In the summer of 1862, a group of young artists descends upon Birchwood Manor in rural Oxfordshire. By the time their stay is over, one woman has been shot dead while another has disappeared; a priceless heirloom is missing; and Edward Radcliffe's life is in ruins. Over 150 years later, Elodie Winslow, a young archivist in London, uncovers a leather satchel with two seemingly unrelated items in it: a sepia photograph of an arresting-looking woman in Victorian clothing, and an artist's sketchbook containing the drawing of a twin-gabled house on the bend of a river. Why does Birchwood Manor feel so familiar to Elodie? And who is the beautiful woman in the photograph? Will she ever give up her secrets?
