The Ear in the Wall

XX. The Metric Photograph

Murtha's escape from the sanitarium had again thrown our calculations into chaos. We rode back to the city in silence, and even Kennedy had no explanation to offer.

Even at a late hour that night, although a widespread alarm had been sent out for him, no trace of the missing man could be found. The next morning's papers, of course, were full of the strange disappearance, but gave no hint of his discovery. In fact, all day the search was continued by the authorities, but without result.

On the face of it, it seemed incredible that a man who was so well known, especially to the thousands of police and others in the official and political life of the city, could remain at large unrecognized. Still, I recalled other cases where prominent men had disappeared. The facts in Murtha's case spoke for themselves.

Comparatively little occurred during the day, although the political campaign which had begun with the primaries many weeks before was now drawing nearer its close and the campaigners were getting ready for the final spurt to the finish.

With Kennedy's unmasking of the unprincipled activities of Kahn, that worthy changed his tactics, or at least dropped out of our sight. Mrs. Ogleby lunched with Langhorne and I began to suspect that the shadow that had been placed on her could not have been engaged by Martin Ogleby, for he was not the kind who would take reports of the sort complaisantly. Someone else must be interested.

As for the Black Book itself, I wondered more as time went on that no one made use of it. Even though we gained no hint from Langhorne after the peculiar robbery of his safe, it was impossible to tell whether or not he still retained the detectaphone record. On the other hand, if Dorgan had obtained it by using the services of someone in the criminal hierarchy that Murtha had built up, it would not have been likely that we would have heard anything about it. We were in the position of men fighting several adversaries in the dark without knowing exactly whom we fought.

We had just finished dinner, that night, Kennedy and I, and, as had been the case in most of the waking hours of the previous twenty-four, had been speculating on the possible solution of the mysterious dropping out of sight of Murtha. The evening papers had contained nothing that the morning papers had not already published and Kennedy had tossed the last of an armful into the scrap basket when the buzzer on the door of our apartment sounded.

A young man stood there as I opened the door, and handed me a note, as he touched his hat. "A message for Professor Kennedy from Mr. Carton, sir," he announced.

I recognized him as Carton's valet as he stood impatiently waiting for Craig to read the letter.

"It's all right--there's no answer--I'll see him immediately," nodded Kennedy, tossing the hasty scrawl over to me as the valet disappeared.

"My study at home has been robbed, probably by sneak thieves," read the note. "Would you like to look it over? I can't find anything missing except a bundle of old and valueless photographs. Carton."

"Looks as if someone thought Carton might have got that Black Book from Langhorne," I commented, following the line on which I had been thinking at the time.

"And the taking of the photographs was merely a blind, after not finding it?" Kennedy queried, I cannot say much impressed by my theory.

"Perhaps," I acquiesced weakly, as we went out.

Instead of turning in the direction of Carton's immediately, Kennedy walked across the campus toward the Chemistry Building. At the laboratory we loaded ourselves with a large and heavy oblong case containing a camera and a tripod.

The Cartons lived in an old section of the city which still retained something of its aristocratic air, having been passed by, as it were, like an eddy in the stream of business that swirled uptown, engulfing everything.

It was an old four-story brownstone house which had been occupied by his father and grandfather before him, and now was the home of Carton, his mother, and his sister.

"I'm glad to see you," Carton met us at the door. "This isn't quite as classy a robbery as Langhorne's--but it's just as mysterious. Must have happened while the family were at dinner. That's why I said it was a robbery by a sneak thief."

He was leading the way to his study, which was in an extension of the house, in the rear.

"I hope you've left things as they were," ventured Craig.

"I did," assured Carton. "I know your penchant for such things and almost the first thought I had was that you'd prefer it that way. So I shut the door and sent William after you. By the way, what have you done with him?"

"Nothing," returned Craig. "Isn't he back yet?"

"No--oh, well I don't need him right away."

"And nothing was taken except some old photographs?" asked Craig, looking intently at Carton's face.

"That is all I can find missing," he returned frankly.

Kennedy's examination of the looted study was minute, taking in the window through which the thief had apparently entered, the cabinet he had forced, and the situation in general. Finally he set up his camera with most particular care and took several flashlight pictures of the window, the cabinet, the doors-- including the study--from every angle. Outside he examined the extension and back of the house carefully, noting possible ways of getting from the side street across the fences into the Carton yard.

With Carton we returned to Craig's splendidly equipped photographic studio and while Carton and I made the best of our time by discussing various phases of the case, Kennedy employed the interval in developing his plates.

He had ten or a dozen prints, all of exactly the same size, mounted on stiff cardboard in a space with scales and figures on all four margins. Carton and I puzzled over them.

"Those are metric photographs, such as Bertillon of Paris used to take," Craig explained. "By means of the scales and tables and other methods that have been worked out, we can determine from those pictures distances and many other things almost as well as if we were on the spot ourselves. Bertillon cleared up many crimes with this help, such as the mystery of the shooting in the Hotel Quai d'Orsay and other cases. The metric photograph, I believe, will in time rank with other devices in the study of crime."

He was going over the photographs carefully.

"For instance," he continued, "in order to solve the riddle of a crime, the detective's first task is to study the scene topographically. Plans and elevations of a room or house are made. The position of each object is painstakingly noted. In addition, the all-seeing eye of the camera is called into requisition. The plundered room is photographed, as in this case. I might have done it by placing a foot rule on a table and taking that in the picture. But a more scientific and accurate method has been devised by Bertillon. His camera lens is always used at a fixed height from the ground and forms its image on the plate at an exact focus. The print made from the negative is mounted on a card in a space of definite size, along the edges of which a metric scale is printed. In the way he has worked it out, the distance between any two points in the picture can be determined. With a topographical plan and a metric photograph one can study a crime, as a general studies the map of a strange country. There were several peculiar things that I observed at your house, Carton, and I have here an indelible record of the scene of the crime. Preserved in this way, it cannot be questioned. You are sure that the only thing missing is the photographs?"

