A young couple who have just eloped get into a car accident and a heap of trouble when they stumble into a tramp and the Green Dragon Inn. They have to solve the mysteries of why the Inn was abandoned, who locked the cook in the cupboard, and why the Chinaman is after the blind man's dog. Originally published as 'The Green Dragon' in 1926, the book was republished as 'At The Green Dragon' in 1929.
