Recently widowed Agnes Lockwood is spending a few days on Tyneside in Northeast England, keen on catching up with her past. But after only a few days at the hotel, an expensive item of jewelry is stolen.
After more jewelry goes missing, Chief Inspector Alan Johnson is assigned to the case. During the investigation, Alan recognizes Agnes as a friend from schooldays and they rekindle their friendship – with Agnes bombarding him with questions about the case.
After having dinner together one evening, they find a body lying on the roadside. Fearing for her safety, Alan warns Agnes to stay away from the case: theft is one thing, but murder is something else.
But being an inquisitive woman, Agnes can’t resist getting involved... too involved.
