other markets for a worldwide total of $15.7 million. Historical accuracy The film and, by association, the book have attracted criticism for their portrayal of the Polish role in Enigma decryption. The historian Norman Davies argues that in the film the fictitious traitor turns out to be Polish, but only slight mention is made of the contributions of prewar Polish Cipher Bureau cryptologists to Allied Enigma decryption efforts, but historically, the only known traitor active at Bletchley Park was British spy John Cairncross, who passed crucial secrets to the Soviet Union. The film hints that Dougray Scott's character, the brilliant Cambridge mathematician Thomas Jericho is the main code-breaker at Bletchley, equating him with Alan Turing, the original creator of the British Bombe, with the words of Mr Wigram, played by Jeremy Northam: "But what if someone tells them just how we do do it? Your thinking machine, clackity-clack, day and night, programmed with a menu, thanks to your big brain, that reduces the odds to just a few million-to-one until it locks on to the winning combination. There goes the war…” Of course Jericho is a totally fictional character, given that Turing was homosexual and only had a platonic relationship with his short-lived fiancé Joan Clarke, who knew about his sexual orientation. In reality it was unlikely that Turing was involved in code-breaking the Naval four-rotor Enigma Shark in 1943. Notes by Tony Sale do not mention Turing as the "someone in Bletchley Park [who] realised that Short Weather Signals were sent in the three wheel mode" and explained "the Central Met. Station had collated the U-Boat and other reports, [and] they broadcast a general synoptic in their own Met. Code", which used the standard International Met. Code further encoded using bigram tables, as discovered by Mr Archer from the Met. section of Bletchley Park. According to Hugh Alexander, from June 1943 Joan Clarke, Mahon, Pendered and Noskwith were responsible for the whole of the cryptographic work until the end of the war. Strangely, Joan Clarke is not present in the film as none of the team of cryptanalysts are female. In the film, Cave, from Naval Intelligence, played by Matthew Macfadyen, mentioned Fasson and Grazier gave their lives to rescue the code books from a sinking submarine. There were actually three men who retrieved the books: First Lieutenant Anthony Fasson, Able Seaman Colin Grazier and 16-year-old Tommy Brown from
