Published to mark the 40th anniversary of his death, The Man Who Was Saturday is Patrick Bishop's eye-opening and action-packed biography of Airey Neave - a World War II hero, spymaster and politician who was murdered in the House of Commons car park in 1979.
Examining the life, war and death of Airey, this book reveals how he was the first British officer to escape from Colditz and how (while using the code name 'Saturday') he became a key figure in the IS9 escape which helped hundreds of Allies out of Occupied Europe.
As well as getting mixed up in several great spy scandals, Airey was also a trained lawyer who served indictments on the Nazi leaders during the Nuremburg war trial. As if that wasn't enough, he was also the man who helped get Margaret Thatcher into power in 1975...
His death in 1979 is just as remarkable as his life. A bomb was placed beneath his car while he was driving up the ramp of the House of Commons underground car park, killing him instantly and although the murder was claimed by Irish Republican group the INLA, the killers have never been identified.
