About the author
Harlan Page Halsey was an American writer and publisher born in 1837 and died in 1898. He is best known for writing under the pen name Old Sleuth, a name closely tied to some of the most popular detective dime novels of the late 19th century.
His breakthrough came with Old Sleuth, the Detective in 1872, a work often described as an important early detective serial in the United States. Halsey went on to produce a large body of sensational fiction, helping shape the appetite for serialized mystery and crime stories among everyday readers.
Accounts of his life also describe him as a businessman in Brooklyn, and some sources note that he was known in civic life as well as in publishing. Even if many of his books were written for quick popular entertainment, his place in the history of early American detective fiction remains notable.
