Corrected entry: 'City of Death' is set very definitely in Paris in 1979. There's even location filming in Paris to establish this (it was the first time ever a Doctor Who story was filmed outside the UK). Yet EVERYONE in this story speaks English. Even the TV News report in the cafe (reporting that the Mona Lisa had been stolen) was in English. Couldn't the film makers find anyone in Paris who spoke French? After all there's about two million people to choose from.
