Dillon Masters is a computer genius, his IQ is off the charts. He was thrown out of MIT for hacking the physics department's computers and revising most of the accepted theorems they were working from. They threw him out of school, but kept using his revisions. Three years ago, Agent Jones busted Dillon and made a deal with him — he stays out of the Agency computer system and she doesn't toss him in jail. A bond of sorts was formed and these days Jones still reaches out to Dillon when she needs high tech, off-the- books. Dillon is brilliant, but with his brilliance, comes a quirkiness and a healthy streak of larceny, which means that Jones and XIII never know exactly how far they can trust him.
