A sequence of extraordinary events over the past 300 years. A chain of intrigue, deceit, greed and murder. The loss of H.M.S. Association with all hands in 1707. An admiralty clerk's secret mission thirty years after. 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 recognises but cannot identify. A conspiracy of circumstances that is about to unravel his life. And with it, the past.
