The Murder of Roger Ackroyd, by Agatha Christie

Retired from the Brussels police force, M. Hercule Poirot has settled into obscurity in a sleepy little English town--but when a wealthy local man turns up murdered, he is not exactly reluctant to get back into detective work.

I admit I did not guess whodunnit. I had to wait like everyone else gathered in the parlor to learn the identity of the killer.

Christie eventually tired of Poirot, but the public clamored for him. He is eccentric and pompous, with quite a high opinion of himself, but justifiably so. I don't feel moved to read the Miss Marple books, but I think I'll read some more Poirot mysteries. I recommend the audiobook narration by Hugh Fraser (who played Captain Hastings to David Suchet's Poirot).
