"Humph," grunted Kennedy, as we were leaving the store. "You wouldn't

believe it, but it is the hardest thing in the world to get an accurate

description of any one. The psychologists have said enough about it,

but you don't realise it until you are up against it. Why, that might

have been the DeMott woman just as well as the former Miss Sanderson,

and the man might have been Bolton Brown as well as Dawson, for all we

know. They've both disappeared now. I wish we could get some word about

that photograph. That would settle it."

In the last mail that night Kennedy received back the letter which he

had addressed to Michael Dawson. On it was stamped "Returned to sender.

Owner not found."

Kennedy turned the letter over slowly and looked at the back of it

carefully.

"On the contrary," he remarked, half to himself, "the owner was found.

Only he returned the letter back to the postman after he had opened it

and found that it was just a note of no importance which I scribbled

just to see if he was keeping in touch with things from his

hiding-place, wherever it is."

"How do you know he opened it?" I asked.

"Do you see those blots on the back? I had several of these envelopes

prepared ready for use when I needed them. I had some tannin placed on

the flap and then covered thickly with gum. On the envelope itself was

some iron sulphate under more gum. I carefully sealed the letter, using

very little moisture. The gum then separated the two prepared parts.

Now if that letter were steamed open the tannin and the sulphate would

come together, run, and leave a smudge. You see the blots? The

inference is obvious."

Clearly, then, our chase was getting warmer. Dawson had been in

Atlantic City at least within a few days. The fruit company steamer to

South America on which Carroll believed he was booked to sail under an

assumed name and with an assumed face was to sail the following noon.

And still we had no word from Chicago as to the destination of the

photograph, or the identity of the man in the Van Dyke beard who had

been so particular to disarm suspicion in the purchase of the plate

from the photographer a few days before.

The mail also contained a message from Williams of the Surety Company

with the interesting information that Bolton Brown's attorney had

refused to say where his client had gone since he had been released on

bail, but that he would be produced when wanted. Adele DeMott had not

been seen for several days in Chicago and the police there were of the

opinion that she had gone to New York, where it would be pretty easy

for her to pass unnoticed. These facts further complicated the case and

made the finding of the photograph even more imperative.

If we were going to do anything it must be done quickly. There was no

time to lose. The last of the fast trains for the day had left and the

photograph, even though it were found, could not possibly reach us in

time to be of use before the steamer sailed from Brooklyn. It was an

emergency such as Kennedy had never yet faced, apparently physically

insuperable.

But, as usual, Craig was not without some resource, though it looked

impossible to me to do anything but make a hit or miss arrest at the

boat. It was late in the evening when he returned from a conference

with an officer of the Telegraph and Telephone Company to whom Williams

had given him a card of introduction. The upshot had been that he had

called up Chicago and talked for a long time with Professor Clark, a

former classmate of ours who was now in the technology school of the

university out there. Kennedy and Clark had been in correspondence for

some time, I knew, about some technical matters, though I had no idea

what it was they concerned.

"There's one thing we can always do," I remarked as we walked slowly

over to the laboratory from our apartment.

"What's that?" he asked absent-mindedly, more from politeness than

anything else.

"Arrest every one with a Van Dyke beard who goes on the boat

to-morrow," I replied.

Kennedy smiled. "I don't feel prepared to stand a suit for false

arrest," he said simply, "especially as the victim would feel pretty

hot if we caused him to miss his boat. Men with beards are not so

uncommon, after all."

We had reached the laboratory. Linemen were stringing wires under the

electric lights of the campus from the street to the Chemistry Building

and into Kennedy's sanctum.

That night and far into the morning Kennedy was working in the

laboratory on a peculiarly complicated piece of mechanism consisting of

electromagnets, rolls, and a stylus and numerous other contrivances

which did not suggest to my mind anything he had ever used before in

our adventures. I killed time as best I could watching him adjust the

thing with the most minute care and precision. Finally I came to the

conclusion that as I was not likely to be of the least assistance, even

if I had been initiated into what was afoot, I had as well retire.

