Book excerpt: Looking at secret agents on television in the 1950s and 1960s, Michael Kackman explores how Americans see themselves in times of political and cultural crisis. From parodies such as The Man from U.N.C.L.E. and Get Smart to the more complicated situations of I Spy and Mission: Impossible, Kackman situates espionage television within the culture of the civil rights and women's movements and the war in Vietnam.
