Read the passage from The Strange Case of Dr. Jekyll and Mr. Hyde . "And now,” said Mr. Utterson, as soon as Poole had left them, "you have heard the news?” The doctor shuddered. "They were crying it in the square,” he said. "I heard them in my dining-room.” "One word,” said the lawyer. "Carew was my client, but so are you, and I want to know what I am doing. You have not been mad enough to hide this fellow?” "Utterson, I swear to God,” cried the doctor, "I swear to God I will never set eyes on him again. I bind my honour to you that I am done with him in this world. It is all at an end. And indeed he does not want my help; you do not know him as I do; he is safe, he is quite safe; mark my words, he will never more be heard of.” What can the reader infer from Dr. Jekyll’s behavior?
