In the summer of 1862, a group of young artists led by the passionate and talented Edward Radcliffe descends upon Birchwood Manor on the banks of the Upper Thames. Their plan: to spend a secluded summer month in a haze of inspiration and creativity. But 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 one hundred and fifty years later, Elodie Winslow, a young archivist in London, uncovers a leather satchel containing two seemingly unrelated items: 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?
