Island of the Mad

In 1925, Mary Russell and Sherlock Holmes are pulled from their quiet Sussex life to find a missing woman who vanished from a supervised outing at Bedlam. Their search for the eccentric Lady Vivian Beaconsfield takes them from the grim halls of an asylum to the sun-drenched canals of Venice. Amidst the rise of Mussolini's Blackshirts and the jazz-age glamour of the Lido, the duo must determine if the lady is a victim or a thief.
