An extra body is found in a coffin just before it’s about to be buried. It turns out to be the body of a local rag and bone man - but why would someone kill him, and go to such elaborate measures to get rid of the body? Soon, Doctor Blake realises that he’s been asking the wrong questions - there’s more than one body waiting to be discovered. A missing man may even still be alive, but can Blake solve the puzzle in time to save him? But finding the answer involves grappling with his own mortality, and Jean worries as his behaviour becomes more and more out of control.
