NEW YORK TIMES BESTSELLER Jonathan Kellerman writes razor-sharp novels that cut to the quick. Now comes Motive, which pits psychologist Alex Delaware and homicide cop Milo Sturgis against a vicious criminal mind--the kind only Kellerman can bring to chilling life.   Even having hundreds of closed cases to his credit can't keep LAPD police lieutenant Milo Sturgis from agonizing over the crimes that don't get solved--and the victims who go without justice. Victims like Katherine Hennepin, a young woman strangled and stabbed in her home. A single suspect with a solid alibi leads to a dead end--one even Alex Delaware's expert insight can't explain. The only thing to do is move on to the next murder case--because there's always a next one.   This time the victim is Ursula Corey: a successful, attractive divorcée who's been gunned down--not a robbery but an execution, a crime that smacks of simple, savage revenge. And along with that theoretical motive come two strong contenders for the role of perp: the dead woman's business partner/ex-husband and her divorce lawyer/secret lover. But just as Alex and Milo think they're zeroing in on the most likely suspect, a bizarre new clue stirs up eerie echoes of the unsolved Hennepin murder. And the discovery of yet another crime scene bearing the same taunting signature raises the specter of a serial killer on a mission, whose twisted method is exceeded only by his manipulative and cunning madness. Praise for Motive   "In Kellerman's capable hands, the journey is as much a pleasure as arriving at the destination. There's the interplay between old friends Delaware and Sturgis, the exploration of L.A. environs, and the omnipresent food, which briefly dulls the appetite of even well-padded Sturgis. This thirtieth in the series is one of the best." -- Booklist   "The crafty plot of Edgar-winner Kellerman's thirtieth novel featuring L.A. psychologist Alex Delaware will even keep genre veterans guessing. . . . The twists are both shocking and logical, and the byplay between the leads entertaining." -- Publishers Weekly   Praise for Jonathan Kellerman   "Jonathan Kellerman's psychology skills and dark imagination are a potent literary mix." --Los Angeles Times   "A master of the psychological thriller." --People   "The combination of Alex Delaware [and] Detective Milo Sturgis . . . makes for the most original whodunit duo since Watson and Holmes." --Forbes
