In 1981, amid the volatile post-revolutionary landscape of Tehran, a high-ranking KGB major identified as Vladimir Kuzichkin met secretly with a British MI6 officer. The clandestine encounter, held in a bathroom at the British Embassy to mask their conversation, revealed Kuzichkin's decision to defect due to profound personal and professional anxieties.

Kuzichkin, a towering figure at 6ft 4in, was tasked with liaising with Iranian communists and was privy to a Soviet plot to destabilize the clerics in power and install a pro-Soviet regime. The potential success of this plan posed a significant threat to the West, potentially giving the Soviet Union control over crucial warm-water ports and oil fields.

However, Kuzichkin's primary motivation for seeking asylum and offering this critical intelligence was his struggle with erectile dysfunction. He believed Western medicine could offer a cure for the condition that was causing him significant distress and impacting his marriage. He confided in the MI6 officer, "In the West, there must be pills, yes? Western medicine is superior to Russian." The officer agreed to help, leading to Kuzichkin's recruitment as a double agent, codenamed Redwood by MI6.

Kuzichkin, described as a shy and awkward individual in his early thirties, was married to Galina. Despite a seemingly ideal KGB profile and a deep affection for his wife, he harbored growing disillusionment with the Soviet system, viewing party officials as hypocritical and the KGB as riddled with corruption. He also expressed contempt for Soviet leader Leonid Brezhnev, whom he believed was also suffering from impotence.

His posting in Tehran proved to be exceptionally stressful. He felt constantly under surveillance by Iranian intelligence and struggled with the psychological strain of espionage, including running agents codenamed Konrad and Evi and managing secure communication channels. The pressure was exacerbated by the ongoing executions and political maneuvering within Iran, and the involvement of the Tudeh party, the Iranian communist party he was tasked to liaise with, in the violence.

Adding to his turmoil, Kuzichkin's personal life was deeply affected by his impotence. The condition intensified his performance anxiety, leading to further failures in intimacy with his wife, Galina, who grew increasingly distressed and, at times, angry. His attempts to regain his virility, including an encounter with an Aeroflot stewardess, proved unsuccessful, deepening his humiliation.

The situation worsened when his agents, Konrad and Evi, were arrested in Switzerland and subsequently revealed their KGB identities. This placed Kuzichkin directly in the line of fire, with the potential for his role as their handler to be exposed to Moscow, which would likely result in severe repercussions for his career. It was at this critical juncture that the proximity of the British Embassy, and the presence of a new MI6 head of station, presented Kuzichkin with what he saw as a potential lifeline and an opportunity to escape his increasingly dire circumstances. This led to the meeting where his defection was initiated, driven by both geopolitical stakes and profound personal vulnerability.
