The Disavowed are former agents with the CIA.
This is the series name under which the recorded adventures were published. The team of three agents were actually known throughout the Agency during their fair number of years working there as the Razor's Edge. This was likely because these were the men dispatched when extra-close, delicate work was needed.
The "disavowed" comes from the fact that when a particularly harrowing mission, joined in by several different agencies each wanting a piece of the glory, went horribly wrong at the end, the word from the very top said someone or someones had to take the fall. The true facts clearly showed that the Razor's Edge team, being the closest to the unfortunate victims, were not to blame but facts have a way of disappearing when the CYA mentality sets in. The three members took the hit.
Apparently, payments under the table by the CIA to lessen the blow went with the ouster. Wanting to still be a service to their country, and frankly loving the work they had been doing, they started up their own little firm and began helping out civilians who desparately needed skilled operatives to rescue them.
The members of this elite team are:
Aaron Trent - the leader and the planner. He is a usually somber individual made even more so by an especially nasty shrew of an ex-wife whose love, if it ever was there, turned extremely hateful and who used their 8-year old son, Mike, as a weapon against Trent.
Adam Silk - the "finesser" of the team, this member is described as "Silk's jet black hair was slicked back with gel which, along with his whip-thin body and small ferrety eyes, gave the impression that the man might be a bit of a trickster - and a wily one at that." When a smooth talker was needed, Silk was usually the man.
Dan Radford - the tech wizard with the group. "Radford was the pretty boy of the team, the man with a girl in every port. His wife, Amanda, didn't mind a bit. She was a book publicist, and had a guy in every town. But somehow, they were still married." Radford might not be the best with everything electronic or digital but he was darned close and he knew those better well enough to ask for help when needed.
