"You made a bad break that time" Grim was in Mephistophelian humor.

He can sleep cat-fashion, for sixty seconds at a time, with all his wits about him in the intervals, and likes to feel in the crook of his own forefinger the hidden hair-trigger of events.

I don't think Jeremy was awake when I first entered the room, although it suited Grim's humor that he should be presently; but you would have sworn they were both unconscious, judging by the see-saw, bass and baritone snoring.
I poured out whisky, drank a little of it grouchily, and watched Yussuf Dakmar into bed.

He didn't take many of his clothes off and even by candle-light you could see the shape of the knife concealed under his shirt.

He sat cross-legged on the bed, presumably praying, and as I didn't like the look of him I blew out the candle.
Instantly, pinched and prompted by James Schuyler Grim, Jeremy sat up and yammered profanely at the darkness, vowing he couldn't see to sleep without a light in the room.
