Undercover: The True Story of Britain's Secret Police - Tapa blanda

Undercover lays bare the deceit, betrayal and cold-blooded violation, practised again and again by undercover officers - troubling, timely and brilliantly executed. (Henry Porter)

Doggedly written and researched by Guardian journalists Rob Evans and Paul Lewis, the revelations in its pages are genuinely explosive ... it's the steady accumulation of detail that's so compelling. The testimony of person after person who was taken in, deceived, gulled, who knew the officers for years - who thought of them as best friends, or lovers, or life partners, or the father of their children, who had no inkling that they were part of an elaborate state-sponsored spy-ring that intruded on the most intimate parts of their lives. (Carole Cadwalladr Observer)

Undercover is not just a book; it's a sensation ... it's terrific and important journalism. (Jenni Russell Sunday Times)

Were these stories not real, they would read like an airport thriller ... Undercover compels the reader throughout, which is a testament to the investigative and writing skills of Evans and Lewis ... The work of these authors is one of the best arguments in favour of a free press you'll ever read. (Alan White New Statesman)

What makes this book so utterly absorbing is not the politics or policing, but the people. (David Aaronovitch The Times)

With luck, the grotesqueries revealed in this powerful book will fire some of the old free and radical British spirit again. (Bernard Porter Guardian)
