“Because,” he was telling me, “this is a private matter. You see, I recognized you, Mr. Goodwin. Your face is not as well known as your employer’s, but it has been in the papers on several occasions, and you were in my mind on account of the news. The radio bulletins have included the detail that Nero Wolfe and his assistant were present and engaged by Mr. Chisholm. So when I saw you with my niece I recognized you and realized we should talk privately. But you’re an impulsive young man, and for fear you may not like what I say, I make conditions. I shall stay here near the door. You will move to that packing case back of you and sit on it, with your hands in sight and making no unnecessary movements. My niece will put the chair here in front of me and sit on it, facing you, between you and me. That way I will feel free to talk.”

I thought he was batty. As a setup against one of my impulses, including a gun if I had had one, it made no sense at all. I backed up to the packing case and lowered myself, resting my hands on my knees to humor him. When Lila saw me complying she moved the chair, the only one there, as directed, and sat with her back to him. He, it appeared, was going to make a phone call. He did touch the phone, which was on a narrow counter at his right under the shelves of bottles, but only to push it aside. Then he picked up a large bottle of colorless liquid, removed the glass stopper, held it to his nose, and sniffed.

“I do not have fainting spells,” he said apologetically, “but at the moment I am a little unstrung. Seeing my niece here with you was a real shock for me. I came back here to consider what it might mean, but reached no conclusion. Perhaps you’ll explain?”

“Your niece will. Tell him, Lila.”

She started to twist around in the chair, but he commanded her, “No, my dear, stay as you were. Face Mr. Goodwin.” He took another sniff at the bottle, keeping it in his hand.

She obeyed. “It’s Bill,” she said. “They’re going to arrest him for murder, and they mustn’t. They won’t, if we tell them how you offered to pay him for fixing the game and he wouldn’t do it. He won’t tell them on account of me, so we have to. I know I promised you I wouldn’t, but now I’ve got to. You see how it is, Uncle Dan, I’ve got to. I told Mr. Goodwin, to get him to come along. The best way—”

“You haven’t told the police, Lila dear?”

“No. I thought the best way was to come and get you to go with me, and I was afraid to come alone, because I know how bad it will be for you — but it will be worse for Bill if we don’t. Don’t you see, Uncle—”

“Keep your back turned, Lila. I insist on it. That’s right, stay that way.” He had been talking in an even low tone, but now it became thin and strained, as though his throat had tightened. “I’ll tell why I want your back to me, so I can’t see your face. Remember, Goodwin, don’t move. This is a bottle of pure sulphuric acid. I was smelling it just to explain why I had it; of course it has no smell. I suppose you know what it will do. This bottle is nearly full, and I’m holding it carefully, because one drop on your skin will scar you for life. That’s why I want your back to me, Lila. I’m very fond of you — sit still! And I don’t want to see your face if I have to use this acid. If you move, Lila dear, I’ll use it. Or you, Goodwin — especially you. I hope you both understand?”

Lila was stiff, white, pop-eyed, gazing at me. I may have been stiff too; anyhow, I didn’t move. His hand holding the bottle was raised, hovering six inches above her head. She looked as if she might keel over, and I urged her, “Sit tight, Lila, and for God’s sake don’t scream.”
