Victor rigs the attic door with a feather, and when Nina and Fabian sneak up to find some strange wax cylinders (during Mick and Amber's getting together party), Victor knows that someone has been up there. Mara talks to Patrica in the girls bathroom about her liking Mick, and unknowing to the two of them, Amber hears the whole thing - eventually being fed up. Amber blows up with jealousy over Mara and Mick's friendship and demands to change rooms, sharing with Nina instead of Mara. Fabian and Nina take the wax cylinders to Fabian's uncle Ade who runs an antique shop and find out about the phonograph cylinders. Fabian remembers seeing an old phonograph in the attic. They resolve to return to the attic if they want to play the cylinders. Patricia overhears Victor talking to the Sergeant from the police station about Joy, and realizes the police are also involved in the conspiracy surrounding Joy's disappearance and becomes afraid of everything.

Mick finds out Mara cheated for him and falls out with her. Amber discovers a secret message written behind the wallpaper - "Help me, Sarah Frobisher Smythe." Fabian, Nina, and Amber record the cylinders onto a Dictaphone. The young girl on the recordings mentions a murder. They suspect that the girl may be a young Sarah. Amber and Nina go to the old people's home to visit Sarah and confirm that she is, in fact, the girl from the recordings. Amber comes up with a name for their gang - "Sibuna" (Anubis backwards). They make it official with a ceremony by the woods after which Fabian manages to open the puzzle piece, revealing a riddle. Meanwhile, Jason finds Joy's broken mobile phone at the school bins; he searches for more clues but finds nothing. Guest Star: Francis Magee
