Twisted minds are Margie Reed's business. A skilled forensic psychologist, she's trained to look for deep, dark reasons behind criminal behavior... and now she's found a nightmare. Alone in her apartment, she knows someone is watching. Working in her office, she feels the evil of an unseen enemy close by. Walking to her car, she senses someone following. And then come the flowers. And the warnings. Someone has already killed-for pleasure. Now he wants her to die. One brave cop figures Margie can help him catch this psycho on the loose. But only if she dares to face what's lurking in the shadows...and the secrets hidden in her own aching heart.
