Two rival gangs of bodysnatchers are waging an all-out war for turf and bodies in the East End, so Wisbech sends Strauss and Mabel in to work undercover. Meanwhile, Rabbit finds himself ostracised from the case due to his age - these are youth gangs - and he takes umbrage when he is sent off to an old people's home to investigate a spate of mysterious poisonings instead. But is he really too old for this game? And if so, what's to become of him? Comedy, starring Matt Berry, Alun Armstrong and Freddie Fox
