A New York Times bestseller: “Brunetti amply displays the keen intelligence and wry humor that has endeared this series to so many.” — Publishers Weekly   Commissario Brunetti’s latest assignment is to look into a minor shop-keeping violation committed by the mayor’s future daughter-in-law. Brunetti has no interest in helping his boss amass political favors, but has little choice but to comply. Then Brunetti’s wife comes to him with a request of her own. The sweet, simple-minded man who worked at their dry cleaner has just died of a sleeping pill overdose, and Paola loathes the idea that he lived and died without anyone noticing him, or helping him.   Brunetti begins to investigate and is surprised when he finds nothing on the man: no birth certificate, no passport, no driver’s license, no credit cards. As far as the Italian government is concerned, he never existed. Stranger still, the dead man’s mother refuses to speak to the police. And as secrets unravel, Brunetti begins to suspect that an aristocratic family might be somehow connected to the mystery . . .   “Leon’s success . . . is testament to the heartening fact that character counts in crime fiction.” — Booklist , starred review
