This is a Fiction Crime Stroy Book. The book says that Those who desire to peruse works that tell about Heaven only, are urged to drop this book and run. I was an inmate of the Kansas penitentiary for sixteen months, and make mention of what came under my own observation in connection with what I experienced. While an inmate of this prison I occupied cells at various times with convicts who had served terms in the Missouri prison. From these persons I gathered much useful material for my book. After my release I visited the Missouri penitentiary, and verified the statements of those criminals, and gathered additional material from the prison records and the officials. I have written chiefly for the youth of the country, but all ages will be deeply interested in the following pages. A large majority of the convicts are young men from sixteen to twenty-five years of age. They had no idea of the terrible sufferings of a convict life, or they surely would have resisted temptation and kept out of crime.
