“Why did you send for me?” Mason asked.

“I’m coming to it. Don’t interrupt me. When I get started, let me go. And don’t make me repeat. It makes me nervous to have to repeat. Where was I? Oh, yes, publicity. I’ll tell you why I can’t stand any publicity. I’m hiding. They’re trying to murder me. Wouldn’t be surprised if this murder downstairs was because some hired assassin got his numbers mixed. I used the greatest care getting this flat. It’s an ideal location for what I want. But I made one mistake. I should have rented the lower flat as well, and put Gow Loong in there. But when I moved in, the lower flat was untenanted and had been for over a year. Neighborhood’s gone to hell, but they still want too much money for their rentals. I rented this place, moved in at night...”

“Why didn’t you take the lower apartment for yourself?” Mason asked. “The stairs must make a difference.”

“Don’t make any difference at all,” Karr said. “Can’t go any place except in a wheelchair. Have no desire to go out of doors except to get a little sunlight. There’s a fine balcony here on the south and west side. I can get out there and get the sunlight. That’s why I like the place. No buildings over on the south side to shut off the sunlight. That big old-fashioned mansion over on the north literally blankets the north side, shuts off any cold north winds. I want it warm. My blood’s thin. Too long in the tropics. Too much dysentery. Too much malaria. Too much other stuff. Never mind. Don’t need to go into that now. How’d I get talking about stairs? Oh, yes, you asked me.”

He raised his hand and pointed a long, bony finger at Mason. “I told you not to interrupt me. Let me talk.”

Mason smiled. “There are certain things I have to know.”

“All right, I’ll come to them. Wait until I’ve finished, and then ask me for anything I haven’t covered. What was I talking about?”

“Publicity,” Johns Blaine said in the half second of silence which followed Karr’s request.

“Murder,” corrected Gow Loong.

Mason’s eyes shifted to the face of the Chinese, regarding him with keen interest. The one word which he had spoken had been without emphasis, without accent, and without hesitation. It was the one word of prompting which Karr needed.
