[In an envelope is a photograph. The photograph is an up close shot of a brick, obviously part of a wall. However, because of the focus on the brick, there is little other detail to be found within the picture itself. However, when the photograph is turned over, there is writing on the back. And for the record, the handwriting does NOT belong to the Master. In case you thought he'd make this easy for you. :P The message reads as follows:]
Strong yet worn If walls could talk, these would scream Many have come and gone under this roof What am I?
[Yay riddles. And I sort of suck at writing them, but oh well. A more specific clue will follow Monday. But all the clues that will be given will lead to dead ends, and you will know when you get there because there will be a post with a graphic. Which I need to make. But for now, HAVE FUN WITH THIS DOCTORS! :D]
