China Seas by Crosbie Garstin Published by Chatto & Windus, second impression October 1930
The adventure novel was the basis for the 1935 MGM film of the same name starring Clark Gable and Jean Harlow.Unfortunately, it is missing the dust jacket, however this ex-library book is in good condition, with some bumping to the cover edges, age colouring of the pages and very slight separation from the spine of some sections.  This novel is getting increasingly scarce to source.
