Escape from Lord Baden Powell's House
Your patrol has arranged for a private tour of a Manor House in England. The old house of Lord Baden Powell. You arrive at the arranged time, but no-one is there to meet you. Your patrol leader knocks loudly on the front door, but no-one responds.
You run out to the main gate to leave, but the main gate is locked and the wall too high to climb. You are now trapped in the grounds.
