A storm hits Peridale with disastrous effects. Barker's cottage is destroyed, forcing him to move in with Julia, but she has more to worry about than him leaving his socks around and not putting the toilet seat up. Julia is shocked when the storm also uncovers a secret basement underneath her cafe and even more shocked when she finds the body of a teenage girl who has been missing for twenty years.
The cold case team rushes in, pushing Julia out of her cafe and leaving her to unravel the truth of the past one thread at a time. When she realises the girl, Astrid, was the daughter of Evelyn, the eccentric B&B owner, Julia vows to piece together the events that led to Astrid being trapped in a basement for decades. How did the girl die, and more importantly who killed her? Julia hunts for clues to a case the village had almost forgotten about so she can bring Evelyn the peace she deserves, but will she be able to do it in time before somebody she loves suffers a similar fate?
