When Peter, Margaret and Celia inherit a rambling old house from an uncle, they consider it to have a certain charm despite its ramshackle appearance. But suspicion is roused when they discover that for years no one has been very keen to set foot in the place - indeed, their uncle chose to live quite far away from this particular property - the reason being that it is said to be haunted. The things that go bump in the night take on a more sinister air when a murder is committed.
