Arthur Cheney Train (1875-1945) was an American lawyer and writer of legal thrillers, particularly known for his novels of courtroom intrigue and the creation of the fictional lawyer Mr. Ephraim Tutt. Born in Boston, Massachusetts, he was the son of lawyer Charles Russell Train who served for many years as attorney general of Massachussetts. Train graduated with a BA from Harvard in 1896 and LLB from Harvard Law School in 1899. In 1901 he became assistant in the office of the New York County District Attorney and in 1904 embarked on his literary career with the publication of the short story The Maximilian Diamond. He ran his two careers in parallel until 1908 when he left the District Attorney's office to open a general law practice. He continued writing, producing novels, non-fiction works on various aspects of the legal system, numerous short stories, journalism and plays. This work, subtitled Sidelights on the Administration of Criminal Justice, was first published in 1906 and is reprinted from the enlarged edition of 1915.
