"The man you sent here to-day."

"I don't know what you mean."

"Oh come, that won't do. Anyhow he does, and that's enough for me." I tried to pop in the suggestion of a threat.

"What's his name?"

"You know that without my telling you; I only know what he called himself. You don't send men about the place on secret errands without knowing their names, do you?"

"Well, what does he call himself?"

"Rudolff; I don't know who he is now."

"I never heard of the man, and I've had enough of your tomfoolery."

"Just as you like. I can deal with him, of course." I heard him swear sulphurously.

"What does he want?" he growled after a pause.
