“Much stress has been laid upon the fact that the accused offered a very large reward for the knife with which this murder was done; that no thief came forward to claim that extraordinary reward; that the latter fact was good circumstantial evidence that the claim that the knife had been stolen was a vanity and a fraud; that these details taken in connection with the memorable and apparently prophetic speech of the deceased concerning that knife, and the final discovery of that very knife in the fatal room where no living person was found present with the slaughtered man but the owner of the knife and his brother, form an indestructible chain of evidence which fixes the crime upon those unfortunate strangers.
“But I shall presently ask to be sworn, and shall testify that there was a large reward offered for the thief, also; and it was offered secretly and not advertised; that this fact was indiscreetly mentioned—or at least tacitly admitted—in what was supposed to be safe circumstances, but may not have been. The thief may have been present himself. [Tom Driscoll had been looking at the speaker, but dropped his eyes at this point.] In that case he would retain the knife in his possession, not daring to offer it for sale, or for pledge in a pawn-shop. [There was a nodding of heads among the audience by way of admission that this was not a bad stroke.] I shall prove to the satisfaction of the jury that there was a person in Judge Driscoll’s room several minutes before the accused entered it. [This produced a strong sensation; the last drowsy-head in the court-room roused up, now, and made preparation to listen.] If it shall seem necessary, I will prove by the Misses Clarkson that they met a veiled person—ostensibly a woman—coming out of the back gate a few minutes after the cry for help was heard. This person was not a woman, but a man dressed in woman’s clothes.” Another sensation. Wilson had his eye on Tom when he hazarded this guess, to see what effect it would produce. He was satisfied with the result, and said to himself, “It was a success—he’s hit!”
“The object of that person in that house was robbery, not murder. It is true that the safe was not open, but there was an ordinary tin cash-box on the table, with three thousand dollars in it. It is easily supposable that the thief was concealed in the house; that he knew of this box, and of its owner’s habit of counting its contents and arranging his accounts at night—if he had that habit, which I do not assert, of course;—that he tried to take the box while its owner slept, but made a noise and was seized, and had to use the knife to save himself from capture; and that he fled without his booty because he heard help coming.
“I have now done with my theory, and will proceed to the evidences by which I propose to try to prove its soundness.” Wilson took up several of his strips of glass. When the audience recognized these familiar mementoes of Pudd’nhead’s old-time childish “puttering” and folly, the tense and funereal interest vanished out of their faces, and the house burst into volleys of relieving and refreshing laughter, and Tom chirked up and joined in the fun himself; but Wilson was apparently not disturbed. He arranged his records on the table before him, and said—
“I beg the indulgence of the court while I make a few remarks in explanation of some evidence which I am about to introduce, and which I shall presently ask to be allowed to verify under oath on the witness stand. Every human being carries with him from his cradle to his grave certain physical marks which do not change their character, and by which he can always be identified—and that without shade of doubt or question. These marks are his signature, his physiological autograph, so to speak, and this autograph can not be counterfeited, nor can he disguise it or hide it away, nor can it become illegible by the wear and mutations of time. This signature is not his face—age can change that beyond recognition; it is not his hair, for that can fall out; it is not his height, for duplicates of that exist; it is not his form, for duplicates of that exist also, whereas this signature is each man’s very own—there is no duplicate of it among the swarming populations of the globe! [The audience were interested once more.]
“This autograph consists of the delicate lines or corrugations with which Nature marks the insides of the hands and the soles of the feet. If you will look at the balls of your fingers,—you that have very sharp eyesight,—you will observe that these dainty curving lines lie close together, like those that indicate the borders of oceans in maps, and that they form various clearly defined patterns, such as arches, circles, long curves, whorls, etc., and that these patterns differ on the different fingers. [Every man in the room had his hand up to the light, now, and his head canted to one side, and was minutely scrutinizing the balls of his fingers; there were whispered ejaculations of ‘Why, it’s so—I never noticed that before!’] The patterns on the right hand are not the same as those on the left. [Ejaculations of ‘Why, that’s so, too!’] Taken finger for finger, your patterns differ from your neighbor’s. [Comparisons were made all over the house—even the judge and jury were absorbed in this curious work.] The patterns of a twin’s right hand are not the same as those on his left. One twin’s patterns are never the same as his fellow-twin’s patterns—the jury will find that the patterns upon the finger-balls of the accused follow this rule. [An examination of the twins’ hands was begun at once.] You have often heard of twins who were so exactly alike that when dressed alike their own parents could not tell them apart. Yet there was never a twin born into this world that did not carry from birth to death a sure identifier in this mysterious and marvelous natal autograph. That once known to you, his fellow-twin could never personate him and deceive you.”
Wilson stopped and stood silent. Inattention dies a quick and sure death when a speaker does that. The stillness gives warning that something is coming. All palms and finger-balls went down, now, all slouching forms straightened, all heads came up, all eyes were fastened upon Wilson’s face. He waited yet one, two, three moments, to let his pause complete and perfect its spell upon the house; then, when through the profound hush he could hear the ticking of the clock on the wall, he put out his hand and took the Indian knife by the blade and held it aloft where all could see the sinister spots upon its ivory handle; then he said, in a level and passionless voice—
“Upon this haft stands the assassin’s natal autograph, written in the blood of that helpless and unoffending old man who loved you and whom you all loved. There is but one man in the whole earth whose hand can duplicate that crimson sign,”—he paused and raised his eyes to the pendulum swinging back and forth,—“and please God we will produce that man in this room before the clock strikes noon!”
Stunned, distraught, unconscious of its own movement, the house half rose, as if expecting to see the murderer appear at the door, and a breeze of muttered ejaculations swept the place. “Order in the court!—sit down!” This from the sheriff. He was obeyed, and quiet reigned again. Wilson stole a glance at Tom, and said to himself, “He is flying signals of distress, now; even people who despise him are pitying him; they think this is a hard ordeal for a young fellow who has lost his benefactor by so cruel a stroke—and they are right.” He resumed his speech:
“For more than twenty years I have amused my compulsory leisure with collecting these curious physical signatures in this town. At my house I have hundreds upon hundreds of them. Each and every one is labelled with name and date; not labelled the next day or even the next hour, but in the very minute that the impression was taken. When I go upon the witness stand I will repeat under oath the things which I am now saying. I have the finger-prints of the court, the sheriff, and every member of the jury. There is hardly a person in this room, white or black, whose natal signature I cannot produce, and not one of them can so disguise himself that I cannot pick him out from a multitude of his fellow-creatures and unerringly identify him by his hands. And if he and I should live to be a hundred I could still do it. [The interest of the audience was steadily deepening, now.]
