Reggie sat on the edge of the bath. “Well, well, I wouldn’t say that,” he said mildly. “It’s not what we could wish, Bell. But there are points—there are points.”

“All right, sir. Call Mr. Fortune,” Bell grinned.

“I don’t say it’ll ever go into court. But some things we do know. The dead man is Rand, the elusive Rand. He had papers worth burning. He was killed by a powerful man with one or two blows, probably in the sitting-room. After death he was stripped and dressed in the unmarked clothes, probably here. For his body was brought where a mess could be cleaned up, to have the face smashed in. You can see the dents in the linoleum where his head lay. And then he was pitched out by that window. There’s a bit of animal matter, probably human tissue, on that scrap of wood. Then the slayer packed up everything that was bloody and went off; and one of ’em—the tidy slayer or the elusive Rand—one of ’em used cocaine.”

Superintendent Bell shrugged his shoulders. “It don’t take us very far, sir, does it? It don’t amount to so much. What I should call a baffling case. I mean to say, we don’t seem to get near anybody.”

Reggie grunted, got off the bath, and taking with him his bit of wood, went back to the sitting-room, the two detectives in silent attendance. There he tumbled Mr. Rand’s cigarettes out of their box, and put his bit of wood in it.

“I suppose there’s nothing more here,” he murmured, his eyes wandering round the room. “Try it with the lights on. Switch on, inspector. . . . No. Ah, what’s that?” He went to the gas fire and picked out of its lumps of sham coal a scrap of gleaming metal. The next moment he was down on his knees, pulling the fire to pieces. “Give me an envelope, will you?” he said over his shoulder, and they saw he was collecting scraps of broken glass.

“What is it, sir?”

“That’s the bridge of a pair of rimless eyeglasses. And if we’re lucky we can reconstruct the lenses. When Rand was hit, his glasses jumped off and smashed themselves. That’s the fourth thing the slayer didn’t think of.”

“You don’t miss much, Mr. Fortune. Still, it is baffling, very baffling. Even now, we don’t know anybody, so to speak. We don’t even know Rand. What was Rand, would you say? It was worth somebody’s while to do him in. I suppose he knew something. But what did he know? Who was Rand?”

Reggie was putting on his overcoat. He collected his envelope and his cigarette box and put them away, looking the while with dreamy eyes at Superintendent Bell. “Yes,” he said; “yes, there’s a lot of unknown quantities about just now. Who the devil was Rand? Well, well! I think that finishes us here. Will you ring for the lift, inspector?” When he was left alone with Bell, he still gazed dreamily at that plump, stolid face. “Yes. Who the devil was Rand? And if you come to that, who the devil is Sandford?”
