Query: Engaging true treasure hunt story. Amazing.

I read a copy I had borrowed from the library and was so fascinated with the story I had to purchase a copy for my library. This is better than a fiction story because the obstacles and challenges are such that you couldn't have made them up. It is a marvelous personal account of the salvage of the treasure of the SS Central America that sunk in 1857. 400 lives were lost in that. Kinder does a good job of reconstructing the last moments of the ship before it goes down in a terrible storm with 21 tons of gold. The salvage effort takes place below 8000 feet of sea water! Kinder himself is quite a character of interest.
