the first deliberate lie. The others had all been evasions.

“But it has to be within those two days? Friday or Saturday?”

That’s right I made a deposit Friday morning.”

“There’s no chance it could have been left over in the register or in the safe from previous receipts? I mean, as change, or an oversight, or something like that?”

“I don’t think so,” I said. “We leave change, sure; but nothing larger than tens.”

“How about this morning? Before the bank opened?”

I shook my head. “No-o.”

Otis. Otis had come in while I was taking Mrs. Nunn’s payment out of the register. He would know those motors had been picked up. And also that the charges had been over twenty dollars. Careful, pal. Careful.

“Well, we’ve got something to start with, anyway,” Ramsey said. “We’ve isolated it to two days’ receipts. Now—what is your approximate volume of business?”

“About forty thousand last year.”

“That breaks down to around—hmmmmm—,” he said, frowning. “Say between a hundred and hundred-and-fifty a day.”

I didn’t say anything; I merely nodded. That was an over-simplification, and it was badly booby-trapped. But if he didn’t see it I wasn’t going to tell him.

He went on. “But along with tackle you sell boats and motors. Items of two hundred to a thousand and more. So a lot of your business must be in large individual sales, paid by check.”

It was no wonder criminals didn’t like to tangle with them, I thought. Still, there was a certain pleasure in watching an incisive and well-honed mind at work, even if you were watching it from the other side of the fence.

“That’s right,” I said. “But on the other hand, in the course of a day we sell a hell of a lot of small items. Flies, leaders, plugs, lines, spinning lures, and so on. We make change for a lot of twenties.”

He nodded. “Most of your business is local? That is, with people you know, at least by sight?”

“A good part of it, yes. Say within a fifty-mile radius. But fishermen can come from anywhere. We even get a lot of trade from Sanport.”

I was still thinking about Otis. I had to find out, before I went too far with this.

“It’s just possible the shop man may know something about it,” I said. He covers the front when I’m out.”

“I was just coming to that,” Ramsey said. “Is he here now?”

“Yes,” I said. “Just a moment.”

I went out in the showroom and called him. He came in a moment later, wiping his hands on a piece of waste, which he shoved in the pocket of his overalls.

I performed the introductions, and let Ramsey take it from there. Otis looked at the note, frowning, and then shook his head.

“No,” he said. “I don’t place it.”

I sat down and lit another cigarette.

“It came from here,” I said. “There’s not much doubt of that; it was in that bank deposit this morning. You were here when I was making it up—remember, you came in while I was putting the change in the register. Do you recall seeing it while I was doing all that?”

“I don’t think so,” he said. “But, hell, you could look right at it and not see it. It’s just another twenty-dollar bill. I could have taken it in myself.”

He hadn’t noticed. I was shuffling money and he was making sardonic wisecracks about it, but that was as far as it went. He didn’t know I’d taken two twenties out of the register while putting the change in.

He went back to the shop.

I sighed and spread my hands. “Otis just about named it,” I said. “You look at money, but you never see it. Nothing but the figures in the corners.”

He nodded. “I’d appreciate it if you’d keep trying, though. There are a number of angles in a thing of this sort. If the man comes back, for instance, you may remember waiting on him Friday or Saturday. When you sell a particular piece of merchandise, try to remember the last time you sold the same thing and how it was paid for.”

“Okay,” I said. “Now, what about if another one shows up? You want me to call the bank? Or you?”

“Call our office in Sanport. We would appreciate it.”

“Any new twenty?” I asked. “Or does it have to have that mark?”

“The mark is not significant,” he said thoughtfully. “Though it may have it. The things to watch for are the year, and then the number.”

“Is it all right if I write this one down?”

“Yes.”

I pulled over a
