Nothing, except perhaps the landing of flying saucer in one’s backyard, is quite so disruptive of everyday life as the discovery of sunken treasure. There are very few people in the world who can confirm this, but by a series of most unlikely events I happen to be among them. This book is the story of that experience, which I would not have missed for anything – but under no circumstances would wish to repeat; for it cost me my health and very nearly my life.
