The Wild Imagination of Harry Stephen Keeler. "It’s also interesting to compare him to Agatha Christie, his exact contemporary. I recently read a non-series Christie that I was really enjoying: great voice, realistic atmosphere of doom. I was knocked out. But then I got to the twist, and I felt absolutely cheated by a nonsensical revelation. Certain ground rules had been set and then blithely ignored. Well, with Keeler, there’s a whiff of laughing gas right from the start, so that when, say, a climactic courtroom scene ends with the joint affidavit of…two cats, you feel like you’ve gotten your money’s worth."
Quite, but then I don't care much for Christie.
