On that fatal April night in 1912, the world's largest moving object disappeared beneath the waters of the North Atlantic in less than three hours. Why was the ship sailing through waters well known to be a "mass of floating ice"? Why were there too few lifeboats, so that 1,522 people were left to perish at sea? Why were a third of the survivors members of the crew? Based on the sensational evidence of the U.S. Senate hearings, eyewitness accounts of survivors, and the results of the 1985 Woods Hole expedition that located and photographed the ship, this electrifying account vividly recreates the doomed vessel's last desperate hours afloat and fully addresses the questions that have continued to haunt the tragedy of the "Titanic."
