I got this one:

Not really in a position to recommend it on the grounds that I ain't actually read it yet (I am rather backed up in that department), but his book "Fuzzy Wuzzy", on the two campaigns on Sudan's Red Sea coast is excellent, so I know he writes good stuff.
Edit: Scooped by Carlos.
One thing, I think it may be out of print, rather expensive on Amazon at the minute, and that's for second-hand copies...
