"What, don't you know who he is?" Charles demanded.

"Not yet."

Charles looked round at the others. "I don't believe he's a detective at all. Let's exorcise him. Anyone got any wolfbane, or is that only good against vampires?"

"You needn't pay any attention to Charles," Margaret said. "We never do. Peter didn't see the monk, and I didn't recognise him at all. He never spoke, and the disguise absolutely covered him."

"Just one thing!" Peter said. "There was a button missing from one glove."

Michael's eyes brightened. "So even the Monk slips up occasionally! That's going to be very valuable. You can't tell me anything more about him?"

"No, except that he's about your height," Margaret said, "and very strong."

"I see. I hoped he might have given you some clue to his identity."

"Haven't you got any idea who he is?" Margaret asked.

"I've got a strong suspicion, but that's not quite enough."
