House of Cameras / House of Numbers

Summary
With Trudy gone, Victor installs security cameras to spy on the kids. Mara takes on Mick in a sports quiz, defeating him - but having proved herself, she offers to help with his training program. Nina finds an article on Tutankhamen's treasure and the original owners of Anubis House, who were implicated in stealing something from his tomb that was never found. After pressure from Mick's Dad, Victor is forced to remove the cameras and reinstate Trudy. The next riddle leads the gang to look underneath the stairs for something "beleathered and clasped" and there they stumble across a photograph of Victor from the 1920's looking exactly the same as he looks now.
