VG - VG+. 1936 Popular Library #32, first printing. Softcover. The basis for my favorite Alfred Hitchcock movie - ‘The Lady Vanishes’. White was often mentioned alongside her contemporaries Agatha Christie and Dorothy Sayers during her run of mystery novels in the 1930’s & 40’s. This was just the first book that was optioned for a film; her books also provided the basis for the films ‘The Spiral Staircase’ and ‘The Unseen’.
