Arthur Catherall (1906-1980)

British author born in Bolton in 1906. He was mainly known for his adventure books which were for the most part aimed at boys. He had plenty of personal experience to write about, having served in the R.A.F. and travelled widely on land and sea, often in treacherous conditions, as well as pursuing a number of adventurous hobbies such as mountain climbing and sailing. He was an extremely prolific writer who wrote under a number of psuedonyms. His stories were set all over the globe and although best known for his boy's adventures, also wrote for both sexes and for adults, as well as penning a number of short stories.

Amongst his books were a few animal stories, one of which was horse-related. I think, although I am not 100% sure, that it was the only one.

Collector's info:
This was reprinted a few times in America, but strangely not in the UK. As such, it is actually easier to find in America, although not extremely hard to get hold of here either. It is usually low cost.
