Mr. John Greatorex was very wealthy, and very obstinate. He had made a large fortune as a manufacturer of chemicals, but disclaimed any knowledge of chemistry.

Consequently, when his new motor-car arrived, he saw no necessity to take a chauffeur with him on its trial spin. He was like a child with a new toy, jealous of participation.
