author
b. 1867
A Boston-born writer, poet, and dramatist whose work moved between mystery, verse, and Catholic history. Best known today for The Incendiary, he left behind a small but varied body of late 19th- and early 20th-century writing.

by William Augustine Leahy
Born in Boston on July 18, 1867, William Augustine Leahy was an American author whose surviving bibliography shows an unusually wide range. His work includes the mystery novel The Incendiary: A Story of Mystery, the drama The Wedding Feast, the poetic drama The Siege of Syracuse, and a historical volume on Catholic churches in Boston and nearby St. John's Seminary.
That mix of fiction, drama, poetry, and local religious history suggests a writer comfortable moving between imaginative storytelling and documentary or cultural subjects. Modern readers are most likely to encounter him through The Incendiary, which has remained visible through library catalogs, Internet Archive, and Project Gutenberg.
Reliable biographical information about Leahy is limited, and no detailed modern reference profile appears to be readily available beyond basic catalog and author records. He died on June 4, 1941.
