It is 1922, and in a hushed south London villa life is about to be transformed, as genteel widow Mrs Wray and her discontented daughter Frances are obliged to take in lodgers. Lilian and Leonard Barber, a modern young couple of the 'clerk class', bring with them gramophone music, colour, fun - and dangerous desires. The most ordinary of lives, it seems, can explode into passion and drama...A love story that is also a crime story, this is vintage Sarah Waters.
