Here's a recommendation for you:
Lion In The Morning by Henry Seaton.
Although not a hunting book it does have some mention of hunting in it. The book is about the life, times, travels & troubles of a young British graduate who signed up in about 1910 as a civil servant in British East Africa (later Kenya) and goes a long way to help us understand why & how things were for the early settlers.
The book is written with typical British understatement & gentle humour.
We don't have it on our site yet but will try to get it on there but wherever you buy it from, I HIGHLY recommend it.
