Seeing his daughter slowly die, coupled with his infinite sadness and misery, the clockmaker becomes a recluse to the tower of the castle and begins to build something behind closed doors, not even his daughter knows what he’s up to. For five years, she only sees him briefly at meal-times before locking himself up in the tower once again......Did he have a bathroom in the tower?Yes, Jack. A big one! En-suite! Power-shower and spa! Where was I!?
