Read the following passage and answer the questions.
Everyone thought that Horace Denby was a good and honest citizen. He was about fifty years old and unmarried, and he lived with a housekeeper who worried over his health. In fact, he was usually very well and happy, except for attacks of hay fever in summer. He made expensive locks and was successful enough at his business to have two helpers. Yes, Horace Denby was good and respectable – but not completely honest.
Fifteen years ago, Horace had served his first and only sentence in prison for stealing jewels. The priest at the prison had liked Horace – everyone did – and had tried to help him to live an honest life. But Horace did not want to become honest. He only wanted to make sure that his dishonesty never got him into trouble again.
