A mixture of conspiracy theory, personal testimony and history, this is a useful start for those who want to know what happened on that fateful night in April 1912 when the Titanic foundered. But as the authors admit at the outset, it is something of an unusual offering. Writer Dan van der Vat admits that he disagrees with the conspiracy theory espoused by co-author Gardiner but that doesn't harm the book in any way. We learn about the building of the great ship, the key personnel, the sinking, controversial rescue and the inquiries. The authors go into considerable detail but the book is always readable and written, despite the subject matter, with some humour. Whether you agree with Gardiner's theories - and I'm not going to give them away here - or not, this is a valuable addition to an already crowded genre.
