Faceman/Snoop Class Guide

From the back of the book:

Waking every day in the heart of corruption and sleeping on a bed of lies, no one understands the many enemies of freedom and peace better than the Agency's consummate masters of global intelligence, its facemen and snoops. Invisible troops along a covert battlefront few of us can fathon, these innovative investigators are the ultimate secret agents, the faceless and romantic relics of a bygone era. The Spycraft Faceman/Snoop Class Guide thrusts you into this new arena of excitement, delving into the often neglected low-impact end of espionage, where knowledge owns the past, and intelligence rules the future.
