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. Set as the war-shattered Edwardian summer surrenders to the decadent twenties, The Shifting Fog is a thrilling mystery and a compelling love story.
