In Agatha and Anthony-winner Andrews's fourth wacky bird-themed mystery (Murder with Peacocks, etc.), Meg Langslow, a temporary switchboard operator at her brother Rob's computer-game company, Mutant Wizards, must find the real killer when Rob, who made his fortune from a game called Lawyers from Hell, is accused of strangling the office pest to death with a computer mouse cable. Keeping exposition to a minimum, the author lets crackling dialogue propel the plot. The office boasts a menagerie of remarkable pets, notably George, a buzzard with only one wing who has a perch by Meg's desk. There's a smile on nearly every page and at least one chuckle per chapter. The denouement may stretch credibility, but getting there is such fun it scarcely matters.
