Tom Barnaby joins the Causton Chamber of Commerce trip to Brighton as he is suspicious of dodgy mayor Hicks' plan to buy coastal land on which to buy chalets. Also opposed to the plan is Lady Matilda William,who has had threatening letters, as have the local vicar, oily property developer Hugh Dalgleish and hotelier Jenny Russell. Lady Matilda is descended from Richard of Guillaume,a ruthless contemporary of William the Conqueror,and believes that her son Richard,last of the line and brain-damaged for twenty years,was the victim of ancestral jealousy.In Brighton Dalgleish is murdered with the sword stolen from Guillaume's tomb and Hicks is arrested for fraud. Having learnt how Richard came by his accident Barnaby is convinced that Richard and not the property scam is the cause of yet another victim being claimed by the sword of Guillaume.

　　《妓女谋杀案》集合了部分优秀的英国女演员，包括了Sarah Lancashire、Juliet Aubrey以及Kate Dickie。编剧Stephen Butchard通过与当地警方、戒毒机构以及受害者家属的交流，拼凑起这些女孩的故事。她们的死亡并不是因为她们是妓女而是因为她们有毒瘾，卖淫只是为了有钱购买毒品。这些都是人生遭遇残忍转折的普通人。她们不是完人，但她们的命运本不该如此。
