Mysterious killings at the Olympique Scientific Internationale (an eminent astronomer, an investigating police officer, an annoying scientist turned amateur sleuth)—committed by what sounds, from the one surviving witness's account, like a werewolf—flush out formidably brainy Niccolo Benedetti and his Nick-and-Nora satellites Ron Gentry and Janet Higgins (The Hog Murders). Despite the hints of the supernatural, this is pure Agatha Christie, with negligible characters, a novel (but unconvincingly evoked) setting, ingenious clues, a most-unlikely-culprit, and a shameless theft of two of Christie's favorite clichÇs of misdirection that shouldn't fool you for a minute. For retro fans, a pleasant enough couple of hours.