"There is one thing you can do for me in the morning, Walter," said

Kennedy, continuing to work over a delicate piece of clockwork which

formed a part of the apparatus. "In case I do not see you then, get in

touch with Williams and Carroll and have them come here about ten

o'clock with an automobile. If I am not ready for them then I'm afraid

I never shall be, and we shall have to finish the job with the lack of

finesse you suggested by arresting all the bearded men."

Kennedy could not have slept much during the night, for though his bed

had been slept in he was up and away before I could see him again. I

made a hurried trip downtown to catch Carroll and Williams and then

returned to the laboratory, where Craig had evidently just finished a

satisfactory preliminary test of his machine.

"Still no message," he began in reply to my unspoken question. He was

plainly growing restless with the inaction, though frequent talks over

long-distance with Chicago seemed to reassure him. Thanks to the

influence of Williams he had at least a direct wire from his laboratory

to the city which was now the scene of action.

As nearly as I could gather from the one-sided conversations I heard

and the remarks which Kennedy dropped, the Chicago post-office

inspectors were still searching for a trace of the package from

Atlantic City which was to reveal the identity of the man who had

passed the bogus checks and sold the forged certificates of stock.

Somewhere in that great city was a photograph of the promoter and of

the woman who was aiding him to escape, taken in Atlantic City and sent

by mail to Chicago. Who had received it? Would it be found in time to

be of use? What would it reveal? It was like hunting for a needle in a

haystack, and yet the latest reports seemed to encourage Kennedy with

the hope that the authorities were at last on the trail of the secret

office from which the stock had been sold. He was fuming and wishing

that he could be at both ends of the line at once.

"Any word from Chicago yet?" appealed an anxious voice from the doorway.

We turned. There were Carroll and Williams who had come for us with an

automobile to go over to watch at the wharf in Brooklyn for our man. It

was Carroll who spoke. The strain of the suspense was telling on him

and I could readily imagine that he, like so many others who had never

seen Kennedy in action, had not the faith in Craig's ability which I

had seen tested so many times.

"Not yet," replied Kennedy, still busy about his apparatus on the

table. "I suppose you have heard nothing?"

"Nothing since my note of last night," returned Williams impatiently.

"Our detectives still insist that Bolton Brown is the man to watch, and

the disappearance of Adele DeMott at this time certainly looks bad for

him."

"It does, I admit," said Carroll reluctantly. "What's all this stuff on

the table?" he asked, indicating the magnets, rolls, and clockwork.

Kennedy did not have time to reply, for the telephone bell was tinkling

insistently.

"I've got Chicago on the wire," Craig informed us, placing his hand

over the transmitter as he waited for long-distance to make the final

connection. '"I'll try to repeat as much of the conversation as I can

so that you can follow it. Hello--yes--this is Kennedy. Is that you,

Clark? It's all arranged at this end. How's your end of the line? Have

you a good connection? Yes? My synchroniser is working fine here, too.

All right. Suppose we try it. Go ahead."

As Kennedy gave a few final touches to the peculiar apparatus on the

table, the cylindrical drum before us began slowly to revolve and the

stylus or needle pressed down on the sensitised paper with which the

drum was covered, apparently with varying intensity as it turned. Round

and round the cylinder revolved like a graphophone.

"This," exclaimed Kennedy proudly, "is the 'electric eye,' the

telelectrograph invented by Thorne Baker in England. Clark and I have

been intending to try it out for a long time. It at last makes possible

the electric transmission of photographs, using the telephone wires

because they are much better for such a purpose than the telegraph

wires."

Slowly the needle was tracing out a picture on the paper. It was only a

thin band yet, but gradually it was widening, though we could not guess

what it was about to reveal as the ceaseless revolutions widened the

photographic print.

"I may say," explained Kennedy as we waited breathlessly, "that another

system known as the Korn system of telegraphing pictures has also been

in use in London, Paris, Berlin, and other cities at various times for

some years. Korn's apparatus depends on the ability of the element

selenium to vary the strength of an electric current passing through it

in proportion to the brightness with which the selenium is illuminated.

A new field has been opened by these inventions which are now becoming

more and more numerous, since the Korn system did the pioneering.

