“Saya loves the wild grey Arabian stallion so much that he’d rather own him than any of his father Sheik Akim Abou’s other horses, but the grey has been a menace to the tribes and is to be shot.”
Hobart Donavan (1905 - 1976) was a scriptwriter, who wrote for, amongst others, the Loretta Young Show. He wrote the scripts for several films, including Escape to Burma. He was married to June Foray, who was well known for providing the voice for Rocky the Flying Squirrel on the television series The Bullwinkle Show. Hobart Donavan wrote one horse book (as far as I am aware, this was the only book he wrote).
Finding the book:the book is easy to find, and not expensive. It wasn’t published in the UK.
