Gracie, as others have said, died after the disaster due to his time in the sea, but in the time he had left he managed to collate the accounts of a large number of survivors. After describing his memories of the time immediately after the collision, he orders the accounts of other survivors boat by boat, in an orderly and clear fashion. My only criticism is that he includes a lot of repetition, but that is bound to occur with so many people recalling past events. Before reading this I did not know much about the disaster, and Gracie's work proved to be an excellent introduction to the topic. This is certainly my favourite account of the Titanic's sinking.
