Cain, Chelsea Archie Sheridan & Gretchen Lowell Series

Books 1-6

Portland detective Archie Sheridan spent years tracking Gretchen Lowell, a beautiful and brutal serial killer known as the Beauty Killer. In the end, she was the one who caught him…and tortured him…and then let him go.

Why did Gretchen spare Archie’s life and then turn herself in? This question keeps him up all night—and keeps him coming back to visit Gretchen in prison every week. But Archie also needs Gretchen, as new murder cases he’s solving keep leading him back to his former captor.
