Jamaica Inn - Daphne du Maurier

From the author of Rebecca and The Birds: a classic thriller of shipwreck and murder, "rich in suspense and surprise" (New York Times Book Review).
On a bitter November evening, young Mary Yellan journeys across the rainswept moors to Jamaica Inn in honor of her mother's dying request. When she arrives, the warning of the coachman begins to echo in her memory, for her aunt Patience cowers before hulking Uncle Joss Merlyn. Terrified of the inn's brooding power, Mary gradually finds herself ensnared in the dark schemes being enacted behind its crumbling walls — and tempted to love a man she dares not trust.
The inspiration for the 1939 Alfred Hitchcock film.
