Sleeper Cells, Ghost Stories and the Hunt for Putin's Agents. 'Russians Among Us' describes for the first time the story of deep cover spies in America and the FBI agents who tracked them. In intimate riveting detail, it reveals new information about today's spies - as well as those trying to catch them and those trying to kill them. In the summer of 2010 a group of Russian deep cover sleeper agents were arrested, and ten people, including glamorous, red-haired Anna Chapman, were swapped for four people held in Russia. At the time is was seen simply as a throwback to the Cold War. But that would prove to be a mistake.
