It came in a plain brown wrapper, no return address - an audiocassette recording of a horrifying, soul-lacerating scream, followed by the sound of a childlike voice delivering the enigmatic and haunting message: . Bad love. Bad love. Don't give me the bad love... For Alex Delaware, the chant, repeated over and over like a twisted nursery rhyme, is the first intimation that he is about to enter a living nightmare. Others soon follow: disquieting laughter echoing over a phone line that suddenly goes dead, a chilling trespass outside his home in the middle of the night, a sickening act of vandalism. He has becoine the target of a carefully orchestrated campaign of vague threats and intimidation rapidly building to a crescendo as harassment turns to terror, mischief to madness. Searching his memory for the phrase bad love, Alex recalls a symposium he attended over a decade ago commemorating the work of Dr. Andres de Bosch, the celebrated child psychologist who ran a clinic for troubled adolescents. With the help of his friend LAPD detective Milo Sturgis, Alex discovers a seemingly random series of violent deaths - a hit-and-run, a suicidal leap from a high rise, and a brutal mutilation-murder - that may somehow be related to de Bosch. As he delves deeper into the history of the clinic, the escalating pattern of violence becomes inescapably clear. And if Alex fails to decipher the twisted logic of the stalker's mind games, he will be the next to die. Taut, penetrating, terrifying, Bad Love is vintage Kellerman.

When the phone rings in the middle of the night, child psychologist Alex Delaware does not hesitate. Driving through the dream-lit San Fernando Valley, Alex rushes to Jamey Cadmus, the patient he had failed five years before—and who now calls with a bizarre cry for help. But by the time Alex reaches Canyon Oaks Psychiatric Hospital, Jamey is gone, surfacing a day later in the hands of the police, who believe Jamey is the infamous Lavender Slasher, a psychotic serial killer. Wooed by a high-powered attorney to build a defense, Alex will get a chance to do what he couldn’t five years ago. And when he peers into a family’s troubled history and Jamey’s brilliant, tormented mind, the psychologist puts himself at the heart of a high-profile case. Because Alex knows that in a realm of money, loss, and madness, something terrible pushed Jamie over the edge—or else someone is getting away with murder.

With scores of millions of books in print, translation into two dozen languages, and one of the most popular heroes in contemporary fiction to his name, #1 New York Times bestselling author Jonathan Kellerman is the unequivocal “master of the psychological thriller” (People). In his newest novel Kellerman delivers a tour de force–poignant, dark, and chilling–that illuminates a shadowy world where impulse rules. Tanya Bigelow was a solemn little girl when Dr. Alex Delaware successfully treated her obsessive-compulsive symptoms. Now, at nineteen, she still seems older than her years–but her problems go beyond hyper-maturity. Patty Bigelow, Tanya’s aunt and adoptive mother, has made a deathbed confession of murder and urged the young woman to seek Delaware’s help. The doctor recalls Patty as a selfless E.R. nurse struggling to raise a child on her own–a woman seemingly incapable of the “terrible thing” she has admitted. But for Tanya’s peace of mind, Delaware agrees to investigate, and he enlists LAPD detective Milo Sturgis in the search for the phantom victim of a crime that may never have occurred. Armed with only the vaguest details, psychologist and cop follow a trail twisting from L.A.’s sleaziest low-rent districts to its overblown mansions, retracing Patty and Tanya’s nomadic and increasingly puzzling life to the doorsteps of a sullen heroin addict; a randy real-estate broker; and a brilliant, enigmatic physics student. Suddenly a very real murder tears open a terrifying tunnel into the past, where secrets–and bodies–are buried. As the tension mounts, Delaware and Sturgis uncover a tangled history of desperation, vengeance, and death–a legacy of evil that refuses to die. Dramatic, action-packed, and filled with the psychological detail that only Jonathan Kellerman can provide, Obsession is a whodunit, a whydunit–and something unique: a did-it-even-happen? This is Kellerman at his heart-racing best. From the Hardcover edition.
