Did you ever remark that door?" he asked; and when his companion had replied in the affirmative, "It is connected in my mind," added he, "with a very odd story." I think you might have warned me," returned the other with a touch of sullenness. "But I have been pedantically exact, as you call it. The fellow had a key; and what's more, he has it still. I saw him use it not a week ago." But Lanyon's face changed, and he held up a trembling hand. "I wish to see or hear no more of Dr. Jekyll," he said in a loud, unsteady voice. "I am quite done with that person; and I beg that you will spare me any allusion to one whom I regard as dead."

Lanyon’s letter explains how he received a note from Jekyll instructing him to retrieve a drawer and its contents from his laboratory and to wait for a man at midnight, who would then reveal everything to Lanyon. Hyde visits Lanyon and concocts a formula from the contents of the drawer. Lanyon watches in horror as Hyde drinks the formula and transforms into Jekyll before his eyes. Utterson nurtures a close friendship with Mr. Enfield, his distant relative and likewise a respectable London gentleman. The two seem to have little in common, and when they take their weekly walk together they often go for quite a distance without saying anything to one another; nevertheless, they look forward to these strolls as one of the high points of the week. My reason wavered, but it did not fail me utterly. I have more than once observed that in my second character, my faculties seemed sharpened to a point and my spirits more tensely elastic; thus it came about that, where Jekyll perhaps might have succumbed, Hyde rose to the importance of the moment. My drugs were in one of the presses of my cabinet; how was I to reach them? That was the problem that (crushing my temples in my hands) I set myself to solve. The laboratory door I had closed. If I sought to enter by the house, my own servants would consign me to the gallows. I saw I must employ another hand, and thought of Lanyon. How was he to be reached? how persuaded? Supposing that I escaped capture in the streets, how was I to make my way into his presence? and how should I, an unknown and displeasing visitor, prevail on the famous physician to rifle the study of his colleague, Dr. Jekyll? Then I remembered that of my original character, one part remained to me: I could write my own hand; and once I had conceived that kindling spark, the way that I must follow became lighted up from end to end.A year later, the police summon Utterson after they discover a note with his name on it on the body of Sir Danvers Carew, a member of Parliament and client of Utterson that Hyde murdered. Utterson leads the police to Hyde’s apartment, and while he is nowhere to be found, they learn that Hyde has an account at a local bank. For weeks, the police expect Hyde to appear at the bank to withdraw money, but he never comes. Chapter 5

The pair walked on again for a while in silence; and then "Enfield," said Mr. Utterson, "that's a good rule of yours." Mr. Utterson sighed deeply but said never a word; and the young man presently resumed. "Here is another lesson to say nothing," said he. "I am ashamed of my long tongue. Let us make a bargain never to refer to this again."

He is not easy to describe. . . . And it’s not want of memory; for I declare I can see him this moment. Analysis The next day, came the news that the murder had not been overlooked, that the guilt of Hyde was patent to the world, and that the victim was a man high in public estimation. It was not only a crime, it had been a tragic folly. I think I was glad to know it; I think I was glad to have my better impulses thus buttressed and guarded by the terrors of the scaffold. Jekyll was now my city of refuge; let but Hyde peep out an instant, and the hands of all men would be raised to take and slay him. Yes, I preferred the elderly and discontented doctor, surrounded by friends and cherishing honest hopes; and bade a resolute farewell to the liberty, the comparative youth, the light step, leaping impulses and secret pleasures, that I had enjoyed in the disguise of Hyde. I made this choice perhaps with some unconscious reservation, for I neither gave up the house in Soho, nor destroyed the clothes of Edward Hyde, which still lay ready in my cabinet. For two months, however, I was true to my determination; for two months, I led a life of such severity as I had never before attained to, and enjoyed the compensations of an approving conscience. But time began at last to obliterate the freshness of my alarm; the praises of conscience began to grow into a thing of course; I began to be tortured with throes and longings, as of Hyde struggling after freedom; and at last, in an hour of moral weakness, I once again compounded and swallowed the transforming draught. Mr. Utterson again walked some way in silence and obviously under a weight of consideration. "You are sure he used a key?" he inquired at last. Yes, I know," said Utterson; "I know it must seem strange. The fact is, if I do not ask you the name of the other party, it is because I know it already. You see, Richard, your tale has gone home. If you have been inexact in any point you had better correct it."
