One morning in December 1965, the C.I.A. station chief in Montevideo, Uruguay, went to the city’s Police Headquarters to tell security officials about a disinformation campaign the Americans were planning in their country. Like the rest of Latin America, Uruguay was a Cold War battleground, and Washington was eager to discredit a left-wing insurrection — in this case, by concocting rumors that Soviet agents had infiltrated Uruguayan labor unions. Accompanying the C.I.A. chief was a 30-year-old case officer named Philip Agee, who was helping coordinate the plot.
As the Uruguayans reviewed the C.I.A.’s plans, a soccer match played on the radio. Soon, however, a different noise intruded. “I began to hear a strange low sound which, as it gradually became louder, I recognized as the moan of a human voice,” Agee later wrote. At first, he thought it was a street vendor outside. But the sound persisted, and it became clear that it was coming from the room above.
“The moaning grew in intensity, turning into screams,” Agee wrote. “By then I knew we were listening to someone being tortured.” Agee was already harboring moral qualms about his work, and to his horror, he suspected — correctly, he soon learned — that the voice belonged to a Communist operative whose name Agee himself had supplied to the Uruguayans. “All I wanted to do was get away from the voice,” he recalled.
