M’lud, it went like this. The cascading water turned the wheel. The wheel cranked the rope. I steadied the rope, which raised the barrel of bricks.
Unfortunately, the water ran out. The barrel was now heavier than I. It started down, jerking me off my feet.
Halfway up, I met the falling barrel, receiving a severe blow on the shoulder. When it hit the ground, the bottom burst, releasing the bricks.
I was now heavier than the barrel. I started downwards. The barrel was coming up, so I swung through the window like an action hero. Mrs Cuthbertson was very surprised. So too the man who wasn’t Mr Cuthbertson.
