Detective Megan Carpenter is no stranger to evil. Escaping the horrors of her old life, she’s vowed never to let anyone hurt her or those she loves ever again. Joining the small police force in Jefferson County’s Port Townsend, Megan is determined to get every victim of a crime the justice they deserve. So when Ruth Turner walks into the Sheriff’s office claiming her sister Ida Watson has been missing for over a month, Megan’s instincts tell her that she needs to do more than just file a report.

They call it the Bone Box. A collection of old cases, solved and unsolved, that continue to haunt forensic pathologist Birdy Waterman. None is more disturbing than the first. After two decades, Birdy still remembers the screaming. The blood on the boy's hands. The body of a girl, butchered in the woods. Birdy's testimony helped put her own cousin behind bars. It was a sacrifice for what she thought was right - but now, 20 years later, she wants to reopen the box.

The tragic story of Susan Powell and her murdered boys, Charlie and Braden, is the only case that rivals the Jon Benet Ramsey saga in the annals of true crime. When the pretty, blonde Utah mother went missing in December of 2009 the media was swept up in the story - with lenses and microphones trained on Susan's husband, Josh. He said he had no idea what happened to his young wife, and that he and the boys had been camping in the middle of a snowstorm.

In 1977, in an Ohio Amish community, pregnant wife and mother Ida Stutzman perished during a barn fire. The coroner’s report: natural causes. Ida’s husband, Eli, was never considered a suspect. But when he eventually rejected the faith and took his son, Danny, with him, murder followed. What really happened to Ida? The dubious circumstances of the tragic blaze were willfully ignored and Eli’s shifting narratives disregarded.

In 1911 two British heiresses, Claire and Dora Williamson, read a brochure about a revolutionary fasting treatment that promised a lifetime of good health. The sanatorium in the village of Olalla, west of Seattle, was surrounded by a beautiful forest, sparkling waters and fresh air. The sisters agreed it sounded perfect and exactly the restorative holiday they needed. But within a month of arriving, under the supervision of Doctor Linda Burfield Hazzard, Claire and Dora began to realise the frightening truth – they were not patients but prisoners at the isolated sanitorium.
