In 2017 Irish journalist Senan Molony caused a worldwide media flurry with his Channel 4 documentary Titanic: The New Evidence. The documentary, on which this book is based, revealed that there was an uncontrolled coal bunker fire on the Titanic. For Molony, who had spent decades studying the Titanic, the ‘smoking gun’ came with the discovery of a trove of photographs documenting the ship’s construction and preparations for its maiden voyage. The photos had been taken by the engineering chief of Harland and Wolff, the Belfast-based company that built the doomed vessel. Molony and a collaborator purchased the photographs from a descendant of the company’s director, who had found them stored in an attic. As they pored over the images, Molony was shocked to see a 30-foot-long black streak documented on the outside of the Titanic’s hull, close to where the iceberg struck its starboard side. Experts agreed that such a fire would have significantly hastened the sinking. The Titanic might otherwise have lasted until daylight, with many more being saved by a flotilla of arriving ships. In Titanic: why she collided, why she sank, why she should never have sailed, the Molony looks in detail at the tragedy and outlines numerous theories about what led to the Titanic's sinking.
