TITANIC'S LAST SECRETS : THE FURTHER ADVENTURES OF SHADOW DIVERS JOHN CHATTERTON AND RICHIE KOHLER
by Brad Matsen

In August of 2005 shipwreck divers John Chatterton and Richie Kohler discovered new evidence on what had sunk the Titanic. Working with a forensic marine analyst they were able to uncover archival information that had never been seen by any historian.
Brad Matsen writes a meticulously, spell-binding story of the great ship's construction and of its demise. There were compromises made that would, in the end, doom most of the passengers and the crew.
The conclusion is a real shocker.
Matsen did his own research, which can be found at the end of the book, by the Notes and the extensive Bibliography he used.
Titanic's Last Secrets is a terrific read.
Highly recommended.
