A true story of one agent and his investigative experience as a United States Secret Service special agent assigned to the New York Field Office which was at one time located at 7 WTC. Dual Mission is a true story that at times reads as a novel. It is the account of one ordinary person who vanishes into the "uncharted waters" of long term investigations at an agency where such work is an unknown. His personal mission to take down the New York Mafia, the rogue pitcher, Denny McLain and other global investigations become his mission. A mission with a dual purpose.
