Monica Dean has inherited a large home and has turned it into a sort of exclusive hotel for paying guests. The only problem is that the house seems to be haunted as on at least two occasions, guests have had their windows opened, the furniture smashed and their clothes torn to shreds. Tommy and Tuppence travel to the home and learn that there a valuable secret buried on the grounds. So valuable in fact that someone will stop at nothing to scare Miss Dean into selling.
