Brigitte en Acción: El documento Andreiev

This Spanish-language spy fiction serial by Lou Carrigan features Brigitte Montfort ("Baby"), a CIA field agent, and her lover Número Uno. The narrative opens with their peaceful lakeside retreat interrupted by helicopter arrival of CIA chief Pitzer and assistant Simón. Pitzer delivers urgent news: over 300 Soviet espionage agents have infiltrated the U.S. East Coast, distributed strategically in a mysterious "filter" operation. The Soviets brazenly conduct the operation with apparent indifference to CIA detection. Pitzer and his team cannot determine the operation's objective—whether preventing someone's entry or protecting something's arrival. Número Uno deduces they're likely intercepting a single target arriving by sea, possibly via Russian submarine. Brigitte proposes a pragmatic solution: return to New York and investigate. The narrative shifts to Soviet agents Sochvili and Kolchianov, positioned near Long Island as part of the surveillance network.
