have to lose a shilling on the pound

with these.”

“That’s the rate the fences get, eh?”

Fay smiled as he thrust the bills in his tweed trousers. “How should I

know?” he inquired with good-nature.

Sir Richard stared at MacKeenon. Both detectives mirrored Fay’s engaging

manner. The tensity of the air had vanished.

“You’ll get another hundred pounds when you start,” Sir Richard said,

tapping the table. “When will you start?”

“There’s another matter, Chief.”

“And that is—?”

“Passports and clearance papers or whatever you call them. I understand

there is still some difficulty on account of customs. I might as well

travel to Holland, first-class. That means a damn fine alibi of the

superior order. Have you any suggestions?”

Sir Richard fingered the lapel of his coat. He turned this down after

thought. Fay leaned forward. He saw a little silver greyhound pinned

there. It was a passport in a million!

“Do you know what this represents?” asked Sir Richard.

Fay nodded his head and stared at the insignia. “It’s the badge of the

King’s Couriers.”

“Correct!”

“Do I get one?”

“I can tell you where there is one which can be—stolen.”

“Where?”

Sir Richard allowed his lapel to flap back.

He rested his elbows on the edge of the table and fastened upon Fay’s

eager face the cold scrutiny of a master advising a novice.

“The King’s Couriers,” he said impressively, “is an ancient and

honorable order. The members of the office are chosen for fidelity and

speed—hence the greyhound. They can go anywhere by showing the insignia.

They need no passports or papers. Show this to a custom officer and he

will pass your luggage. Show this little badge to a Mandarin in China or

a Zelot in Afghanistan and it is all the same. You get through!”

“Where can I get one?”

Sir Richard beamed at Fay’s enthusiasm. “There’s a courier living in

Richmond Hill who has what you want,” said the chief. “This courier has

been to—the country north and east of here. From this courier you not

only will obtain the little silver greyhound, but also a detailed

description of the embassy where the key to the cipher is. I would

suggest that you turn the courier’s place of residence off tomorrow

night. We’ll give out that you escaped from Dartmoor and entered London

in some surprising manner. What would be more natural than you robbing a

house for clothes and papers? That will let us out in case of

complications with the neutral nation.”

“You mean if I get caught?”

“Stranger things than that have happened. Now, Fay—”

Sir Richard pulled down the lapels of his coat and rose to his feet. He

pressed back the chair with his legs. He cleared his throat.

“Now, Fay,” he continued impressively, “you have everything. The address

in Richmond Hill is Number 4, Rose Crescent. Go there tomorrow about

midnight and prowl the house. Get the little silver greyhound and talk

things over with the courier—who failed to do what you are going to do.”

Fay moved toward the door after picking up his cap. MacKeenon glided to

his side. The cracksman stood erect. He turned slowly and stared at Sir

Richard, who was studying the cipher boxes.

“Au revoir,” said Fay.

The chief swung his head and rested his chin on his chest.

“Same to you,” he said. “You’re hep! Now blow! Mum’s the office, pal!

The ducat and more kale will be ready for you at London Bridge Station

when you’re ready to go. Inspector MacKeenon, the niftiest gumshoe

runner out of the Yard, will fetch them at your order. Eh, Mac?”

“Weil, I don’ know! I daurna disagree wi’ twa o’ you!”

Sir Richard came back to respectability as he lifted his chin and

advanced his hand toward Fay.

“Drop around Cockspur Street and the Strand,” he said. “Get the old, old

moss out of your head, Fay. Talk to the splendid men of your own country

who made victory possible. The town is full of Pershing’s boys! And

Fay—”

The cracksman’s hand was on the door.

“What is it?” he asked.

“Don’t overlook the trifles. They beat you before!”

“I’ll watch out for them!”

“And, Fay—”

“Y—es!”

“Don’t look for Saidee Isaacs. Go right to Number 4, Rose Crescent and

turn the house off. You know how to do that!”

Fay was half through the doorway. Sir Richard made a signal for

MacKeenon to draw back. The inspector’s face clouded as he caught the

order. He peered around the edge of the chamfering. His eyes snapped

like a wiry terrier’s as he heard the swift patter of footsteps on the

pavement.

“He’s goon, mon!” he said. “Fay’s goon!”

“Good!” said Sir Richard.
