In January 1901, Train became assistant in the office of the
New York County District Attorney. In 1904 he started his literary career with the publication of the
short story "The Maximilian Diamond" in ''
Leslie's Monthly''. He ran the two careers in parallel until 1908 when he left the District Attorney's office to open a general law practice in the Mutual Life Building at 34 Nassau Street in New York City. Several other works by Train were filmed, including
Illusion (1929), ''
His Children's Children (1923), and The Blind Goddess'' (1926). In 1912, Train, who as a former assistant to New York County District Attorney
William Travers Jerome had dealt with Italian criminals who emigrated to the United States and the
Black Hand, attended the
Cuocolo Trial in Italy against the
Camorra, studying that
Mafia-type organisation and the functioning of Italian justice. From 1915 to 1922, Train was in private practice as a lawyer with
Charles Albert Perkins while continuing to write, not just novels but short stories, plays, and
journalism. In 1919, he created the popular character of Mr. Ephraim Tutt, a wily old lawyer who supported the common man and always had a trick up his sleeve to right the law's injustices. After 1922, he devoted himself to writing. ==Personal life==
