When a homeless man is shot in the deserted mansion of one of Bath's most prominent industrialists, the inventor Max Crockett, newly arrived Londoner DCI McDonald and long-serving DS Dodds rally together to try and discover the killer.

In the Crockett family, they find an outwardly perfect, close-knit group with three successful daughters in loving relationships, devoid of any obvious motive to murder, but it soon becomes apparent that each have their own secrets to hide.

Faced with evasive suspects and a seemingly inexplicable crime, they quickly learn that not all is as it seems in the House of Crockett.
