Harrigan and Hoeffler are agents for the THREE.
In 1953, a meeting in Washington between three high-level government figures and three extremely powerful men of finance. They met to discuss a growing problem with security in the nation, namely that as good a job as the various Intelligence agencies were doing, they were hampered by the fact that they were known. Created then was a small anonymous agency, funded through the financiers, known as the THREE, so government auditors never got wind of it. The agency would be comprised of a small cadre of highly trained, and highly paid, operatives who worked in secret. They would go in quietly, do their job, and get out unseen. Loose ends could be tied up by the known Agencies who would get the credit
Thousands of potential agents were considered. Potentials had to be unknown to the community. They had to be able to think independantly and quickly. Misfits was the term the head of the organization, known as the Old Man, considered. The list was culled to hundreds, and then down to less than a score. Finally, two men were chosen, Harrigan and Hoeffler.
These two men had known each other since grade school. Now 33 years old, they had tried, succeeded, and then grew bored with a variety of careers. Both excellent sportsmen, they had served in the military for a time and then numerous businesses. An art gallery, an electronics firm, selling used cars, running a ski lift, ranching in Arizona, and so on. Get in on something new, work a year at it, and then move to something else.
After agreeing to work for the Organization, they were trained in every field they might possibly have to work with: guns, knives, gadgets, explosives, codes. In all matters they excelled. And were bored. Action was their goal and they got it.
Throughout all their escapades, though, I never found out their first names. Perhaps they never had them. That would be just like them!
