I've been reading The Widow's Son. The novel features a police captain, named Loup-Garou, who carries out all of his orders without questioning them. "He never wondered for a moment if this Signor Celine had done anything wrong, or deserved what was about to happen to him ... " (Chapter Eight.)
The character's name bothered me until I finally looked it up and discovered that it means "wolf." No doubt there are many other jokes in the text that I've missed.
Update: It actually means "werewolf." Thanks to Supergee for the correction in the comment below.
