"There was blood on the outside of his clothes," Evan told him.

"Someone else's blood." He watched Riley's face closely.

Riley shrugged. "Could be the younger man's, could be someone else's.

I've no way of knowing.”

"What condition is he in now, the younger man? What are his injuries?”

Riley was distressed, he looked overwhelmed by his knowledge as if it were something he would have gladly put down.

"Very bad," he said almost under his breath. "He's still senseless, but definitely alive. If he pulls through tonight he'll need a lot of careful nursing, many weeks, maybe months. He's badly injured internally, but it's hard to tell exactly what. Can't see inside a body without cutting it open. As much as I can feel, the major organs are terribly bruised, but not ruptured. If they were, he'd be dead by now. Luckier than the other man where the blows landed. Both his hands are badly broken, but that hardly matters, compared.”

"Nothing in his clothes to say who he is, I suppose?" Evan asked without any real hope.

"Yes," Riley said quickly, his eyes wide. "Apparently he had a receipt for socks with the name "R. Duff" on it. Must be his. Can't think why you'd carry a receipt for another man's socks! And he has the same tailor as the dead man. There's a very slight physical resemblance about the shape of head, way the hair grows, and particularly the ears.

Do you notice a man's ears, Sergeant Evan? Some people don't. You'd be surprised how many. Ears are very distinctive. I think you might find our two men are related.”

"Duff?" Evan could hardly believe his good fortune. "R. Duff?”

"That's right. No idea what the "R" stands for, but maybe he'll be able to tell us himself tomorrow. Anyway, you can try the tailor in the morning. A man often knows his own handiwork.”
