Her body floats. A bloated thing half atop the river. Naked. Pale. Mouth and eyes open wide. When two fishermen discover a corpse floating in the Clackamas river, profiler Violet Darger heads to rural Oregon to hunt another serial killer. What she discovers in the woods might change the course of her life. What secrets does the water conceal? The girl in the water marks the third such case in the area - all drowned with superficial stab wounds and discovered in a body of water - and Darger feels certain she won't be the last. The corpses are badly decomposed.

Special Agent Violet Darger must make sense of this savagery - figure out how brutality like this could happen in rural Michigan. The victim had been living the American dream. A small-business owner who built a construction empire. Started a family. Coached youth hockey. He seemed to have it all. But his surface life didn’t tell the full story. He carried dark secrets to the grave. Left clues which offer more questions than answers, clues that seem to lead Darger to Detroit.

Thousands of girls go missing every year in Las Vegas. Taken. Bought and sold. Or worse. These lost girls summon FBI Profiler Violet Darger to Sin City. There are fresh dead to sort through - two bodies burned beyond recognition in the trunk of a sedan - and there’s reason to believe there are missing girls waiting to be saved. Rumors swirl that a legendary killer is responsible for these crimes: an escaped prisoner with a personal grudge against Darger. One who disappeared for 20 years. If Darger finds the killer in time, the girls will live. If not...

A serial killer stalks women in rural Ohio. He is deranged but brilliant, known only by the grotesque nickname the media has given him - The Doll Parts Killer. The name is apt. He dismembers his victims and leaves them in garbage bags in public places. A residential neighborhood. Next to a roller rink. Behind a Burger King. The investigation is a disaster. No physical evidence. Unreliable witnesses. To make matters worse, the FBI has lost contact with the star profiler working the case.

Two days. Fourteen dead. The next victim could be you. The first bullet punches through the windshield of an SUV. A head shot. The driver's death is instantaneous. And it's only the beginning. A sniper along I-20 kills eight and causes a 36 car pileup. Brutal. Efficient. The next morning, the same individual stalks through a grocery store parking lot with a handgun. He takes out six innocent shoppers along with the store's front window before fleeing without a trace.

Some secrets don’t stay buried. Three elaborately staged victims. No clues. A public verging on panic. FBI profiler Victor Loshak heads to Kansas City to hunt another serial killer. But something about this case is all wrong. The three corpses lie posed. Face up. A glove laid to cover each right eye. The victims seem to be selected at random. Suburban. Upper middle class. Squeaky clean. It doesn’t make sense. A piece is missing from this puzzle.

When a cold, naked body is discovered by a couple on a jog through the lush woodlands of Pine Valley, California, new recruit Detective Katie Scott is stunned to discover the victim is Amanda Payton - a much-loved local nurse and the woman at the heart of an unsolved case she’s been investigating whilst getting a grip on her crippling PTSD.

The Pine Valley police made a fatal mistake....

In the remote forests of Stillwater, Minnesota, you can scream for days and no one will hear you. So when the bodies of two 15-year-old girls are discovered frozen in the snow, Special Agent Nikki Hunt is sure the killer is local: Someone knew where to hide the girls and thought they would never be found. Though Nikki hasn’t been home in 20 years, she knows she must take over the case.
