After an illustrious career at London's Metropolitan Police Department, Chief Inspector Cam Fergus accepts a transfer to the Herefordshire town of Ross-on-Wye to wind down his career. The idyllic, sleepy market town is the perfect place to escape the frequent crimes and gruesome murders that Cam dealt with daily at the Met—until the Lady of the Wye surfaces...

Everything points to suicide, but Cam's instincts tell him that things don't add up. And when evidence indicating foul play is found at Wilton Castle, the case quickly develops into a murder investigation. As victims begin to pile up, Cam races to find the identity of the killer before more innocent lives are lost.
