 The lease on the Dupayne Museum is almost up and under the terms of their father s will, all three of the Dupayne children must agree to continue or the museum is to close. Neville Dupayne is dead set against continuing the museum when the money could be used for a much better purpose. One of the museum s key attractions is the Murder Room, displaying information on a series of notorious murders from between the two World Wars. When Neville dies in a way reminiscent of one of the murders on display in the Murder Room, Commander Adam Dalgleish is asked to investigate. There are any number of suspects: his siblings, several museum employees who will lose their job, his secretary with whom he once had an affair and his daughter who felt he was an absentee father. A second murder reveals some of the activities of the upper classes and the solution lies in a long-ago wrong that someone is seeking to right.
