When a swashbuckling stranger shows up at Count Raimon VI's chateau in May 1205 claiming to be the count's hitherto unknown brother in Gordon's engaging eighth Fools' Guild mystery (after 2008's The Moneylender of Toulouse
), Toulouse's ruler taps one of his court's best minds to investigate—Theophilos the fool. A jester by trade only, Theophilos will need every bit of his considerable wit to solve a conundrum that turns increasingly treacherous after a flame-haired beauty is found slain in her brothel boudoir, the count's putative sibling still asleep beside her. Theophilos will also need crucial assists from his partners in crime solving, including his bewitching wife, Claudia—a duke's daughter equally adept with riposte or rapier—and their scarily precocious 12-year-old apprentice, Helga. With characters as entertaining as these, the long-running appeal of Gordon's series proves no mystery at all. (Jan.)
