"In your friendship, certainly. But facts are facts, Watson, and, after all, you are only a general practitioner with very limited experience and mediocre qualifications. It is painful to have to say these things, but you leave me no choice." I was bitterly hurt. "Such a remark is unworthy of you, Holmes. It shows me very clearly the state of your own nerves. But if you have no confidence in me I would not intrude my services. Let me bring Sir Jasper Meek or Penrose Fisher, or any of the best men in London. But someone you MUST have, and that is final. If you think that I am going to stand here and see you die without either helping you myself or bringing anyone else to help you, then you have mistaken your man." "You mean well, Watson," said the sick man with something between a sob and a groan. "Shall I demonstrate your own ignorance? What do you know, pray, of Tapanuli fever? What do you know of the black Formosa corruption?" "I have never heard of either." "There are many problems of disease, many strange pathological possibilities, in the East, Watson." He paused after each sentence to collect his failing strength. "I have learned so much during some recent researches which have a medico-criminal aspect. It was in the course of them that I contracted this complaint. You can do nothing." "Possibly not. But I happen to know that Dr. Ainstree, the greatest living authority upon tropical disease, is now in London. All remonstrance is useless, Holmes, I am going this instant to fetch him." I turned resolutely to the door. Never have I had such a shock! In an instant, with a tiger-spring, the dying man had intercepted me. I heard the sharp snap of a twisted key. The next moment he had staggered back to his bed, exhausted and panting after his one tremendous outflame of energy. "You won't take the key from me by force, Watson, I've got you, my friend. Here you are, and here you will stay until I will otherwise. But I'll humour you." (All this in little gasps, with terrible struggles for breath between.) "You've only my own good at heart. Of course I know that very well. You shall have your way, but give me time to get my strength. Not now, Watson, not now. It's four o'clock. At six you can go." "This is insanity, Holmes." "Only two hours, Watson. I promise you will go at six. Are you content to wait?" "I seem to have no choice." "None in the world, Watson. Thank you, I need no help in arranging the clothes. You will please keep your distance. Now, Watson, there is one other condition that I would make. You will seek help, not from the man you mention, but from the one that I choose." "By all means." "The first three sensible words that you have uttered since you entered this room, Watson. You will find some books over there. I am somewhat exhausted; I wonder how a battery feels when it pours electricity into a non-conductor? At six, Watson, we resume our conversation."
