I picked this book up mainly on the basis that "Hell's Gorge" is an interesting title. I must admit I then reacted cynically on finding out that John Le Carre gave it the thumbs-up; I hadn't got the man down as either an historian (as he studied languages at university) or an expert on the Panama canal, so the fact that he was approving it made me slightly dubious - a little bit like me heartily endorsing something I know nothing about ("Mr Weston says our infra-red goggles are 'the best on the market'" isn't really going to persuade anyone.) In the end I was swayed by the allure of the glossy old photographs that feature, and the fact I felt I needed a third book for my trip.
And thank goodness I did. This is an exceptionally interesting work that doesn't alienate the reader, despite the complexity of how a canal actually operates (I foolishly thought it was just basically a trench filled with water, which it's not.) Parker explains things in great detail but at sufficient pace; my lack of any engineering knowledge meant only that I identified more with Lesseps than the other, rival theories of canal construction (Lesseps basically saying that to build the canal you dig a trench and fill it with water.)
The book takes the reader through both serious efforts to build the canal, one by Lesseps and the French in the 1880s and the other, successful, American effort a decade or so later. Whilst reading I suddenly realised why Le Carre was been quoted as an approved reader - this story has intregue, plotting, secrecy, double-dealing, human catastrophe - and quite a bit of pig-headedness. Stuff, essentially, from a Le Carre book. Except this was real, which makes it better.
Not only that but the characters are so vividly portrayed that I now need to go and read biographies of Lesseps and Teddy Roosevelt, as my curiousity has been aroused by this tome.
So buy and read this book. I'm not John Le Carre, but I'm with him all the way on this. Just don't trust me on infra-red goggles.
