Deftly mixing fascinating art history and murder with an exotic atmospheric setting (the Bomarzo garden actually exists), dramatic historical period (1928 fascist Italy), and fully fleshed characters, Lappin (The Etruscan) has written a hallucinatory gothic mystery in which no one is as they appear. Daphne is a most memorable, if a bit unreliable (thanks to her opium habit), narrator. Readers looking for an intelligent summer mystery will find much to savor here.
