England, 1957. Olive Kersey's only love never returned from World War II, and now, she's alone and penniless. Then, the last person she ever expected to see again returns to Southwold. Olive's childhood friend, Margery Paxton, arrives to claim her inheritance: Mersea House, a stately old home she plans to turn into the town's only lodging. Olive's life takes a sunny turn when Margery hires her to run the establishment. But Mersea House holds its own mysteries - and its own dangers - and looming secrets may destroy the friendship they've created.
