The House on the Cliff

On a stormy night, brothers Frank and Joe Hardy hear a scream coming from an old, supposedly haunted house perched on the cliffs above Barmet Bay. When they learn the house is tied to a smuggling ring their father is investigating, the boys dive into danger, especially after their father disappears. Racing against time, they explore secret caves beneath the house, confront smugglers, and work to solve the mystery and save their father.
