Season 2

In the opening installment of a two-part story, DI Martha Bellamy's neighbour, barrister Jonathan Moxton, is found at his home badly injured, his wrists bound with a belt and a pair of knickers stuffed in his mouth. DS Jack Weston surmises he may have been involved in a sex game that went catastrophically wrong, and suspicion falls on Saul Hammond, the man who discovered him.
