The story that follows this introduction is literally true. There died lately, in a Western State prison, a man of the class known as habitual criminals. He was, at the time of his death, serving out a sentence for burglary. For thirty years he had been under the weight of prison discipline, save for short periods of freedom between the end of one term and the beginning of another.
Because of this man's exceptional qualities, as contrasted with those of the multitude of criminals, he was induced, semi-officially, in a friendly way, to write the story of his life. He accepted the proposition made to him, though, consistent with his quality, not quite fulfilling his pledge, omitting, as he did, certain hard details of the later part of his criminal career. This was but natural, and, perhaps, [vi]it is the one incident which shows that the man realized, in some measure, the truth as to his own character.
