Set in the Valley of an unnamed Western state, Quinn's winning debut introduces one smart canine detective and his partner, PI Bernie Little of the Little Detective Agency, who's pretty quick on the uptake himself. Chet, a lively mongrel with one white ear and one black ear, serves as the book's narrator, communicating with Bert via doggy methods that verge on the telepathic (I wagged my tail, that quick one-two wag meaning yes, not the over-the-top one that wags itself and can mean lots of things). Wealthy divorcée Cynthia Chambliss hires Bernie, a former cop, to find her missing 15-year-old daughter, Madison, whose father is a real estate developer who smells suspiciously of cat. (Chet's keen sense of smell comes in handy.) When Madison reappears and disappears again, her dad says she's just a runaway, though Bernie thinks otherwise. Chet must use all his superdog tricks to extricate Bernie from a mighty tight fix in a climax that fans of classic mysteries are sure to appreciate.
