The River of Diamonds

This is a South African type thriller, set along the southwest coast of Africa in the 60's or so, in the desert called the Namib. It is a story partly about early diamond explorers, and a underground river that supposedly brought millions of diamonds from inland to the Nabian coastal beaches and off shore areas. The thriller aspect is about a fictional underground lake that contains most of the diamonds but is protected by some sort of natural and fatal protection. All people who have attempted to find out extract diamonds from the sea, by offshore ship vacumming, submarines and other methods are killed in horrible and fatally unexplained accidents. One old prospector and a young surveyor and his girl friend are caught in the mystery and its solution. This novel is based upon the unproven sea diamond theory and it is not unitl the late 1990's that vacuuming diammonds from the ocean bottom near the Namib coast proved to be true and profitable. Geoffry Jenkins has written a hard bitten novel, a mixture of great sea adventure and extreme desert survivor tale mixed with the history of diamonds and Africa. It is a good story. I understand a movie was made in 1990 but was a third rate B movie. It would be worth releasing this book and the story is a tale of high adventure. This is one of several adventure tales by Jenkins and I think that it was his best.
