The House That Dripped Blood
A Scotland Yard investigator looks into four mysterious cases involving an unoccupied house.
Tim Hanley, an American agent, posing as a lawyer with the United States Embassy in London, and Reggie Oliver, a Scotland Yard detective, posing as a music critic are both keeping their eye on Carla Nillson, a famous singer, whom they suspect of espionage. They all meet in London, then in Lisbon, and eventually in New York City, where Carla sings on the radio.
A newlywed fears she's going mad when strange things start happening at the family mansion.
