A baffling case greets Vera as the detective returns for a seventh series. DCI Vera Stanhope is called to a remote island when the body of a local wildlife ranger is washed up on its shore.

Vera and her team quickly establish that the ranger, Gemma, was murdered – and wonder how the killer could have escaped the island by boat unnoticed.

‘We’re looking for Batman, are we?’ scoffs Vera when one of her troops comes up with a particularly wild theory.

While it seems Gemma was well liked, Vera soon finds plenty of people who might hold a grudge against her. Brenda Blethyn is first class as our mac-wearing hero, while the mystery keeps you guessing until the final scene.
