Luther Gage is an agent with the Escape Committee.
That rather unusually sounding name for the "organization" comes from the fact that it is an ad-hoc created by the whim of the current sitting President of the United States, James Ballard.
Some time before the events of the first recorded adventure of Gage, the Chief Executive had decided that his regularly held meetings with a small group of people, Vice President Jameson, high ranking Senator Atwood, General Spaulding, and National Security Advisor Jurgens should take a deeper purpose than just routine briefings. Though the existence of this Escape Committee, so named by the President, was a secret, he made sure that transcripts of the meetings were made.
The Committee's purpose was to "review situations in which Americans or others were being wrongfully held or imprisoned in foreign places by governments, individuals, or groups and in which human rights were abridged or national security was impaired". The President had empowered the committee to take "extraordinary action" to rectify the situation. Once a motion was approved by the Committee, one of several agents specifically assigned to the Committee would be given the mission. "Nobody outside the [members], the secretary [taking the notes], and the employed agents even knew that the committee existed. Not the CIA, not the FBI, not the NSA."
General Spaulding was the face of the committee as far as the operatives were concerned. How many agents there were is not revealed but the tone used would indicated that there were not many.
Luther Gage was one of those agents.
Since the Committee had not been in existence for long because the founding President was still relatively new to the job, Gage's connection was still new to it. He had already performed a couple of dangerous missions and had pulled them off sufficiently well enough to be already looked on with favor by the members.
Gage is 6' tall and in quite good shape, his body mostly bone and gristle. "Ex-Green Beret, ex-martial arts instructor, ex-military intelligence officer" Gage had served with honor in Vietnam but had eventually left the military because of changes in it that he disliked. He still served as a Major in the Reserves, though. It was Spaulding who, when directed to find people to be the agents with the Committee had looked up Gage and found him more than anxious to leave his civilian life behind.
