Sorry for the bad quality, I’m still getting used to photoshop!
During the case of the Blind Banker, Sherlock returns to 221b Baker Street to find someone has broken in and sprayed another message on his wall. While John is out trying to find someone who can break the code, Sherlock is busy looking at samples when he hears a strange noise and faint glow from the next room. He runs out of the kitchen and finds that the message has been translated into English, but the paint is not fresh, it appears to be the same paint as before. This can only mean one thing. The Tardis translation circuit is working. The Doctor is back.
