I was raised in Hertfordshire and 'enjoyed' an unspectacular career at Berkhamsted School. After leaving school at 16, I did a variety of jobs until I was inspired to return to education by the East European Revolutions of 1989. Thereafter, I went to night school and enrolled in the School of Slavonic and East European Studies of the University of London in 1990 to study history and politics. I graduated with an MA in 1994 and have since studied at the universities of Düsseldorf and Strathclyde, failing to gain a PhD at both.
I began my writing career working for Professor Norman Davies. I collaborated with him on many of his recent publications, including Europe: A History, The Isles: A History, and Rising '44. This working relationship culminated in 2002 with the publication, in three languages, of a co-authored study of the history of the city of Wrocław (the former German Breslau) entitled Microcosm: Portrait of a Central European City.
2006 saw the publication of Killing Hitler, my first solo book. An account of the numerous attempts on Hitler's life, it was a critical and commercial success and has been published in numerous other languages, including German, Spanish, Chinese, Italian and Japanese.
My most recent book - entitled Berlin at War - is a social history of Berlin during World War Two, which was published in the summer of 2010. Based on first-hand material such as unpublished diaries, memoirs and interviews, the book gives a unique "Berlin-eye view" of the war. It has been well-recieved, with positive reviews in most major publications. Writing in the Financial Times, Andrew Roberts said of it that: "Few books on the war genuinely increase the sum of our collective knowledge of this exhaustively covered period, but this one does."
