“If a Romeo wants to recruit women, Wolf told Melton once, ‘you don’t go to them, have them come to you. You become the center of the party, you buy the drinks, you tell the jokes. You’re the life of the party. She will come to you. And then naturally that will make it easier.’ The next step in East Germany’s playbook was to escalate the relationship. The agent would propose marriage and later reveal to his wife that he was a spy — but for a friendly country (like Canada!). The finishing touch was for the agent to explain that he would have to be recalled, ruining their precious relationship, unless the wife could cough up some information to satisfy the bosses back home.”
