Wolfe asked, "Will you have some beer?"

He nodded his head. "Thank you."

I took the hint. In the kitchen I got a couple of bottles from the ice-box and a glass from the shelf and fixed up a tray. I made it snappy because I didn't want to miss anything. I went back with the tray and put it on Wolfe's desk, and then sat down at my desk and pulled some papers out of a drawer and got things fixed up. Manuel Kimball was talking.

"… told me of his visit to your office yesterday. My father and I are on a completely confidential basis. He told me everything you said to him. Why did you say what you did?"

"Well." Wolfe pulled out his drawer to get the opener, removed the cap from a bottle and dropped it into the drawer, and filled a glass. He watched the foam a moment, then turned back to Manuel. "In the first place, Mr. Kimball, you say that your father repeated everything to you that I told him. You can hardly know that. So let us be properly selective. Your tone is minatory. What specifically do you wish to berate me for? What did I say to your father that you would rather I had left unsaid?"

Manuel smiled, and got colder. "Don't try to twist my words, Mr. Wolfe. I am not expressing my preferences, I am asking you to account for statements that seem to me unwarranted. I have that right, as the son of a man who is getting old. I have never before seen my father frightened, but you have frightened him. You told him that Barstow was killed as a result of borrowing my father's golf driver."

"I did, indeed."

"You admit it. I trust that your man there taking this down will include your confession. What you told my father is criminal nonsense. I have never believed the tale of the poisoned needle as regarded Barstow; I believe it less now. What right have you to invent such absurdities and distress, first the whole Barstow family, now my father, with them? Probably it is actionable, my lawyer will know about that. Certainly it is unjustifiable and it must be stopped."

"I don't know." Wolfe appeared to be considering; as for me, I was handing it to Manuel for being cute enough to get what I was doing in the first five minutes; not many had done that. Wolfe downed a glass of beer and wiped his lips. "I really don't know. If it is actionable at all, I suppose it could only be through a complaint of libel from the murdered. I don't suppose you had that in mind?"

"I have only one thing in mind." Manuel's eyes were even smaller. "That it has got to stop."

"But, Mr. Kimball," Wolfe protested. "Give me a chance. You accused me of inventing absurdities. I have invented nothing. The invention, and a most remarkable and original one, even brilliant--and I am careful of words--was another's; only the discovery was mine. If the inventor were to say to me what you have said, I would put him down for a commendably modest man. No, sir, I did not invent that golf driver."

"And no one else did. Where is it?"

"Alas." Wolfe turned a hand palm up. "I have yet to see it."

"What proof is there that it ever existed?"

"The needle that it propelled into Barstow's belly."

"Bah. Why from a golf driver? Why on the first tee?"

"The wasp came from nowhere, and synchronized."

"No good, Mr. Wolfe." Manuel's intent little black eyes were scornful. "It's what I said, criminal nonsense. If you have no better proof than that, I repeat, I have a right to demand that you retract. I do so. I have this morning called on Mr. Anderson, the District Attorney at White Plains. He agrees with me. I demand that you see my father and retract and apologize; likewise the Barstows if you have told them. I have reason to suspect that you have."

Wolfe shook his head slowly from side to side. After a moment he said regretfully, "It's too bad, Mr. Kimball."

"It is. But you caught the crow, now you can eat it."

"No. You misunderstand me. I mean it's too bad that you are dealing with me. I am perhaps the only man on this hemisphere whom your courage and wit cannot defeat, and by incredibly bad luck you find yourself confronted by me. I am sorry; but just as you have assumed a task suitable for your abilities, I have found one congenial for mine. You will forgive me for wheeling onto your flank, since you have made it impossible for me to meet you frontally. I hardly suppose that you expected your direct attack to gain its feigned objective; you could hardly have had so poor an opinion of me as that. Your true objective must have been concealed, and probably it was the discovery of the nature and extent of the evidence I have so far acquired. But surely you know that, for how else could I have foretold the result of the autopsy?--I beg you, let me finish. Yes, I know when and where and by whom the golf driver was made, I know where the man who made it is now, and I know what results to expect from the advertisement which I inserted in this morning's newspapers and which you have perhaps seen."

Not a muscle on Manuel's face had stirred, and no change was perceptible in his tone. His eyes kept straight on Wolfe as he said, "If you know all that--I doubt if you do--is that not information for the District Attorney?"

"Yes. Do you want me to give it to him?"

"I? I want? Of course, if you have it."

"Good." Wolfe wiggled a finger at him. "I'll tell you what you do, Mr. Kimball. Do me a favor. On your way home this afternoon stop at Mr. Anderson's office; tell him what information I have and suggest that he send for it. Now--I am sorry--it is past my lunch hour. May I offer you a compliment? If almost anyone else I have known were in your position I would try to detain him longer on the chance of learning something. With you, I feel that eating my lunch will be more profitable."

Manuel was on his feet. "I should tell you, I am going from here to my lawyer. You will hear from him."

Wolfe nodded. "Certainly your best move. Obvious, but still the best. Your father would wonder if you did not."

Manuel Kimball turned and went. I got up and started after him for the courtesy of the house, but he was out of the front door before I made it.

I went back to Wolfe. He was leaning back with his eyes closed. I asked loud enough to wake him up, "Did that guy come here to find out if he'd have to go ahead and kill his father during the weekend?"

He sighed. His eyes opened and he shook his head. "Lunch, Archie."

"It won't be ready for ten minutes. Fritz only got back at one."

"The anchovies and celery will divert us."

So we went to the dining-room.

Right there, at that point, the Barstow-Kimball case went dead. At least Wolfe went dead, and that was the case as far as I was concerned. It wasn't a relapse, he just closed up. While plenty went into him during lunch, of course nothing came out; and when the meal was finished he went to the office and sat. I sat at my desk and caught up with a few things, but there wasn't much to do, and I kept glancing at Wolfe wondering when he would open up. Although his eyes were closed he must have felt my glances, for all of a sudden he looked at me and said: "Confound it, Archie, cannot paper be made not to rattle?"

I got up. "All right, I'll beat it. But damn it, where? Have you lost your tongue?"

"Anywhere. Go for a walk."

"And return?"

"Any time. It doesn't matter. Dinner."

"Are you waiting for Manuel to bump off his old man?"

"Go, Archie."

It seemed to me that he was rubbing it in, since it was already three-thirty and in another half hour he would himself have left to go up to the plant-rooms. But seeing the mood he was in, I got my hat from the hall and went out.

I went to a movie to think, and the more I thought the more uncomfortable I got. Manuel Kimball's visit and his challenge, for that was what it amounted to, darned near succeeded as far as I was concerned. I had been aware that we weren't quite ready to tell Mrs. Barstow what address to mail the check to, but I hadn't fully realized how awfully empty our bag was. We had found out some things to our own satisfaction, but we had no more proof that there had been a murder than we had had when we started. Let alone who had done it. But that wasn't all; the worst was that there was no place to go from there. Granted that it was Manuel Kimball, how could we tie him up? Find the golf driver. Fat chance. I could see him in his plane flying low over the river or a reservoir, dropping the club out with a chunk of lead wired to the shaft. Trace the poison to him. About the same chance. He had been planning this for years maybe, certainly months; he may even have had the poison with him when he came up with his father from the Argentine; anyway, he could have got it from there at any time--and try and find out. Get him to talk on the telephone with Mrs. Ricci and have her recognize his voice. Sure, that was it; any jury would convict on that without leaving the courtroom.
