Winter Solstice

As the People know, mind-wipes don't always take with Mud-Men. Variations in brain chemistry mean that some humans are immune.

It was unfortunate that the night-watchman employed by English Heritage at Stonehenge was one of those rare individuals. Luckily for the LEP, no-one believed his assertions that he'd seen a swarm of fairies, especially as he kept breaking into an incredibly long song about pizzas. His employers decided to send him on indefinite leave because of problems with his mental health.

However, it hasn't turned out too badly for him. Several fast food chains want to offer him a contract.
