While Patricia manages to decode a secret message from Joy arranging to meet after the play, Nina attempts to break into Victor's safe to steal the puzzle.

With Trudy gone, Victor installs security cameras to spy on the kids. Mara takes on Mick in a sports quiz.

Mrs Andrews is keen to try to rescue Patricia, but Victor forbids it, and Mr Sweet is too weak to disagree.

The gang work out they could be searching for the Cup of Ankh, and plot to steal the puzzle back from Victor. Plus, Patricia spots Joy in the audience at the play.

Nina is trying to distance herself from the gang but still can't help solving the latest riddle.

The gang reads a secret message hidden in the dictionary: their next clue. While trying to crack it, though, Victor forces Nina and Victor to hand the puzzle over.
