Part 43 (1/2)
First Kennedy took out the various rolls of film. Looking up, he caught the face of the operator at the opening in the wall and handed them to him one by one.
”Here are two sections of the opening of the story, scenes one to thirteen of 'The Black Terror' put together in order, but without subt.i.tles. One is printed from the negative of the head camera man, Watkins. The other is exactly the same action as taken by the other photographer. We will run both, but wait for my signal between each piece. Understand?”
”Yes, sir!”
”Now I am giving you two rolls which contain prints of the negative from both cameras of the action at the moment of Werner's death. Those are to be projected in the same way when I give you the signal.
Following that there will be two very short pieces which show the attempt upon the life of Mr. s.h.i.+rley. They are being rushed through the laboratory at this moment and will be brought to you by the time we are ready for them. Finally”--Kennedy paused and as he took the rolls of negative of the snake film I could see that he hesitated to allow them out of his hands even for a few moments--”here is some negative which will be my little climax. It--it is very valuable indeed, so please be careful.”
”You--you want to project the NEGATIVE?” queried the operator.
”Yes. They tell me it can be done, even with negative as old and brittle as this, if you are careful.”
”I'll be careful, sir! You punch the b.u.t.ton there once to stop and two to go. I'll be ready in a moment.” As he spoke he disappeared and soon we heard the unmistakable hiss of the arcs in his machines.
Kennedy stooped and from the bag produced the little envelopes with the pocket knives and nail files, the set of envelopes with the samples of blood, the piece of silk he had cut from the portiere at Tarrytown, the tiny bits he had cut from the towel found by me in the washroom of this studio, and a microscope--the last, I guessed, for effect.
Around in the semidarkness I could see the faces as necks were craned to watch us. Kennedy's deliberateness, his air of certainty, must have struck terror home to some one person in the little audience. Often Kennedy depended upon hidden scientific instruments to catch the faint outward signs of the emotions of his people in a seance of this sort, to allow the comparison of their reactions in the course of his review of the evidence, to give him what amounted to a very sure proof of the one person's guilt. The very absence of some such preparation indicated to me the extent of his confidence.
At length he began his little lecture, for all the world as though this were one of his cla.s.ses at the University, as though there were at stake some matter of chemical reaction.
”I need not tell you, ladies and gentlemen, that this is a highly scientific age in which we live.” His tones were leisurely, businesslike, cool. ”Your own profession, the moving picture, with all its detail of photography and electricity, its blending of art and drama and mechanics, is indicative of that, but”--a pause for emphasis--”it is of my own profession I wish to talk just now, the detection and prevention of crime.
”Criminals as a whole were probably the very first cla.s.s of society to realize the full benefit of modern science. Banks and business inst.i.tutions, the various detective and police forces, all grades and walks of life have been put to it to keep abreast of the development of scientific crime. So true has this been that it is a matter of common belief with many people that the hand of the law may be defied with impunity, that justice may be cheated with absolute certainty, just so long as a guilty man or woman is sufficiently clever and sufficiently careful.
”Fortunately, the real truth is quite the reverse. Science has extended itself in many dimensions of s.p.a.ce. With the use of a microscope, for instance, a whole new world is opened up to the trained detective.
”Everyone knows now that the examination of hands and fingers is an infallible aid in the identification of criminals and in the proof of the presence of a suspect at the scene of a crime--I refer to fingerprints, of course. But fingerprints are only one small detail in this department of investigation. Our criminals know that gloves must be worn, or any smooth surface wiped so as to remove the prints. In that way they believe they cheat the microscope or the pocket lens.
”As a matter of fact few people have thought of another way of gaining evidence from the finger tips, but it is a method possible to the scientist, and is not only practicable but exceedingly effective. In time it will be recognized by all specialists in crime. Now I refer to the deposits under the finger nail.
