A new detective series for fans of the bestseller 'The Thursday Murder Club.' Three ladies in pursuit of a real serial killer.

Meet Judith Potts, a seventy-seven-year-old woman who lives happily alone in a historic house. There is no one in her life who would tell her what to do or how much whiskey to drink. In her free time, she creates crosswords for newspapers and swims naked in the Thames.

One evening, during one of her regular swims, Judith witnesses a brutal murder. The local police do not believe her story, so she takes on the investigation herself. She is assisted by Susie, a local dog lover, and Bex, the vicar's wife. Together they found the Marlowe Murder Club. What an occupation for English ladies! But then, when another body appears, our heroines begin to realize that a real serial killer has appeared in the town.
