Motive : an Alex Delaware novel / Jonathan Kellerman.

"The #1 New York Times bestselling author 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 divorcee 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 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"--

Turns out her devoted boyfriend has an alibi and, with few clues leading to a suspect, LAPD's Lieutenant Milo Sturgis calls in psychologist Alex Delaware for help. Then another woman's shot execution style; three bullets in the back of her head leave her husband with a profitable business. He's got an alibi too. As the body count builds, Alex and Milo make the horrible realization that they're dealing with a diabolically manipulative killer intent on playing the most twisted and bloodiest kind of game with the cops -- and with Milo, specifically"--
