Circling high over Rockefeller Center is a peregrine falcon, the most awesome of the flying predators. She awaits a signal from her falconer. It is given: the bird attacks, plummeting from the sky at nearly 200 miles an hour, striking a young woman and killing her instantly.

So begins Peregrine, a chilling tale of obsession.

By chance, newscaster Pamela Barrett witnesses the slaying. Her impassioned account of it on television that evening thrills the falconer, a brilliant madman who identifies with his deadly bird. He becomes fascinated with Pam and enmeshes her in a bizarre and deadly scheme even as she finds herself drawn to him by an erotic need she doesn't understand.

As killing follows killing, the police and the media engage in cutthroat competition to find the murderer. Two falcons fight to the death above Central Park. Call girls, rich eccentrics, dealers in the black market for rare birds--all play their roles in this study of secret passion, desire, fulfillment, and ecstasy.
