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 inclosed 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 match-box 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.
CHAPTER II
NUMBER SEVEN IN THE SQUARE
Before the sputter of the match had died out, Viner had recognized the man who lay dead at his feet. He was a man about whom he had recently felt some curiosity, a man who, a few weeks before, had come to live in a house close to his own, in company with an elderly lady and a pretty girl; Viner and Miss Penkridge had often seen all three in and about Markendale Square, and had wondered who they were. The man looked as if he had seen things in life—a big, burly, bearded man of apparently sixty years of age, hard, bronzed; something about him suggested sun and wind as they are met with in the far-off places. Usually he was seen in loose, comfortable, semi-nautical suits of blue serge; there was a roll in his walk that suggested the sea. But here, as he lay before Viner, he was in evening dress, with a light overcoat thrown over it; the overcoat was unbuttoned and the shirt-front exposed. And on it that sickening crimson stain widened and widened as Viner watched.
Here, without doubt, was murder, and Viner's thoughts immediately turned to two things—one the hurrying young man whose face he thought he had remembered in some vague fashion; the other the fact that a policeman was slowly pacing up the terrace close by. He turned and ran swiftly up the still deserted passage. And there was the policeman, twenty yards away, coming along with the leisureliness of one who knows that he has a certain area to patrol. He pulled himself to an attitude of watchful attention as Viner ran up to him; then suddenly recognizing Viner as a well-known inhabitant of the Square, touched the rim of his helmet.
"I say!" said Viner in the hushed voice of one who imparts strange and confidential tidings. "There's a man lying dead in the passage round here. And without doubt murdered! There's blood all over his shirt-front."
The policeman stood stock still for the fraction of a second. Then he pulled out his whistle and blew loudly and insistently. Before the shrill call had died away, he was striding towards the passage, with Viner at his side.
"Did you find him, Mr. Viner?" he asked.
"I found him," asserted Viner. "Just now—halfway down the passage!"
