An episode title for a Series 7 episode may have been revealed.
According to his CV, Director of Photography Simon Dennis is working on an episode directed by Colm McCarthy (believed to be Steven Moffat’s Series 7: Part 2 opener). The CV states that the episode is titled:
The Bells of Saint John.
The only thing we can think of is the St John Ambulance logo on the TARDIS. But a Google search also reveals a line in the “Oranges and Lemons” nursery rhyme: Pokers and tongs, Say the bells of St. John’s.
Some further possibly related information is included below:
The Chapel of St John is the oldest church in London and situated in the Tower of London on the second floor of the White Tower. The Tower of London was built in 1077 – 97 by William the Conqueror. A door from the Great Chamber on the second floor leads to the north aisle of the Chapel of St John the Evangelist. A gruesome discovery was made under the stairs leading to the chapel. The remains of the bodies of the two Little Princes, Edward V and his younger brother Richard, Duke of York were found who were reputedly killed on the orders of their uncle the Duke of Gloucester, afterwards Richard III ( although some scholars name Henry VII as the culprit). The Tower of London was used as a prison for many years and the “Pokers and Tongs” refer to the instruments of torture which were used there!
This is not a confirmed episode title and is more than likely a working title. If there's any more news regarding this then we will get it posted straight away!
