Interesting fact: That story Connie tells Lucas about how Churchill allowed the Germans to bomb Coventry during the Blitz to prevent them from finding out the British had broken their codes is a myth.

In reality, what happened is that from the broken codes the British knew that a major attack was coming. The Germans used code words for the various cities in England, and these code words started with the same letter than the name of the city. For instance, London would be coded as 'Lederhosen'. With this particular attack, the code for the city started with a 'K', and the British couldn't figure out what the target was. Only when it was too late did they realise that Coventry is spelt with a 'K' in German.
