The Poisoned Pen [75]
remainder of the day Kennedy was closely confined in his laboratory with his microscopes, slides, chemicals, test-tubes, and other apparatus. As for myself, I put in the time speculating which of the fakirs had been in some mysterious way connected with the case and in what manner. Many were the theories which I had formed and the situations I conjured up, and in nearly all I had one central figure, the young man whose escapades had been the talk of even the fast set of a fast society. That night Kennedy, with the assistance of First Deputy O'Connor, who was not averse to taking any action within the law toward the soothsayers, assembled a curiously cosmopolitan crowd in his laboratory. Besides the Gilberts were Dudley Lawton and his father, Hata, the Pandit, the Swami, and the Guru - the latter four persons in high dudgeon at being deprived of the lucrative profits of a Sunday night. Kennedy began slowly) leading gradually up to his point: "A new means of bringing criminals to justice has been lately studied by one of the greatest scientific detectives of crime in the world, the man to whom we are indebted for our most complete systems of identification and apprehension." Craig paused and fingered the microscope before him thoughtfully. "Human hair," he resumed, "has recently been the study of that untiring criminal scientist, M. Bertillon. He has drawn up a full, classified, and graduated table of all the known colours of the human hair, a complete palette, so to speak, of samples gathered in every quarter of the globe. Henceforth burglars, who already wear gloves or paint their fingers with a rubber composition for fear of leaving finger-prints, will have to wear close-fitting caps or keep their heads shaved. Thus he has hit upon a new method of identification of those sought by the police. For instance, from time to time the question arises whether hair is human or animal. In such cases the microscope tells the answer truthfully. "For a long time I have been studying hair, taking advantage of those excellent researches by M. Bertillon. Human hair is fairly uniform, tapering gradually. Under the microscope it is practically always possible to distinguish human hair from animal. I shall not go into the distinctions, but I may add that it is also possible to determine very quickly the difference between all hair, human or animal, and cotton with its corkscrew-like twists, linen with its jointed structure, and silk, which is long, smooth, and cylindrical." Again Kennedy paused as if to emphasise this preface. "I have here," he continued, "a sample of hair." He had picked up a microscope slide that was lying on the table. It certainly did not look very thrilling - a mere piece of glass, that was all. But on the glass was what appeared to be merely a faint line. "This slide," he said, holding it up, "has what must prove an unescapable clue to the identity of the man responsible for the disappearance of Miss Gilbert. I shall not tell you yet who he is, for the simple reason that, though I could make a shrewd guess, I do not yet know what the verdict of science is, and in science we do not guess where we can prove. "You will undoubtedly remember that when Miss Gilbert's body was discovered, it bore no evidence of suicide, but on the contrary the marks of violence. Her fists were clenched, as if she had struggled with all her power against a force that had been too much for her. I examined her hands, expecting to find some evidence of a weapon she had used to defend herself. Instead, I found what was more valuable. Here on this slide are several hairs that I found tightly grasped in her rigid hands." I could not help recalling Kennedy's remark earlier in the case - that=20it hung on slender threads. Yet how strong might not those threads prove! "There was also in her pocketbook a newspaper clipping bearing the advertisements of several clairvoyants," he went on. "Mr. Jameson and myself had already discovered what the police had failed to find, that on the morning of the day on which she disappeared Miss