"The various steps in sending a photograph by the Baker telelectrograph

are not so difficult to understand, after all. First an ordinary

photograph is taken and a negative made. Then a print is made and a wet

plate negative is printed on a sheet of sensitised tinfoil which has

been treated with a single-line screen. You know a halftone consists of

a photograph through a screen composed of lines running perpendicular

to each other--a coarse screen for newspaper work, and a fine screen

for better work, such as in magazines. Well, in this case the screen is

composed of lines running parallel in one direction only, not crossing

at right angles. A halftone is composed of minute points, some light,

some dark. This print is composed of long shaded lines, some parts

light, others dark, giving the effect of a picture, you understand?"

"Yes, yes," I exclaimed, thoroughly excited. "Go on."

"Well," he resumed as the print widened visibly, "this tinfoil negative

is wrapped around a cylinder at the other end of the line and a stylus

with a very delicate, sensitive point begins passing over it, crossing

the parallel lines at right angles, like the other lines of a regular

halftone. Whenever the point of the stylus passes over one of the

lighter spots on the photographic print it sends on a longer electrical

vibration, over the darker spots a shorter vibration. The ever changing

electrical current passes up through the stylus, vibrates with ever

varying degrees of intensity over the thousand miles of telephone wire

between Chicago and this instrument here at the other end of the line.

"In this receiving apparatus the current causes another stylus to pass

over a sheet of sensitised chemical paper such as we have here. The

receiving stylus passes over the paper here synchronously with the

transmitting stylus in Chicago. The impression which each stroke of the

receiving stylus makes on the paper is black or light, according to the

length of the very quickly changing vibrations of the electric current.

White spots on the photographic print come out as black spots here on

the sensitised paper over which this stylus is passing, and vice versa.

In that way you can see the positive print growing here before your

very eyes as the picture is transmitted from the negative which Clark

has prepared and is sending from Chicago."

As we bent over eagerly we could indeed now see what the thing was

doing. It was reproducing faithfully in New York what could be seen by

the mortal eye only in Chicago.

"What is it?" asked Williams, still half incredulous in spite of the

testimony of his eyes.

"It is a photograph which I think may aid us in deciding whether it is

Dawson or Brown who is responsible for the forgeries," answered

Kennedy, "and it may help us to penetrate the man's disguise yet,

before he escapes to South America or wherever he plans to go."

"You'll have to hurry," interposed Carroll, nervously looking at his

watch. "She sails in an hour and a half and it is a long ride over to

the pier even with a fast car."

"The print is almost ready," repeated Kennedy calmly. "By the way, it

is a photograph which was taken at Atlantic City a few days ago for a

booklet which the Lorraine was getting out. The By-Products forger

happened to get in it and he bribed the photographer to give him the

plate and take another picture for the booklet which would leave him

out. The plate was sent to a little office in Chicago, discovered by

the post-office inspectors, where the forged stock certificates were

sold. I understood from what Clark told me over the telephone before he

started to transmit the picture that the woman in it looked very much

like Adele DeMott. Let us see."

The machine had ceased to revolve. Craig stripped a still wet

photograph off the telelectrograph instrument and stood regarding it

with intense satisfaction. Outside, the car which had been engaged to

hurry us over to Brooklyn waited. "Morphine fiends," said Kennedy as he

fanned the print to dry it, "are the most unreliable sort of people.

They cover their tracks with almost diabolical cunning. In fact they

seem to enjoy it. For instance, the crimes committed by morphinists are

usually against property and character and based upon selfishness, not

brutal crimes such as alcohol and other drugs induce. Kleptomania,

forgery, swindling, are among the most common.

"Then, too, one of the most marked phases of morphinism is the pleasure

its victims take in concealing their motives and conduct. They have a

mania for leading a double life, and enjoy the deception and mask which

they draw about themselves. Persons under the influence of the drug

have less power to resist physical and mental impressions and they

easily succumb to temptations and suggestions from others. Morphine

stands unequalled as a perverter of the moral sense. It creates a

person whom the father of lies must recognise as kindred to himself. I

know of a case where a judge charged a jury that the prisoner, a

morphine addict, was mentally irresponsible for that reason. The judge

knew what he was talking about. It subsequently developed that he had

been a secret morphine fiend himself for years."

