"Michael! We need something much better than must have. You did or you didn't. Remember that you are supposed to have told us--"

William Riley butted in: "Hey! Mike, that's why he borrowed old Kimball's driver, because you were off looking for the ball."

"Ah." Wolfe shut his eyes for a tenth of a second and then opened them again. "William, it is unnecessary to shout. Who borrowed Mr. Kimball's driver?"

"Barstow did."

"What makes you think so?"

"I don't think so, I know. I had it out ready to hand to old Kimball, and Barstow's ball rolled off his tee and I fixed it for him, and when I stood up old Kimball was saying to Barstow, 'Use mine,' and Barstow reached out and I handed old Kimball's driver to him."

"And he used it?"

"Sure. He drove right away. Mike didn't come back with the bag until after old Kimball had drove too."

I was having all I could do to stay in my chair. I wanted to do a dance like Spring on the Mountaintop that I'd seen in the movies, and pin a bunch of orchids on William Riley, and throw my arms halfway around Wolfe which was as far as they would go. I was afraid to look at Wolfe for fear I would grin so hard and wide I'd burst my jaw.

He was after the pale skinny kid and the one that wanted to be a good citizen, but neither of them remembered anything about Barstow borrowing the driver. The skinny one said he had his eyes glued far out on the fairway, spotting the place where Manuel Kimball had pulled his drive into the bushes, and the good citizen just didn't remember. Wolfe turned to Chunky Mike. Mike could not say positively that Barstow's driver had been in the bag when he had had it with him hunting the ball, but he could not remember handing it to Barstow, and he could not remember receiving it back and returning it to the bag. During all this William Riley was straining his politeness to keep still. Finally Wolfe got back to him:

"Excuse me, William. Do not think I doubt your memory or your fidelity to truth. Corroboration is always helpful. And it might be thought a little curious that you had forgotten so informing a detail."

The boy protested, "I hadn't forgotten it, I just didn't happen to think of it."

"You mean that you have not included that incident in any of your recitals to your friends?"

"Yes, sir."

"Good, William. I put my question badly, but I see that you have the intelligence to stick to the main clause. Possibly you mentioned the incident to Mr. Anderson?"

The boy shook his head. "I haven't seen Mr. Anderson. The detective came and asked me a few questions, not much."

"I see." Wolfe sighed, deep and long, and pushed the button. "It is tea time, messieurs."

Of course for Wolfe that meant beer. I got up and collected the boys and herded them into the kitchen; sure enough, the watermelon was intact. I cut it into four quarters and passed it around. Fritz, having been to answer Wolfe's bell, was arranging a glass and two bottles on a tray; but as he went down the hall I noticed that he turned toward the stairs instead of the office. I glanced at my wrist. It was two minutes to four. The son-of-a-gun had saved his schedule! I left the boys with the melon and hurried out and caught him on his way to the elevator. He said: "Give the boys my thanks, pay them adequately but not generously, for I am not a generous man, and take them home. Before you leave, telephone the office of E.D. Kimball and learn when he is expected to return from Chicago. He is probably still alive, since he had either the shrewdness or the luck to remove himself a thousand miles from his destiny. If by any chance he has returned get him here at once; on that there must be no delay."

"Yes, sir. And don't you think that if this news got to Mr. Anderson it would only confuse and upset him? Hadn't I better try to persuade the boys to keep it in the family?"

"No, Archie. It is always wiser, where there is a choice, to trust to inertia. It is the greatest force in the world."

When I got back to the kitchen Fritz was cutting an apple pie.

After I had finished delivering the caddies here and there all over Westechester, I certainly would have loved to run over to Kimball's place and say to Manuel, "Would you mind telling me whether your father keeps his golf bag in his locker at the club and whether you have a key to it?" I had an idea he would recognize that as a question that couldn't be answered just by lifting his eyebrows. I already had him down for two thousand volts. But I realized that if it was him we had a big advantage in his ignorance of what we had found out, and I also realized that if I expected Manuel Kimball to be arrested and convicted of murder there would have to be a little more evidence than the fact that he made me nervous.

I had another temptation, to stop in at Anderson's office and offer to bet him ten thousand dollars that nobody had murdered Peter Oliver Barstow. Wolfe had certainly started a game of hide-and-seek. For two days he and I had been the only two people alive, except the man that did it, who knew that Barstow had been murdered; now we were the only two, with the same exception and the caddies, who knew that he had been killed by accident.

I did go to the Green Meadow Club, after getting the last caddy delivered; it was close by. I went intending to go into the locker question a little, but after I arrived I got cold feet. It might ruin everything if it became known that we had the faintest interest in lockers, since it was common knowledge that Barstow's bag had never been in his. So I just had a little talk with the caddy master and said hello to the chief steward. Maybe I was hoping to get another eyeful of Manuel Kimball, but I didn't see him anywhere.

E.D. Kimball, as his son had told me, had a grain brokerage office on Pearl Street. When I had telephoned there a little after four o'clock I had been told that Kimball was expected back from Chicago the next day, Friday, on the Century. If it hadn't been for that I think I would have tried to start something there in Westchester that evening, if it had been nothing more than to wait till dark and sneak over to the Kimball place and peek in at the windows; but with Kimball on the way there was nothing to do but wait. I went on home.

After dinner that evening Wolfe had me take my notebook and read to him again about my visit to Manuel Kimball, also everything that Sarah and Larry Barstow had said about him, though that wasn't much. We had a general discussion and got our minds to fit; we even considered the possibility that the lending of the driver had been planned and that old Kimball had murdered Barstow, but of course that was out, that was nothing but drivel. I took a few cracks at Manuel, but when Wolfe put it up to me seriously I had to say that not only was there no evidence against Manuel, there wasn't even any reason to suspect him. As far as I knew, it was no more likely to be him than any other member of the Green Meadow Club who had had opportunity to get at the Kimball locker.

"All the same," I insisted, "if he was my son I'd send him on a trip around the world and build a fence across the Pacific Ocean so he couldn't get through."

Before we went to bed Wolfe outlined again my program for the following day. I didn't care much for the first number on it, but of course he was right; the caddies were sure to talk, and the talk would get to Anderson, and it wouldn't hurt us any to get there first since the information was certain to reach him anyhow. I could perform that errand of mercy and still get to Kimball's office almost as soon as he arrived from Grand Central.

So early the next morning found me in the roadster bound for White Plains again. I was hoping the same motor cop would trip me up, it would have been so neat, since I could have handed him the same yarn as the day before and maybe this time have had the pleasure of an escort to the courthouse. But I made it from Woodlawn to the Main Street bridge without seeing anything more exciting than a squirrel running up a tree.
