A FEW DAYS LATER, Ricardo and I flew up to Toronto to meet the Cubans at an airport hotel. When we walked into the lobby, we noticed a conspicuous couple sitting at the center of the bar area staring at us—a tattooed man and a woman dressed like an extra in a 1980s Madonna music video. As we checked in, they walked over to where we were standing and stopped a few feet away; the man took out an iPhone, held it out in front of him, and took pictures of us. Then they walked off toward the elevators without saying a word. “Russians,” Ricardo said.
