The Listerdale Mystery

A bankrupt upper-class family rents a wonderful mansion for a ridiculously low price. The house belongs to Lord Listerdale, who has supposedly gone on a trip but no one knows where. Rupert, the son of Mrs. San Vicente, the tenant, believes that the man is dead and that his body is hidden somewhere in the house. A series of coincidences will help the young man discover the mystery behind the former owner.
