The genteel tranquility of a country house party is shattered when the gamekeeper is shot. Was his death the result of his recent indiscretions, or long-buried secrets?

The weekend was supposed to be an enjoyable time with her family at the neo-Gothic manor of Lord and Lady Kershaw, but when the gamekeeper is murdered, Cleo can't rest until the killer is caught. As a witness herself, she's frustrated with the incompetence of the local police who lay the blame on a man who conveniently disappeared. When she realizes their ineptitude is a result of Lord Kershaw's influence, she focuses her investigation on the earl and his family, against the wishes of her uncle.

The arrival of her suspects at the Mayfair Hotel allows Cleo to continue the investigation after the country house party ends, but what she discovers unnerves her. The gamekeeper's reputation for seducing young women has left a trail of broken hearts, from the lowest maid to the highest lady. But could there be another reason for his murder?

Meanwhile, the hotel staff have secrets of their own to hide. As loyalties are tested on several fronts, Cleo needs her friends more than ever if she is to unravel the mysteries, both old and new.
