Harmony is not on the calling card for this group of friends when their holiday camp is disturbed by murder and revenge…

June 1998: Elodie Marshall has committed a terrible crime. But when she’s deemed unfit to plead, she is sentenced to living within the confines of a mental health facility.

Present day: Sleuthing librarian Pru Pearce and her friends from the Winterbottom Women’s Institute are about to embark on their annual getaway. The 1960s Butlins style Harmony Hollows Resort has caught their attention for a few reasons: the northern ballroom championships and the unsolved double murder from 1983.

But what the women thought was just a cold case mystery soon steps into the present when a murderer, dubbed The Grim Sleeper, strikes. Soon, Pru and the other WI women are dragged deeper into the mystery investigating both the 1983 and present-day murders. But this is no evening entertainment, this is real life, and everyone is in danger…

Can Pru uncover the truth before another innocent camper is struck off? And are her friends in chalet 13 destined to meet a grisly end in this killer comedy by the author of The Constable Mavis Upton series.
