Plot

Two boys find the body of a woman, involved in a child abduction case. Harrow and Dass vie to find out about the River Bones clue. Harrow gets there first. After her boyfriend is mugged Fern makes an agreement with a drug dealer.

When a female skeleton is discovered in the backyard of Terry Connelly, a Vietnam veteran with PTSD, he becomes the prime suspect in what appears to be an open-and-shut case. But when the victim is identified as Sally Chenery, a homeless woman, Harrow decides to dig deeper. He returns to the scene of the crime and discovers several more bones from Sally's skeleton, and a camera, lodged in a tree. Meanwhile, Simon has extracted a Radius Compression Plate from the river bones. Dass hopes to identify their John Doe via the serial number on the plate. Fortunately for Harrow, the Sally Chenery case takes precedence. The photos from the camera in the tree are found to be almost entirely of Noah Dalton, a boy who lived in the neighbouring property to Connelly some years ago. His adoptive mother, Cassandra Dalton, reveals that Sally was a relentless stalker. She claimed that Noah was her son. They feared for their safety and moved house several times - but she always managed to find them again. Delving deeper into Sally's obsession with Noah Dalton, Harrow discovers a tragic twist. With the truth finally revealed, Dass returns to her investigation of the river bones, attempting to identify the John Doe through the serial number of his orthotic plate. But Harrow runs his own off-book investigation, determined to keep Dass from learning the John Doe's identity.
