"Beaten to death," Riley said, pursing his lips. "No wound with any weapon… unless you count fists and boots as weapons. No knife, no gun, no cudgel as far as I can judge. Nothing to the head more than a flat concussion from falling on to the cobbles. Wouldn't have killed him, probably not even knocked him senseless. Probably just stunned and a little dizzy. Died of internal haemorrhage. Ruptured organs.

Sorry.”

"Could one man alone have done that to him?”

Riley thought for quite a long time before he replied, standing still in the middle of the passage, oblivious of blocking the way for others.

"Hard to say. Wouldn't like to commit myself. Taking that body alone, without considering the circumstances, I'd guess more than one assailant. If it was only one man, then he was a raving lunatic to do that to another man. He must have gone berserk.”

"And with considering the circumstances?" Evan pressed, stepping to one side to allow a nurse to pass with a bundle of laundry.

"Well, the boy's still alive, and if he survives tonight, he might recover," Riley answered. "Too soon to say. But to take on both of them, and do that much damage, I'd say two assailants who were both big and well used to violence, or possibly even three. Or else again, two complete lunatics.”

"Could they have fought each other?”

Riley looked surprised. "And left themselves damn near dead on the pavement? Not very likely.”

"But possible?" Evan insisted.

Riley shook his head. "Don't think you'll find the answer is that easy, Sergeant. The younger man is taller. The older one was a bit plump, he was well muscled, quite powerful. He'd have taken a lot of beating, considering he was fighting for his life. And there was no weapon to give the advantage.”

"Can you tell if the wounds were made attacking or defending?”

"Mostly defending, as well as I can judge, but it's only a deduction made from their position, on forearms, as if he were putting up his arms to protect his head. He may have begun by attacking. He certainly landed a few blows, judging from his knuckles. Someone else is going to be badly marked, whether it is anywhere that shows or not.”
