Endeavour's return to duty at Castle Gate with a newfound sobriety coincides with a gruesome discovery in a college garden linked to an Oxford orchestra.

Endeavour suspects a connection between a woman's disappearance and her past employer but another missing persons case demands his attention. This time, it's a notable artist, whose work adorns the covers of a series of paperback mysteries.

A series of death notices in the Oxford Mail, each with a cryptic message, provides clues to Endeavour’s final investigation, while Thursday’s past catches up with him.
