No doubt the feat was easy to Mr. Utterson; for he was undemonstrative at the best, and even his friendship seemed to be founded in a similar catholicity of good nature. It is the mark of a modest man to accept his friendly circle ready made from the hands of opportunity; and that was the lawyer's way. His friends were those of his own blood or those whom he had known the longest; his affections, like ivy, were the growth of time, they implied no aptness in the object. Hence, no doubt the bond that united him to Mr. Richard Enfield, his distant kinsman, the well known man about town. It was a nut to crack for many, what these two could see in each other, or what subject they could find in common. It was reported by those who encountered them in their Sunday walks, that they said nothing, looked singularly dull and would hail with obvious relief the appearance of a friend.
I do not blame our old friend, Jekyll wrote, but I share his view that we must never meet. I mean from henceforth to lead a life of extreme seclusion; you must not be surprised, nor must you doubt my friendship, if my door is often shut even to you. You must suffer me to go my own dark way. I have brought on myself a punishment and a danger that I cannot name. If I am the chief of sinners, I am the chief of sufferers also. I could not think that this earth contained a place for sufferings and terrors so unmanning; and you can do but one thing, Utterson, to lighten this destiny, and that is to respect my silence. Utterson was amazed; the dark influence of Hyde had been withdrawn, the doctor had returned to his old tasks and amities; a week ago, the prospect had smiled with every promise of a cheerful and an honoured age; and now in a moment, friendship, and peace of mind, and the whole tenor of his life were wrecked.
Dear Lanyon, You are one of my oldest friends; and although we may have differed at times on scientific questions, I cannot remember, at least on my side, any break in our affection. There was never a day when, if you had said to me, 'Jekyll, my life, my honour, my reason, depend upon you,' I would not have sacrificed my left hand to help you. Lanyon my life, my honour, my reason, are all at your mercy; if you fail me tonight, I am lost. You might suppose, after this preface, that I am going to ask you for something dishonourable to grant. Judge for yourself.
