William Jeremiah Coughlin (1929 - 1992) is the popular author behind such novels as *The Twelve Apostles, Her Father's Daughter, Her Honor, In The Presence Of Enemies,* and *Shadow of a Doubt* (1991). He also wrote *Cain's Chinese Adventure* and *The Mark of Cain* under the pseudonym Sean A. Key.[1] Coughlin combined a career as a United States administrative judge in Detroit with that of a best selling novelist. It is often thought that his experience as a judge may have been some inspiration for his law- and courtroom-themed thrillers.
