When Sir Peter Good suspects that his cleaner is stealing, he sets a trap for her. A large amount of money is placed in a silver cup on a shelf over the window. A little later the money duly disappears and the cleaner admits her guilt. Assisted by his gardener, the girl is sentenced to a good spanking, to be administered by Sir Peter and the gardener. Not long later, the bottom of the wretched girl glows red. (SP153)
