Librarian Note: There is more than one author in the Goodreads database with this name.

JAMES R. CALLAN took a degree in English, intent on writing. When writing didn’t support a family, he went to graduate school in mathematics, then pursued a career in mathematics and computer science. He has received grants from the National Science Foundation, NASA, and the Data Processing Management Association. He has been listed in Who’s Who in Computer Science, and Two Thousand Notable Americans.

But writing was his first love. He has published a number of books and picked up some awards along the way. Cleansed by Fire, the first of the Father Frank mystery series, and Murder a Cappella, another mystery which Callan wrote with one of his daughters, Diane Bailey, were both published in 2012.

Callan lives with his wife in east Texas and Puerto Vallarta. They have four grown children and six grandchildren.
