The Buyer: The making and breaking of an undercover detective

Liam Thomas was an officer in the Met for over a decade, many of those years spent deep at the heart of Britain's most dangerous criminal enterprises in the murky world of undercover surveillance. Before him, his father had also been a police officer, a pillar of their small community.

Fighting corruption was Liam's life. But the murky world of undercover work teaches him that justice is far from black and white - and a family secret reveals that corruption is closer to home than he had ever expected. The revelations push him to the edge of his sanity - and then he discovers that his bosses are investigating him...

A thrilling memoir of a life lived amongst a world of corruption, justice and loyalties, this book tells the real story of the police's line of duty.
