What better cover for a government spy than to claim retirement and run a museum? E.

KGB agents planted this device in the heel of a U.S. ambassador's shoe in Moscow in the 1960s. The concealed transmitter, microphone, and batteries turned him into a walking radio station.
7. Poison Gas Gun
Created by the KGB in the 1950s, this double-barrel gun contained vials of prussic acid. When fired in the victim's face, the vials were crushed and the acid converted into fatal
