Maxwell Smart always "missed it by that much," but some of those dopey spy shows of the '60s were right on the money. "Many of the devices first seen in movies and on TV actually came about," says Robert Wallace, former head of the CIA's covert skunk works, the Office of Technical Services. "Remember the Cone of Silence? We built shielded enclosures that did the same thing. And the pen communicator in The Man From U.N.C.L.E.? That evolved, 10 years later, into short-range agent communication." Wallace, who was basically the agency's real-life Q, reveals these gadgets and more in his new book, Spycraft, the first comprehensive look at the technical achievements of American espionage from the 1940s to the present. "Here's the laboratory," Wallace used to tell new recruits. "The only thing that is going to limit what you can do is your imagination." It seems they took him at his word.

1940s Cigarette gun
Lipping this pistol disguised as a cigarette, an agent could easily release the safety pin. Rotating the filter end counterclockwise armed the gun, and a push of the thumb caused it to fire a single .22-caliber bullet. It really worked.
