Capstick's " Death in the Long Grass" was my 1st "Africa" book and was my favorite for a long time. I think I was about 15 or 16 when I first read it. I have longed to hunt in Africa ever since.
A wife (of over 28 years!) and family has prevented me from making it there yet. But I'm not complaining, My wife understands that some day she will lose me for a couple of weeks to fulfill my dream. I just cannot talk her into going with me (Australia is much more interesting to her though and the company I work for has a couple of facilities there!).
Once I read "The Last Ivory Hunter" it became my current favorite.
Looks like from the list above I'm in good company with my choices (of course I am, its Nitro Express) and there seems to be others that I need to read soon.
