The book tells the history of "HMS Dasher" which blew up and sank in about 6 minutes, halfway between Adrossan and Arran, with the loss of about 1200 lives, during the Second World War.
The first part of the book is written as a narrative that describes the sinking of "HMS Dasher"; tells her earlier history, starting with her conversion from an American banana boat and her chequered history as an aircraft carrier; it also considers the reasons for her loss.
The second part of the book reporoduces the stories of various indivdiuals who were on "Dasher" and from which the narrative of the sinking is drawn.
The book also contains factual information on "Dasher", reproduces the notes from the board of enquiry and details of some of those who were lost.
The structure of the book is somewhat lumpy and at times repetitive but it is nonetheless interesting. By its end you feel that you know what happened and also have a sense of the human cost invloved in her loss.
