He returned to New York in 1911, where he began working first for the publishers of the "Catholic Encyclopedia", the "New Standard Dictionary", and then the" Century Dictionary". In February 1912 his poem "The Piper" appeared in "Harper"'s magazine. His first short story, "Battle," sold soon after to "Smart Set" magazine for $50, appearing in the February 1914 issue. He sold more stories; some of these were anthologised in his first book, "Stories Without Women", 1915. He then began working on his first novel, "The Stranger's Banque"t (1919). He was a prolific novelist and short story writer from that point on. His novel "Field of Honor" was published posthumously in 1929. His poems were collected into an anthology and published as Poems (1934).
