Broken

When the body of a young woman is discovered deep beneath the icy waters of Lake Grant, a note left under a rock by the shore points to suicide. But within minutes, it becomes clear that this is no suicide. It's a brutal, cold-blooded murder.

All too soon, former Grant County medical examiner Sara Linton, home for Thanksgiving after a long absence, finds herself unwittingly drawn into the case. The chief suspect is desperate to see her, but when she arrives at the local police station, she is met with a horrifying sight—he lies dead in his cell, the words 'Not me' scrawled across the walls.

Something about his confession doesn't add up, and deeply suspicious of Lena Adams, the detective in charge, Sara immediately calls in the Georgia Bureau of Investigation. Shortly afterwards, Special Agent Will Trent is brought in.
