Heartsick

2007

Damaged Portland detective Archie Sheridan spent ten years tracking Gretchen Lowell, a beautiful serial killer, but in the end she was the one who caught him. Two years ago, Gretchen kidnapped Archie and tortured him for ten days, but instead of killing him, she mysteriously decided to let him go. She turned herself in, and now Gretchen has been locked away for the rest of her life, while Archie is in a prison of another kind—-addicted to pain pills, unable to return to his old life, powerless to get those ten horrific days off his mind. Archie's a different person, his estranged wife says, and he knows she's right. He continues to visit Gretchen in prison once a week, saying that only he can get her to confess as to the whereabouts of more of her victims, but even he knows the truth—-he can't stay away. When another killer begins snatching teenage girls off the streets of Portland, Archie has to pull himself together enough to lead the new task force investigating the murders. A hungry young newspaper reporter, Susan Ward, begins profiling Archie and the investigation, which sparks a deadly game between Archie, Susan, the new killer, and even Gretchen. They need to catch a killer, and maybe somehow then Archie can free himself from Gretchen, once and for all. Either way, Heartsick makes for one of the most extraordinary suspense debuts in recent memory.

Evil at Heart

2009

Chelsea Cain’s novels featuring Portland detective Archie Sheridan and serial killer Gretchen Lowell have captivated fans through two nail-biting entries, Heartsick and Sweetheart, both of them multiweek bestsellers in The New York Times, USA Today, and Publishers Weekly. Gretchen Lowell is still on the loose. These days, she’s more of a cause célèbre than a feared killer, thanks to sensationalist news coverage that has made her a star. Her face graces magazine covers weekly and there have been sightings of her around the world. Most shocking of all, Portland Herald reporter Susan Ward has uncovered a bizarre kind of fan club, which celebrates the number of days she’s been free. Archie Sheridan hunted her for a decade, and after his last ploy to catch her went spectacularly wrong, remains hospitalized months later. When they last spoke, they entered a détente of sorts—-Archie agreed not to kill himself if she agreed not to kill anyone else. But when a new body is found accompanied by Gretchen’s trademark heart, all bets are off and Archie is forced back into action. Has the Beauty Killer returned to her gruesome ways, or has the cult surrounding her created a whole new evil? Chelsea Cain continues to deliver heart-stopping thrills and chills in the latest entry in this dynamic bestselling series.

Kill You Twice

2012

Nothing makes Portland detective Archie Sheridan happier than knowing that Gretchen Lowell—the serial killer whose stunning beauty is belied by the gruesome murders she's committed—is locked away in a psych ward. Archie can finally heal from the near-fatal physical and emotional wounds she's inflicted on him and start moving on with his life. To this end, Archie throws himself into the latest case to come across his desk: A cyclist has discovered a corpse in Mount Tabor Park on the eastern side of Portland. The man was gagged, skinned, and found hanging by his wrists from a tree. It's the work of a killer bold and clever enough to torture his victim for hours on a sunny summer morning in a big public park and yet leave no trace. And then Archie gets a message he can't ignore—Gretchen claims to have inside knowledge about this grisly murder. Archie finally agrees to visit Gretchen, because he can't risk losing his only lead in the case. At least, that's what he tells himself . . . but the ties between Archie and Gretchen have always been stronger, deeper, and more complex than he's willing to admit, even to himself. What game is she playing this time? And even more frightening, what long-hidden secrets from Gretchen's past have been dredged up that someone would kill to protect? At once terrifying and magnetic, "Beauty Killer" Gretchen Lowell returns with a vengeance in Kill You Twice, Chelsea Cain's latest razor-sharp psychological thriller.
