For two years, Donna McLean lived a life of bliss with her boyfriend, Carlo. But her great love story wasn't just built on lies - it was one. Because Carlo wasn't a bike-obsessed Italian locksmith at all; he was a British police officer, part of a unit that had worked undercover for years to infiltrate activist groups across the country.
