November though it was the night was fine and clear, and there was a half-moon in the heavens; also there was rather more than a suspicion of frost in the air, and the stars, accordingly, wore a more brilliant appearance. To one who loved night strolling, as Viner did, this was indeed an ideal night for the time of year; and on this occasion, therefore, he went further than usual going along Bayswater Road as far as Notting Hill Gate, and thence returning through the various streets and terraces which lay between Pembridge Gardens and Markendale Square. And while he strolled along, smoking his pipe, watching the twinkling lights of passing vehicles and enjoying the touch of frost, he was thinking, in a half-cynical, half-amused way, of his Aunt Bethia’s taste for the sensational fiction and of her evidently sincere conviction that there were much stranger things in real life than could be found between the covers of any novel.
“Those were certainly two very odd instances which she gave me,” he mused, “those of the prosperous banker and the pretty bride. In the first, how on earth did the man contrive to get away unobserved from a town in which, presumably, every soul knew him? Why did he go? Did he go? Is his body lying at the bottom of some hole by some roadside? Was he murdered in broad daylight on a public road? Did he lose his reason or his memory, and wander away and away? I think, as my aunt sagely remarked, that nobody is ever going to find anything about that affair! Then my Lady Marshflower—there’s a fine mystery! Who was the man? What did she know about him? Where had they met? Had they ever met? Why did he shoot her? How on earth did he contrive to disappear without leaving some trace? How—”
At this point Viner’s musings and questionings were suddenly and rudely interrupted. Unconsciously he had walked back close to his own Square, but on the opposite side to that by which he had left it, approaching it by one of the numerous long terraces which run out of the main road in the Westbourne Grove district—when his musings were rudely interrupted. Between this terrace and Markendale Square was a narrow passage, little frequented save by residents, or by such folk familiar enough with the neighbourhood to know that it afforded a shortcut. Viner was about to turn into this passage, a dark affair set between high walls, when a young man darted hurriedly out of it, half collided with him, uttered a hasty word of apology, ran across the road and disappeared round the nearest corner. But just there stood a street-lamp, and in its glare Viner caught sight of the hurrying young man’s face. And when the retreating footsteps had grown faint, Viner still stood staring in the direction in which they had gone.
“That’s strange!” he muttered. “I’ve seen that chap somewhere—I know him. Now, who is he? And what made him in such a deuce of a hurry?”
It was very quiet at that point. There seemed to be nobody about. Behind him, far down the long, wide terrace, he heard slow, measured steps—that, of course, was a policeman on his beat. But beyond the subdued murmur of the traffic in the Bayswater Road in one direction and in Bishop’s Road, Viner heard nothing but those measured steps. And after listening to them for a minute, he turned into the passage out of which the young man had just rushed so unceremoniously.
There was just one lamp in that passage—an old-fashioned affair, fixed against the wall, halfway down. It threw but little light on its surroundings. Those surroundings were ordinary enough. The passage itself was about thirty yards in length. It was enclosed on each-side by old brick walls, so old that the brick had grown black with age and smoke. These walls were some fifteen feet in height; here and there they were pierced by doors—the doors of the yards at the rear of the big houses on either side. The doors were set flush with the walls—Viner, who often walked through that passage at night, and who had something of a whimsical fancy, had thought more than once that after nightfall the doors looked as if they had never been opened, never shut. There was an air of queer, cloistral or prisonlike security in their very look. They were all shut now, as he paced down the passage, as lonely a place at that hour as you could find in all London. It was queer, he reflected, that he scarcely ever remembered meeting anybody in that passage.
And then he suddenly paused, pulling himself up with a strange consciousness that at last he was to meet something. Beneath the feeble light of the one lamp Viner saw a man. Not a man walking, or standing still, or leaning against the wall, but lying full length across the flagged pavement, motionless—so motionless that at the end of the first moment of surprise, Viner felt sure that he was in the presence of death. And then he stole nearer, listening, and looked down, and drawing his matchbox from his pocket added the flash of a match to the poor rays from above. Then he saw white linen, and a bloodstain slowly spreading over its glossy surface.