Carton nodded, "I never keep anything valuable lying around."

"Well," resumed Kennedy, "the photographs were in this cabinet. There are other cabinets, but none of them seems to have been disturbed. Therefore the thief must have known just what he was after. The marks made in breaking the lock were not those of a jimmy, but of a screwdriver. No amazing command of the resources of science is needed so far. All that is necessary is a little scientific common sense."

Carton glanced at me, and I smiled, for it always did seem so easy, when Craig did it, and so impossible when we tried to go it alone.

"Now, how did the robber get in?" he continued, thoroughly engrossed in his study. "All the windows were supposedly locked. I saw that a pane had been partly cut from this window at the side-- and the pieces were there to show it. But consider the outside, a moment. To reach that window even a tall man must have stood on a ladder or something. There were no marks of a ladder or even of any person in the soft soil of the garden under the window. What is more, that window was cut from the inside. The marks of the diamond which cut it plainly show that. Scientific common sense again."

"Then it must have been someone in the house or at least familiar with it?" I exclaimed.

Kennedy shook his head affirmatively.

I had been wondering who it could be. Certainly this was not the work of Dopey Jack, even if the far cleverer attempt on Langhorne's safe had been. But it might have been one of his gang. I had not got as far as trying to reason out the why of the crime.

"Call up your house, Carton," asked Craig. "See if William, your valet, has returned."

Carton did so, and a moment later turned to us with a look of perplexity on his face. "No," he reported, "he hasn't come back yet. I can't imagine where he is."

"He won't come back," asserted Kennedy positively. "It was an inside job--and he did it."

Carton gasped astonishment.

"At any rate," pursued Kennedy, "one thing we have which the police greatly neglect--a record. We have made some progress in reconstructing the crime, as Bertillon used to call it."

"Strange that he should take only photographs," I mused.

"What were they?" asked Kennedy, and again I saw that he was looking intently at Carton's face.

"Nothing much," returned Carton unhesitatingly, "just some personal photographs--of no real value except to me. Most of them were amateur photographs, too, pictures of myself in various groups at different times and places that I kept for the associations."

"Nothing that might be used by an enemy for any purpose?" suggested Kennedy.

Carton laughed. "More likely to be used by friends," he replied frankly.

Still, I felt that there must have been some sinister purpose back of the robbery. In that respect it was like the scientific cracking of Langhorne's safe. Langhorne, too, though he had been robbed, had been careful to disclaim the loss of anything of value. I frankly had not believed Langhorne, yet Carton was not of the same type and I felt that his open face would surely have disclosed to us any real loss that he suffered or apprehension that he felt over the robbery.

I was forced to give it up, and I think Kennedy, too, had decided not to worry over the crossing of any bridges until at least we knew that there were bridges to be crossed.

Carton was worried more by the discovery that one he had trusted even as a valet had proved unfaithful. He knew, however, as well as we did that one of the commonest methods of the underworld when they wished to pull off a robbery was to corrupt one of the servants of a house. Still, it looked strange, for the laying of such an elaborate plan usually preceded only big robberies, such as jewelery or silver. For myself, I was forced back on my first theory that someone had concluded that Carton had the Black Book, had concocted this elaborate scheme to get what was really of more value than much jewelry, and had found out that Carton did not have the precious detectaphone record, after all. I knew that there were those who would have gone to any length to get it.

A general alarm was given, through the police, for the apprehension of William, but we had small hope that anything would result from it, for at that time Carton's enemies controlled the police and I am not sure but that they would have been just a little more dilatory in apprehending one who had done Carton an injury than if it had been someone else. It was too soon, that night, of course, to expect to learn anything, anyhow.

It was quite late, but it had been a confining day for Kennedy who had spent the hours while not working on Carton's case in some of the ceaseless and recondite investigations of his own to which he was always turning his restless mind.

"Suppose we walk a little way downtown with Carton?" he suggested.

I was not averse, and by the time we arrived in the white light belt of Broadway the theatres were letting out.

Above the gaiety of the crowds one could hear the shrill cry of some belated newsboys, calling an "Extra Special"--the only superlative left to one of the more enterprising papers whose every issue was an "Extra."

Kennedy bought one, with the laughing remark, "Perhaps it's about your robbery, Carton."

It was only a second before the smile on his face changed to a look of extreme gravity. We crowded about him. In red ink across the head of the paper were the words:

"BODY OF MURTHA, MISSING, FOUND IN MORGUE"

Down in a lower corner, in a little box into which late news could be dropped, also in red ink, was the brief account:

This morning the body of an unknown man was found in The Bronx near the Westchester Railroad tracks. He had been run over and badly mutilated. After lying all day in the local morgue, it was transferred, still unidentified, to the city Morgue downtown.

Early this evening one of the night attendants recognized the unidentified body as that of Murtha, "the Smiling Boss," whose escape day before yesterday from an asylum in Westchester has remained a mystery until now.

"Well--what do you--think of that!" ejaculated Carton. "Murtha-- dead--and I thought the whole thing was a job they were putting up on me!"

Kennedy crooked his finger at a cabby who was alertly violating the new ordinance and soliciting fares away from a public cab stand.

"The Morgue--quick!" he ordered, not even noticing the flabbergasted look on the jehu's face, who was not accustomed to carrying people thither from the primrose path of Broadway quite so rapidly.
