进阶段-化身博士（简写版第25集）

一，原文文章：

At midnight exactly there was a knock on my door． A short man was standing in the shadows．
'Are you from Doctor Jekyll？'I asked．He bent his head．Although I could not see his face，there was something unpleasing about him and I was glad I had a weapon．I invited him into the house and there， in the bright light， I took a closer look at him．
His appearance was extremely strange． His clothes were well made and expensive， but they were far too large for him． He looked like a child wearing his father's clothes， but there was nothing childlike about this man． He was short， as I have said， but very strong. At the same time there was alook of sickness and horror about him，and his face was a mask of pain， violence and hate．As a doctor I could pernaps feel sorry for him；as a mau I felt only fear and dislike．
'Have you got it？'said the stranger impatiently，reaching out his hand and touching my arm． His touch made my blood run cold．I shook off his hand．'Come， sir，' I said calmly．'Sit down and introduce yourself．'
'I apologize， Doctor Lanyon，'the stranger said more politely．'Doctor Henry Jekyll sent me here on an important matter．I have to collect something from you．'
I gave him the box．He took it with trembling hands．' At last！'he cried．He turned to me．His face was deathly pale．'Have you a medicine glass？'he asked．
I gave it to him．He put a little of the red liquid in the glass and added a packet of powder．A small cloud of smoke rose from the glass and the colour of the liquid changed from red to purple， and from purple to a watery green．The stranger put the glass down on the table and looked sharply at me．
'And now，'he said，'choose carefully．You can leave the room now ．Or you can stay and experience something new，something unknown to science． You can be rich，famous and successful，if only you will believe'
He put the glass to his lips and drank the liquid．His whole body shook and jumped and he almost fell．He held onto the edge of the table， breathing fast through his open mouth． AsI watched，his whole body seemed to change．He seemed to become taller， fatter-his face turned black and its shape began to change…The next moment I jumped back against the wall，trembling with fear and horror．There before my eyes， pale and shaken and sick， stood Henry Jekyll！
I cannot make myself write down the things that Jekyll，with tears in his eyes， confessed to me that night
