L.H.S. (to the House): "My lords, your lordships will, of course, use your own judgment as to the value of this suggestion."
Counsel: "If your lordships can accept that Denis Cathcart may have known of the existence of the revolver, it is immaterial at what exact moment he saw it. As you have heard, the table-drawer was always left with the key in it. He might have seen it himself at any time, when searching for an envelope or sealing-wax or what not. In any case, I contend that the movements heard by Colonel and Mrs. Marchbanks on Wednesday night were those of Denis Cathcart. While he was writing his farewell letter, perhaps with the pistol before him on the table—yes, at that very moment the Duke of Denver slipped down the stairs and out through the conservatory door. Here is the incredible part of this affair—that again and again we find two series of events, wholly unconnected between themselves, converging upon the same point of time, and causing endless confusion. I have used the word 'incredible'—not because any coincidence is incredible, for we see more remarkable examples every day of our lives than any writer of fiction would dare to invent—but merely in order to take it out of the mouth of the learned Attorney-General, who is preparing to make it return, boomerang-fashion, against me. (Laughter.)
"My lords, this is the first of these incredible—I am not afraid of the word—coincidences. At 11:30 the Duke goes downstairs and Cathcart enters the study. The learned Attorney-General, in his cross-examination of my noble client, very justifiably made what capital he could out of the discrepancy between witness's statement at the inquest—which was that he did not leave the house till 2:30—and his present statement—that he left it at half-past eleven. My lords, whatever interpretation you like to place upon the motives of the noble Duke in so doing, I must remind you once more that at the time when that first statement was made everybody supposed that the shot had been fired at three o'clock, and that the misstatement was then useless for the purpose of establishing an alibi.
"Great stress, too, has been laid on the noble Duke's inability to establish this alibi for the hours from 11:30 to 3 a.m. But, my lords, if he is telling the truth in saying that he walked all that time upon the moors without meeting anyone, what alibi could he establish? He is not bound to supply a motive for all his minor actions during the twenty-four hours. No rebutting evidence has been brought to discredit his story. And it is perfectly reasonable that, unable to sleep after the scene with Cathcart, he should go for a walk to calm himself down.
"Meanwhile, Cathcart has finished his letter and tossed it into the post-bag. There is nothing more ironical in the whole of this case than that letter. While the body of a murdered man lay stark upon the threshold, and detectives and doctors searched everywhere for clues, the normal routine of an ordinary English household went, unquestioned, on. That letter, which contained the whole story, lay undisturbed in the post-bag, till it was taken away and put in the post as a matter of course, to be fetched back again, at enormous cost, delay, and risk of life, two months later in vindication of the great English motto: 'Business as usual.'
"Upstairs, Lady Mary Wimsey was packing her suit-case and writing a farewell letter to her people. At length Cathcart signs his name; he takes up the revolver and hurries out into the shrubbery. Still he paces up and down, with what thoughts God alone knows—reviewing the past, no doubt, racked with vain remorse, most of all, bitter against the woman who has ruined him. He bethinks him of the little love-token, the platinum-and-diamond cat which his mistress gave him for good luck! At any rate, he will not die with that pressing upon his heart. With a furious gesture he hurls it far from him. He puts the pistol to his head.
"But something arrests him. Not that! Not that! He sees in fancy his own hideously disfigured corpse—the shattered jaw—the burst eyeball—blood and brains horribly splashed about. No. Let the bullet go cleanly to the heart. Not even in death can he bear the thought of looking—so!
"He places the revolver against his breast and draws the trigger. With a little moan, he drops to the sodden ground. The weapon falls from his hand; his fingers scrabble a little at his breast.
"The gamekeeper who heard the shot is puzzled that poachers should come so close. Why are they not on the moors? He thinks of the hares in the plantation. He takes his lantern and searches in the thick drizzle. Nothing. Only soggy grass and dripping trees. He is human. He concludes his ears deceived him, and he returns to his warm bed. Midnight passes. One o'clock passes.
"The rain is less heavy now. Look! In the shrubbery—what was that? A movement. The shot man is moving—groaning a little—crawling to his feet. Chilled to the bone, weak from loss of blood, shaking with the fever of his wound, he but dimly remembers his purpose. His groping hands go to the wound in his breast. He pulls out a handkerchief and presses it upon the place. He drags himself up, slipping and stumbling. The handkerchief slides to the ground, and lies there beside the revolver among the fallen leaves.
