Arriving on the windswept Ile de R' off the coast of France, Tabby Dewhurst is heartbroken and penniless, unable even to afford a room for the night. Then she overhears a villager repeating aloud the access code to her front door and, hardly believing her own actions, Tabby waits for the villager to leave and lets herself into the house . . . And so she enters the strange, hidden world of Emmie, whose sudden offer of friendship is at odds with her obsession with her own privacy. Soon Tabby begins to form suspicions about Emmie, suspicions that will lead her back to England - and to a scandal with shattering consequences.
