A story of wartime intelligence, super-power relations and spies and their handlers - seen through the experience of Melita Norwood.

The methods developed by British intelligence in the early twentieth century still resonate today, like before the Second World War, focused on immediate threats posed by subversive, clandestine networks against a backdrop of shifting great power politics.

A compelling new narrative about how two Great Powers of the early twentieth century did battle, both openly and in the shadows.

The formation of state surveillance and the emergence of institutionalized political policing in late Victorian and Edwardian Britain.

One of the Irish Times' Books of the Year, 2008
Rebellion, partition and a messy peace settlement ensured that Ireland was a constant thorn in Britain's side after 1916. Britain was confronted by the bombs and bullets of militant republicans, the clandestine intrigues of foreign powers and the strategic dangers of Ireland's wartime neutrality - a final, irrevocable step in the country's difficult transition to independence.
Using newly-opened archives, this book reveals for the first time how the British intelligence system responded to these threats. It lifts the lid on the underground activities of Britain's secret agencies - MI5, MI6/SIS and the Special Branch. It puts secret intelligence in the context of the government's other sources of information and explores how deep-rooted cultural stereotypes distorted intelligence and shaped perceptions. And it shows how, for decades, British intelligence struggled to cope with Ireland but then rose to the challenge after 1940, largely because the Dublin government began to share its secrets. The author casts light on characters long kept in the shadows - IRA gunrunners, Bolshevik agitators, Nazi agents, Irish loyalists who acted as British spies. His compelling book fills a gap in the history of the British intelligence community and helps explain the twists and turns of Anglo-Irish relations during a time of momentous change.

The Isokon building, Lawn Road Flats, in Belsize Park on Hampstead's lower slopes, is a remarkable building. The first modernist building in Britain to use reinforced concrete and architecture, its construction demanded new building techniques. But the building was as remarkable for those who took up residence there as for the application of revolutionary building techniques. There were 32 Flats in all, and they became a haunt of some of the most prominent Soviet agents working against Britain in the 1930s and 40s, among them Arnold Deutsch, the controller of the group of Cambridge spies who came to be known as the "Magnificent Five" after the Western movie The Magnificent Seven; the photographer Edith Tudor-Hart; and Melita Norwood, the longest-serving Soviet spy in British espionage history. However, it wasn't only spies who were attracted to the Lawn Road Flats, the Bauhaus exiles Walter Gropius, László Moholy-Nagy and Marcel Breuer; the pre-historian Gordon Vere Childe; and the poet (and Bletchley Park intelligence officer) Charles Brasch all made their way there. A number of British artists, sculptors and writers were also drawn to the Flats, among them the sculptor and painter Henry Moore; the novelist Nicholas Monsarrat; and the crime writer Agatha Christie, who wrote her only spy novel N or M? in the Flats. The Isokon building boasted its own restaurant and dining club, where many of the Flats' most famous residents rubbed shoulders with some of the most dangerous communist spies ever to operate in Britain. Agatha Christie often said that she invented her characters from what she observed going on around her. With the Kuczynskis - probably the most successful family of spies in the history of espionage - in residence, she would have had plenty of material.
