Watch Titanic: The New Evidence live on the web
Investigative journalist and Titanic expert Senan Molony examines recently recovered photographs of the doomed ship, which provide fresh insight into the reasons for its sinking.
The images reveal a strange mark on the hull, which may prove previously overlooked stories of a fire raging in the boiler room.
This blaze may explain why the captain chose to ignore warnings of icebergs ahead and why the vessel sank so quickly after the fatal collision.
