Although the story is set in rural England, the map Tony picks up in the Police Station appears to show a grid-style US city.
In the beginning of the episode, Marcel chides Henri for suggesting that one of his less favorite forgeries be used in a con. Marcel points out that the original is in the Louvre. He states the Flemings and the Sinclairs don't steal from museums. Later in the episode, when Marcel is interviewing the retiring Henri's replacement, she claims that one of her forgeries was sold to the Berlin museum and Marcel doesn't seem to have a problem with it.
