Janet is promoted to sergeant but steps down to give it to Rachel as she feels she is needed more at home. The pair join the search for eighteen year old Robin McKendrick， a simple lad reported missing by his boss， landlord John Rivington. Pub regulars are unforthcoming until a boy called John tells Janet that an ex-soldier known as Jackie-Boy locked Robin in his car boot as a cruel prank. He later reported the car as stolen. Another witness claims that Jackie- Boy dumped his car in a quarry with Robin still in the boot. In the process of the investigation Gill identifies another body found in the river， that of Mandy Sweeting， who disappeared two decades ago.
