What do you do with a hundred thousand idle spies?

By 1990 the Berlin Wall had fallen and the East German state security service folded. For forty years, they had amassed more than a billion pages in manila files detailing the lives of their citizens. Almost a hundred thousand Stasi employees, many of them experienced officers with access to highly personal information, found themselves unemployed overnight.

This is the story of what they did next.

Former FBI agent Ralph Hope uses present-day sources and access to Stasi records to track and expose ex-officers working everywhere from the Russian energy sector to the police and even the government department tasked with prosecuting Stasi crimes. He examines why the key players have never been called to account and, in doing so, asks if we have really learned from the past at all. He highlights a man who continued to fight the Stasi for thirty years after the Wall fell, and reveals a truth that many today don't want spoken.

The Grey Men comes as an urgent warning from the past at a time when governments the world over are building an unprecedented network of surveillance over their citizens. Ultimately, this is a book about the present.
