Muko could hardly wait to tell his friends what he'd heard. He pulled them together so that their heads were almost touching and spoke to them in an excited whisper.
“You'll never believe what I heard those teachers saying. They were talking about some kind of a mystery, which they called a riddle. The Machinists and their teacher, and another teacher that I didn't recognise, are trying to solve it.”
“Wow,” breathed Gelio.
“You know I told you Pythagoras was talking about something mysterious?”Muko continued, still in the same whisper. “Well I think he's in with the Machinists because he seemed all buddy-buddy with the Machinists' teacher. But there's something else I found out. It looks like the riddle's got to do with some kind of sculpture.”
“How can we find out more?” wondered Gelio.
“I know!” Everyone turned to look at Paidia. “You know
I like books ...”
“Yeah, you're a regular bookworm,” ribbed Gelio.
