NEW YORK TIMES BESTSELLER   LAPD homicide detective Milo Sturgis summons his friend psychologist-sleuth Alex Delaware to a trendy gallery where a promising young artist has been brutally garroted on the night of her first major showing. The details of the murder scene immediately suggest to Alex not an impulsive crime of passion but the meticulous and taunting modus operandi of a serial killer.   “No one does psychological suspense as well as Jonathan Kellerman.”—Detroit Free Press   Delaware’s suspicions are borne out when he and Milo find a link between the artist’s death and the murder of a noted blues guitarist. The twisting trail leads from halfway houses to palatial mansions, from a college campus to the last place Alex ever expected: the doorstep of his ex-lover Robin Castagna. As more killings are discovered, unraveling the maddening puzzle assumes a chilling new importance—stopping a vicious psychopath who’s made cold-blooded murder his chosen art form.
