for observations. She forecasts the future in gray. Most women of Mrs. Drabdump’s class would have behaved as she did. She happened to be a peculiarly favorable specimen for working on by ‘suggestion,’ but I would have undertaken to produce the same effect on almost any woman under similar conditions. The only uncertain link in the chain was: Would Mrs. Drabdump rush across to get me to break open the door? Women always rush for a man. I was well-nigh the nearest, and certainly the most authoritative man in the street, and I took it for granted she would.”
“But suppose she hadn’t?” the Home Secretary could not help asking.
“Then the murder wouldn’t have happened, that’s all. In due course Arthur Constant would have awoke, or somebody else breaking open the door would have found him sleeping; no harm done, nobody any the wiser. I could hardly sleep myself that night. The thought of the extraordinary crime I was about to commit—a burning curiosity to know whether Wimp would detect the modus operandi—the prospect of sharing the feelings of murderers with whom I had been in contact all my life without being in touch with the terrible joys of their inner life—the fear lest I should be too fast asleep to hear Mrs. Drabdump’s knock—these things agitated me and disturbed my rest. I lay tossing on my bed, planning every detail of poor Constant’s end. The hours dragged slowly and wretchedly on toward the misty dawn. I was racked with suspense. Was I to be disappointed after all? At last the welcome sound came—the rat-tat-tat of murder. The echoes of that knock are yet in my ear. ‘Come over and kill him!’ I put my night-capped head out of the window and told her to wait for me. I dressed hurriedly, took my razor, and went across to 11 Glover Street. As I broke open the door of the bedroom in which Arthur Constant lay sleeping, his head resting on his hands, I cried, ‘My God!’ as if I saw some awful vision. A mist as of blood swam before Mrs. Drabdump’s eyes. She cowered back, for an instant (I divined rather than saw the action) she shut off the dreaded sight with her hands. In that instant I had made my cut—precisely, scientifically—made so deep a cut and drew out the weapon so sharply that there was scarce a drop of blood on it; then there came from the throat a jet of blood which Mrs. Drabdump, conscious only of the horrid gash, saw but vaguely. I covered up the face quickly with a handkerchief to hide any convulsive distortion. But as the medical evidence (in this detail accurate) testified, death was instantaneous. I pocketed the razor and the empty sulfonal phial. With a woman like Mrs. Drabdump to watch me, I could do anything I pleased. I got her to draw my attention to the fact that both the windows were fastened. Some fool, by the by, thought there was a discrepancy in the evidence because the police found only one window fastened, forgetting that, in my innocence, I took care not to fasten the window I had opened to call for aid. Naturally I did not call for aid before a considerable time had elapsed. There was Mrs. Drabdump to quiet, and the excuse of making notes—as an old hand. My object was to gain time. I wanted the body to be fairly cold and stiff before being discovered, though there was not much danger here; for, as you saw by the medical evidence, there is no telling the time of death to an hour or two. The frank way in which I said the death was very recent disarmed all suspicion, and even Dr. Robinson was unconsciously worked upon, in adjudging the time of death, by the knowledge (query here, Mr. Templeton) that it had preceded my advent on the scene.
“Before leaving Mrs. Drabdump there is just one point I should like to say a word about. You have listened so patiently, sir, to my lectures on the science of sciences that you will not refuse to hear the last. A good deal of importance has been attached to Mrs. Drabdump’s oversleeping herself by half an hour. It happens that this (like the innocent fog which has also been made responsible for much) is a purely accidental and irrelevant circumstance. In all works on inductive logic it is thoroughly recognized that only some of the circumstances of a phenomenon are of its essence and causally interconnected; there is always a certain proportion of heterogeneous accompaniments which have no intimate relation whatever with the phenomenon. Yet so crude is as yet the comprehension of the science of evidence, that every feature of the phenomenon under investigation is made equally important, and sought to be linked with the chain of evidence. To attempt to explain everything is always the mark of the tyro. The fog and Mrs. Drabdump’s oversleeping herself were mere accidents. There are always these irrelevant accompaniments, and the true scientist allows for this element of (so to speak) chemically unrelated detail. Even I never counted on the unfortunate series of accidental phenomena which have led to Mortlake’s implication in a network of suspicion. On the other hand, the fact that my servant Jane, who usually goes about ten, left a few minutes earlier on the night of December 3d, so that she didn’t know of Constant’s visit, was a relevant accident. In fact, just as the art of the artist or the editor consists largely in knowing what to leave out, so does the art of the scientific detector of crime consist in knowing what details to ignore. In short, to explain everything is to explain too much. And too much is worse than too little. To return to my experiment. My success exceeded my wildest dreams. None had an inkling of the truth. The insolubility of the Big Bow Mystery teased the acutest minds in Europe and the civilized world. That a man could have been murdered in a thoroughly inaccessible room savored of the ages of magic. The redoubtable Wimp, who had been blazoned as my successor, fell back on the theory of suicide. The mystery would have slept till my death, but—I fear—for my own ingenuity. I tried to stand outside myself, and to look at the crime with the eyes of another, or of my old self. I found the work of art so perfect as to leave only one sublimely simple solution. The very terms of the problem were so inconceivable that, had I not been the murderer, I should have suspected myself, in conjunction of course with Mrs. Drabdump. The first persons to enter the room would have seemed to me guilty. I wrote at once (in a disguised hand and over the signature of ‘One Who Looks Through His Own Spectacles’) to the ‘Pell Mell Press’ to suggest this. By associating myself thus with Mrs. Drabdump I made it difficult for people to dissociate the two who entered the room together. To dash a half-truth in the world’s eyes is the surest way of blinding it altogether. This letter of mine I contradicted myself (in my own name) the next day, and in the course of the long letter which I was tempted to write I adduced fresh evidence against the theory of suicide. I was disgusted with the open verdict, and wanted men to be up and doing and trying to find me out. I enjoyed the hunt more. Unfortunately, Wimp, set on the chase again by my own letter, by dint of persistent blundering, blundered into a track which—by a devilish tissue of coincidences I had neither foreseen nor dreamt of—seemed to the world the true. Mortlake was arrested and condemned. Wimp had apparently crowned his reputation. This was too much. I had taken all this trouble merely to put a feather in Wimp’s cap, whereas I had expected to shake his reputation by it. It was bad enough that an innocent man should suffer; but that Wimp should achieve a reputation he did not deserve, and overshadow all his predecessors by dint of a colossal mistake, this seemed to me intolerable. I have moved heaven and earth to get the verdict set aside and to save the prisoner; I have exposed the weakness of the evidence; I have had the world searched for the missing girl; I have petitioned and agitated. In vain. I have failed. Now I play my last card. As the overweening Wimp could not be allowed to go down to posterity as the solver of this terrible mystery, I decided that the condemned man might just as well profit by his exposure. That is the reason I make the exposure tonight, before it is too late to save Mortlake.”
“So that is the reason?” said the Home Secretary with a suspicion of mockery in his tones.
“The sole reason.”
Even as he spoke a deeper roar than ever penetrated the study. The crowd had again started cheering. Impatient as the watchers were, they felt that no news was good news. The longer the interview accorded by the Home Secretary to the chairman of the Defense Committee, the greater the hope his obduracy was melting. The idol of the people would be saved, and “Grodman” and “Tom Mortlake” were mingled in the exultant plaudits.
“Templeton,” said the Minister, “have you got down every word of Mr. Grodman’s confession?”
“Every word, sir.”
“Then bring in the cable you received just as Mr. Grodman entered the house.”
Templeton went back into the outer room and brought
