This is the Titanic book you are looking for. Far from being one of the many novelizations or non-fiction novel type history reports, this is testimony straight from the survivor's mouths about what happened the night disaster struck. We are all familiar with C-Span senate hearings of the past few decades, but this is one of the interesting ones condensed into an exciting and informative volume. Questioning began mere days after the accident as the Carpathia pulled into New York with the few souls who made it. Even the slightly repetative nature of the senator's questions from person to person revealed a new fact or two about the sinking of the unsinkable ship.
For those whose knowledge of the Titanic comes mostly from James Cameron, this volume is a wealth of first hand information that didn't get covered in the blockbuster film. Most shocking was that the ship, the Californian, was within sight of the Titanic and saw her distress rockets but didn't come to her aid, even though they could have gotten there before the ship sank. This volume also covers other interesting aspects of the case like the yellow journalism practiced as papers vied for exclusive rights to stories, Bruce Ismay trying to get everyone on a ship back to England before they could be questioned in America and The Wall Street Journal giving false reports that Titanic was fine so that certain stocks didn't plummet. Many of the controversial aspects of the case are addressed to a satisfactory degree, but you can see some pat answers and bet hedging in some of the testimony.
