Safecracker Hints

What's inside the filing cabinet?

  • 1) A note with a diagram of a clock motor, which says:

    Clock Motor
    For opening doors

    1. The drive must be wound up by use of a crank.
    2. The clock motor is set in motion.
    3. The rotating chain-drive cylinder draws in the chain and opens the door.
    4. The stone floor panel is depressed when trod upon, releasing the catch and closing the door.
