The Torment of Others:
In a small grim room, the body of a woman is discovered, panic and pain etched in her face. The scene matches in every detail a series of murders two years ago-murders that ended when irrefutable forensic evidence secured the conviction of a deeply disturbed young man named Derek Tyler.

But there's no way Tyler could have killed the latest victim. He's been locked up in a mental institution since his trial, barely speaking a word. So is there a copycat?...

All his years of experience tell top criminal psychologist Dr. Tony Hill that there isn't-but that would make the murders literally impossible. While Hill tries to crack Tyler, DCI Carol Jordan and her team must mount a desperate undercover operation to trap the murderer-a decision that will have terrible consequences.

The Mermaids Singing:
This was the summer he discovered what he wanted--at a gruesome museum of criminology far off the beaten track of more timid tourists. Visions of torture inspired his fantasies like a muse. It would prove so terribly fulfilling.

The bodies of four men have been discovered in the town of Bradfield. Enlisted to investigate is criminal psychologist Tony Hill. Even for a seasoned professional, the series of mutilation sex murders is unlike anything he's encountered before. But profiling the psychopath is not beyond him. Hill's own past has made him the perfect man to comprehend the killer's motives. It's also made him the perfect victim.

A game has begun for the hunter and the hunted. But as Hill confronts his own hidden demons, he must also come face-to-face with an evil so profound he may not have the courage--or the power--to stop it..
