Bigges Hits the Trail by W. E. Johns was first serialized in 10 parts in
The Modern Boy, issues 385 to 394 from 22 Jun 1935 to 24 Aug 1935 under the title
The Mountain of Light.
It was then published in book form by Oxford University Press in August
1935. Since then there have been at least 16 other editions in the
English language.
The book is notable for being the second, and last, "Dickpa" novel and has given rise to a number of interesting derivative works.
