I was raised in Hertfordshire and 'enjoyed' an unspectacular career at Berkhamsted School, before being inspired to return to education by the East European Revolutions of 1989. Thereafter, I 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, cunningly avoiding gaining a PhD at either.
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 Based on first-hand material such as unpublished diaries, memoirs and interviews, the book gives a unique "Berlin-eye view" of the war.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."
My new book, published in August 2014, is The Devils' Alliance, a history of the Nazi-Soviet Pact, one of the few remaining unexplored areas in the history of World War Two. It is published to coincide with the 75th anniversary of the Pact's signature, in August 1939.
