"You are proud of your brains, Holmes, are you not? Think yourself smart, don't you? You came across someone who was smarter this time. Now cast your mind back, Holmes. Can you think of no other way you could have got this thing?"
"I can't think. My mind is gone. For heaven's sake help me!"
"Yes, I will help you. I'll help you to understand just where you are and how you got there. I'd like you to know before you die."
"Give me something to ease my pain."
"Painful, is it? Yes, the coolies used to do some squealing towards the end. Takes you as cramp, I fancy."
"Yes, yes; it is cramp."
"Well, you can hear what I say, anyhow. Listen now! Can you remember any unusual incident in your life just about the time your symptoms began?"
"No, no; nothing."
"Think again."
"I'm too ill to think."