”Indeed, it is surprising how many things find their way under the nail and into the corners of the cuticle.” Kennedy indicated the files and pocket knives visible in the shaded square of light before him. ”The value of examining finger-nail deposits becomes evident when we realize that everyone carries away in that fas.h.i.+on a sample of every bit of material he handles. To touch a piece of cloth, even lightly, will result in the catching of a few of its fibers. Similarly, the finger nails will deposit either a small or large portion of their acc.u.mulation upon such things as the knife blades or files used to clean them; and there identification still is possible. Nothing in the world is too infinitesimal for use as evidence beneath the microscope.
”In cla.s.sifying these acc.u.mulations”--Kennedy paused and the silence in the little room was death-like--”we may say that there are some which are legitimate and some which are not. It is the latter which concern us now. The first day we were here at the studio, just four days ago now, and immediately following the murder of Miss Lamar, Mr. Jameson discovered a towel in the washroom on the second floor of the office building. On that towel there were spots of Chinese yellow, make-up, as though it had been used to wipe a face or hands by some actor or actress. Those spots were unimportant. There were others, however, of an entirely different nature, together with the mark of blood and a stain which showed that a hypodermic needle had been cleaned upon the towel before it was thrown in the basket.”
Kennedy leaned forward. His eyes traveled from face to face. ”That towel was a dangerous clue.” Now there was a new grim element in his voice. ”That towel alone has given me the evidence on which I shall obtain a conviction in this case. To-day I let it be known that it was in my possession and the guilty man or woman understood at once the value it would be to me. In order to gain additional clues I purposely gave the impression that I had yet to a.n.a.lyze either the spots or the trace of blood. I wanted the towel stolen, and for that purpose I placed the bag containing it in a locker and left the locker unguarded.
I coated the towel with a substance which would cause discomfort and alarm--itching salve--not with the idea that anyone would be foolish enough to go about scratching before my eyes, but with the idea of making that person believe that such was my purpose and with the idea of driving him--or her--to was.h.i.+ng his hands at once and, more, with the idea of forcing him or scaring him into cleaning his fingernails.
”I succeeded. On one of these files or knife blades I have found and identified the fibers of that towel. I do not yet know the person, but I know the mark placed by Mackay on the outside of the little envelope, and when I tell Mackay the mark he will name the guilty person.”
”Mr. Kennedy!” Manton spoke up, impulsively, ”every towel in the studio is the same. I bought them all at the same time. The fibers would all be alike. You have named seven people to me, including myself, as possibly guilty of these--these murders. Your conclusions may be very unjust--and may lead to a serious miscarriage of justice.”
Kennedy was unperturbed. ”This particular towel, in addition to the itching salve, was thoroughly impregnated with a colorless chemical which changed the composition of the fibers in a way easily distinguis.h.i.+ng them from the others under the microscope. Do you see, Mr. Manton?”
The promoter had no more to say.
”Now what connection has the towel with the case? Simply this!” Kennedy picked up one of the tiny pieces he had cut out of it. ”The poison used to kill Miss Lamar was snake venom.” He paused while a little murmur went through his audience, the first sound I had detected. ”These spots on the towel are antivenin. The venom itself is exceedingly dangerous to handle. The guilty man--or woman--took no chances, but inoculated himself with antivenin, protection against any chance action of the poison. The marks on the towel are the marks made by the needle used by that person in taking the inoculation.
”If you will follow me closely you will understand the significance of this. Miss Lamar was killed by the scratch of a needle secreted in the portieres through which she came, playing the scene in Mr. Phelps's library. That I will prove to you when I show you the film. The night following her death some one broke into the room there at Tarrytown and removed the needle. In removing the needle that person scratched himself, or herself. On the portieres I found some tiny spots of blood.” Kennedy paused to hold up the bit of heavy silk. ”I a.n.a.lyzed them and found that the blood serum had changed in character very subtly. I demonstrated that the blood of the person who took the needle contained antivenin, and if necessary I can prove the blood to come from the same individual who wiped the needle on the towel in the studio.”
Kennedy pressed the b.u.t.ton before him, twice. ”Now I want you to see, actually see Miss Lamar meet her death.”
