Summer 1924: On the eve of a glittering Society party, by the lake of a grand English country house, a young poet takes his life. The only witnesses, sisters Hannah and Emmeline Hartford, will never speak to each other again.

Winter 1999: Grace Bradley, 98, one-time house-maid of Riverton Manor, is visited by a young director making a film about the poet's suicide. Ghosts awaken and memories, long consigned to the dark reaches of Grace's mind, begin to sneak back through the cracks. A shocking secret threatens to emerge; something history has forgotten but Grace never could.

A rich and engrossing story of love, passion, secrets, and lies set in the gaiety, glamour, and grand country houses of post-war Edwardian England.
