Fiction. MISSING MATISSE is a novel with a puzzle, set in the contemporary world of art theft and the historical reality of World War II, France. The heart of the story is the enigmatic and complex Lydia Delectorskaya, a Russian orphan who became Matisse's muse, model, caregiver, administrator, and companion for twenty years. Lydia Delectorskaya is a fascinating figure, though little is known about her life after Matisse's death. Jan Rehner gives Lydia a voice, and pays tribute to her remarkable contribution to some of Matisse's greatest paintings.
