Ghosts deals with important art objects which have been misplaced, damaged, stolen or have otherwise disappeared from public view. In the 1980s and 90s, the Isabella Stewart Gardner museum in Boston and the Earl of Bath’s residence in England both lost some of their most prestigious works to thefts and accidents. In this volume, which combines her series on both museums, Sophie Calle embarks on a quest to resurrect the memory of these pieces. She explores their personal meaning to those museum employees and others who knew the works intimately, in a series of profiles on each individual.