"Come, come," broke in Carroll impatiently, "we're wasting time. The

ship sails in an hour and unless you want to go down the bay on a tug

you've got to catch Dawson now or never. The morphine business

explains, but it does not excuse. Come on, the car is waiting. How long

do you think it will take us to get over to---"

"Police headquarters?" interrupted Craig. "About fifteen minutes. This

photograph shows, as I had hoped, the real forger. John Carroll, this

is a peculiar case. You have forged the name of the president of your

company, but you have also traced your own name very cleverly to look

like a forgery. It is what is technically known as auto-forgery,

forging one's own handwriting. At your convenience we'll ride down to

Centre Street directly."

Carroll was sputtering and almost frothing at the mouth with rage which

he made no effort to suppress. Williams was hesitating, nonplussed,

until Kennedy reached over unexpectedly and grasped Carroll by the arm.

As he shoved up Carroll's sleeve he disclosed the forearm literally

covered with little punctures made by the hypodermic needle.

"It may interest you," remarked Kennedy, still holding Carroll in his

vise-like grip, while the drug fiend's shattered nerves caused him to

cower and tremble, "to know that a special detective working for me has

located Mr. and Mrs. Dawson at Bar Harbor, where they are enjoying a

quiet honeymoon. Brown is safely in the custody of his counsel, ready

to appear and clear himself as soon as the public opinion which has

been falsely inflamed against him subsides. Your plan to give us the

slip at the last moment at the wharf and board the steamer for South

America has miscarried. It is now too late to catch it, but I shall

send a wireless that will cause the arrest of Miss DeMott the moment

the ship touches an American port at Colon, even if she succeeds in

eluding the British authorities at Kingston. The fact is, I don't much

care about her, anyway. Thanks to the telelectrograph here we have the

real criminal."

Kennedy slapped down the now dry print that had come in over his

"seeing over a wire" machine. Barring the false Van Dyke beard, it was

the face of John Carroll, forger and morphine fiend. Next him in the

picture in the brilliant and fashionable dining-room of the Lorraine

was sitting Adele DeMott who had used her victim, Bolton Brown, to

shield her employer, Carroll.

IX

THE UNOFFICIAL SPY

"Craig, do you see that fellow over by the desk, talking to the night

clerk?" I asked Kennedy as we lounged into the lobby of the new Hotel

Vanderveer one evening after reclaiming our hats from the plutocrat who

had acquired the checking privilege. We had dined on the roof garden of

the Vanderveer apropos of nothing at all except our desire to become

acquainted with a new hotel.

"Yes," replied Kennedy, "what of him?"

"He's the house detective, McBride. Would you like to meet him? He's

full of good stories, an interesting chap. I met him at a dinner given

to the President not long ago and he told me a great yarn about how the

secret service, the police, and the hotel combined to guard the

President during the dinner. You know, a big hotel is the stamping

ground for all sorts of cranks and crooks."

The house detective had turned and had caught my eye. Much to my

surprise, he advanced to meet me.

"Say,--er--er--Jameson," he began, at last recalling my name, though he

had seen me only once and then for only a short time. "You're on the

Star, I believe?"

"Yes," I replied, wondering what he could want.

"Well--er--do you suppose you could do the house a little--er--favour?"

he asked, hesitating and dropping his voice.

"What is it?" I queried, not feeling certain but that it was a veiled

attempt to secure a little free advertising for the Vanderveer. "By the

way, let me introduce you to my friend Kennedy, McBride."

"Craig Kennedy?" he whispered aside, turning quickly to me. I nodded.

"Mr. Kennedy," exclaimed the house man deferentially, "are you very

busy just now?"

"Not especially so," replied Craig. "My friend Jameson was telling me

that you knew some interesting yarns about hotel detective life. I

should like to hear you tell some of them, if you are not yourself

too---"

"Perhaps you'd rather see one instead?" interrupted the house

detective, eagerly scanning Craig's face.

"Indeed, nothing could please me more. What is it--a 'con' man or a

hotel 'beat'?"

McBride looked about to make sure that no one was listening. "Neither,"

he whispered. "It's either a suicide or a murder. Come upstairs with

me. There isn't a man in the world I would rather have met at this very

instant, Mr. Kennedy, than yourself."

