Unfortunately for Penkovsky, his espionage activities drew the attention of the KGB. Despite operating with a degree of caution, he was ultimately betrayed—speculations linger about whether he was exposed due to a planted mole or other circumstances. In 1962, he was arrested, and in May 1963, after a show trial, he was executed.
