A sense of social hierarchy prevented Mrs Munde from actually telling the lousy bastard to get out, so instead she began to think evil thoughts. She had once read an article on mind control, explaining that the best way to bend someone to your will was to think of a gooey mudlike substance called Cliff Richard and direct it at the object of your intent. Such were the marshmellow-suffocating properties of this image that the victim fell instantly into an undignified froth. Putty in your hands in fact. It didn't seem to work. The stranger was insensitive as well as intrusive. Mrs Munde gave it one last go till the kitchen air was thick with Cliff Richard. The stranger suddenly made a little squeaking noise and fell sideways.