We followed McBride into an elevator which he stopped at the fifteenth

floor. With a nod to the young woman who was the floor clerk, the house

detective led the way down the thickly carpeted hall, stopping at a

room which, we could see through the transom, was lighted. He drew a

bunch of keys from his pocket and inserted a pass key into the lock.

The door swung open into a sumptuously fitted sitting-room. I looked

in, half fearfully, but, although all the lights were turned on, the

room was empty. McBride crossed the room quickly, opened a door to a

bedroom, and jerked his head back with a quick motion, signifying his

desire for us to follow.

Stretched lifeless on the white linen of the immaculate bed lay the

form of a woman, a beautiful woman she had been, too, though not with

the freshness which makes American women so attractive. There was

something artificial about her beauty, the artificiality which hinted

at a hidden story of a woman with a past.

She was a foreigner, apparently of one of the Latin races, although at

the moment in the horror of the tragedy before us I could not guess her

nationality. It was enough for me that here lay this cold, stony, rigid

beauty, robed in the latest creations of Paris, alone in an elegantly

furnished room of an exclusive hotel where hundreds of gay guests were

dining and chatting and laughing without a suspicion of the terrible

secret only a few feet distant from them.

We stood awestruck for the moment.

"The coroner ought to be here any moment," remarked McBride and even

the callousness of the regular detective was not sufficient to hide the

real feelings of the man. His practical sense soon returned, however,

and he continued, "Now, Jameson, don't you think you could use a little

influence with the newspaper men to keep this thing off the front

pages? Of course something has to be printed about it. But we don't

want to hoodoo the hotel right at the start. We had a suicide the other

day who left an apologetic note that was played up by some of the

papers. Now comes this affair. The management are just as anxious to

have the crime cleared up as any one--if it is a crime. But can't it be

done with the soft pedal? We will stop at nothing in the way of

expense--just so long as the name of the Vanderveer is kept in the

background. Only, I'm afraid the coroner will try to rub it in and make

the thing sensational."

"What was her name?" asked Kennedy. "At least, under what name was she

registered?"

"She was registered as Madame de Nevers. It is not quite a week now

since she came here, came directly from the steamer Tripolitania. See,

there are her trunks and things, all pasted over with foreign labels,

not an American label among them. I haven't the slightest doubt that

her name was fictitious, for as far as I can see all the ordinary marks

of identification have been obliterated. It will take time to identify

her at the best, and in the meantime, if a crime has been committed,

the guilty person may escape. What I want now, right away, is action."

"Has nothing in her actions about the hotel offered any clue, no matter

how slight?" asked Kennedy.

"Plenty of things," replied McBride quickly. "For one thing, she didn't

speak very much English and her maid seemed to do all the talking for

her, even to ordering her meals, which were always served here. I did

notice Madame a few times about the hotel, though she spent most of her

time in her rooms. She was attractive as the deuce, and the men all

looked at her whenever she stirred out. She never even noticed them.

But she was evidently expecting some one, for her maid had left word at

the desk that if a Mr. Gonzales called, she was at home; if any one

else, she was out. For the first day or two she kept herself closely

confined, except that at the end of the second day she took a short

spin through the park in a taxicab--closed, even in this hot weather.

Where she went I cannot say, but when they returned the maid seemed

rather agitated. At least she was a few minutes later when she came all

the way downstairs to telephone from a booth, instead of using the room

telephone. At various times the maid was sent out to execute certain

errands, but always returned promptly. Madame de Nevers was a genuine

woman of mystery, but as long as she was a quiet mystery, I thought it

no business of ours to pry into the affairs of Madame."

"Did she have any visitors? Did this Mr. Gonzales call?" asked Kennedy

at length.

"She had one visitor, a woman who called and asked if a Madame de

Nevers was stopping at the hotel," answered McBride. "That was what the

clerk was telling me when I happened to catch sight of you. He says

that, obedient to the orders from the maid, he told the visitor that

Madame was not at home."

"Who was this visitor, do you suppose?" asked Craig. "Did she leave any

card or message? Is there any clue to her?"

The detective looked at him earnestly for a time as if he hesitated to

retail what might be merely pure gossip.
