This is a wonderful story. I felt caught up in the 1960s and the realistic portrayal of the social, political and business climates of the day. The side story of the unrest during the Congo's fight for independence had me interested enough to do some extra reading on what happened there.
Unlike some of the other reviewers I never had a problem with the timeline jumps and was invested in all the characters. The plot line that takes place forty years later is completely necessary to bring the original story to it's conclusion.
**Spoiler Alert** The only thing that wasn't clear to me was how Laurence Stirling knew about the P.O. box and was able to get his secretary to remove letters from it. Even after reading the book twice I still never picked that up. Any suggestions?
