As I entered, a sallow Malay attendant had hurried up with a pipe for me and a supply of the drug, beckoning me to an empty berth.

“Thank you. I have not come to stay,” said I. “There is a friend of mine here, Mr. Isa Whitney, and I wish to speak with him.”

There was a movement and an exclamation from my right, and peering through the gloom, I saw Whitney, pale, haggard, and unkempt, staring out at me.

“My God! It’s Watson,” said he. He was in a pitiable state of reaction, with every nerve in a twitter. “I say, Watson, what o’clock is it?”

“Nearly eleven.”

“Of what day?”

“Of Friday, June 19th.”

“Good heavens! I thought it was Wednesday. It is Wednesday. What d’you want to frighten a chap for?” He sank his face onto his arms and began to sob in a high treble key.

“I tell you that it is Friday, man. Your wife has been waiting this two days for you. You should be ashamed of yourself!”

“So I am. But you’ve got mixed, Watson, for I have only been here a few hours, three pipes, four pipes—I forget how many. But I’ll go home with you. I wouldn’t frighten Kate—poor little Kate. Give me your hand! Have you a cab?”

“Yes, I have one waiting.”

“Then I shall go in it. But I must owe something. Find what I owe, Watson. I am all off colour. I can do nothing for myself.”
