Jack Rock stood in his shop in High Street. He was not very often to be seen there nowadays; he bred and bought, but he no longer killed, and rarely sold, in person. These latter and lesser functions he left to his deputy, Simpson, for he had gradually developed a bye-trade which took up much of his time, and was no less profitable than his ostensible business. He bought horses, "made" them into hunters, and sold them again. He was a rare judge and a fine rider, and his heart was in this line of work.
