As the minotaur speaks english, you talk to him again. "Push your fingers together inside the puzzle!"
He does so, and the trap falls to the ground. "I'm free!" he cries "Thankyou, thankyou. You've very clever." He goes up to the hedge "I hope you've clever enough to find your way out, and soon."
"What do you mean?" you ask
"I was a human called Terry when I came in, just like you. That must have been 3 months ago. The maze turned me into this creature, and I haven't finished." He holds his huge foot up to the hole in the hedge "Soon my feet will turn to hooves." he says, wriggling his toes "Then I'll lose the power of speech, and finally my human memories. The same will happen to you if you don't find your way out."
"That's terrible!" you say.
"That's not the worse thing." sighs Terry "There can only be one minotaur in the maze. If you change, I become a full bull and sold at the cattle market. Then you will wander the maze until someone replaces you. I wasn't the first minotaur, but I hope I'm the last. That's why they put the finger trap on me. I was too close to finding my way out."
