A sequence of extraordinary events over the past 300 years provides the links in a chain of intrigue, deceit, greed and murder: The loss of "HMS Association" with all hands in 1707. An admiralty clerk's secret mission thirty years afterwards. A fatal accident during a dive to the wreck in 1996. An expatriate's reluctant return home ten years later. The simple task he has come to accomplish, shown to be anything but. A woman he recognizes but cannot identify. It's a conspiracy of circumstances that is about to unravel his life. And with it, the past.
