“How much money?” asked Tom Halstead, bluntly.

“Can you guess how much there is here?” inquired Rexford. He took from one of his pockets and held out a small, compact roll of bills. Tom coolly struck another match, scanning the roll, and discovering that there was a twenty-dollar bill on the outside of it.

“There’s five hundred in this little pile,” observed Mr. Rexford. “Half a thousand dollars. That’s just the starter, you understand. If you obey certain orders you’ll get another little lump of money like this. In the end there’ll be a sum big enough for you to live on the rest of your days. Like the sound of it? And this half thousand goes to you at once, in return for a promise or two. Now, can we undertake business together?”

Though Captain Tom Halstead’s eyes had momentarily glistened at the tempting sight of so much money, he now asked, composedly:

“What’s the business?”

“You’re skipper of Francis Delavan’s ‘Rocket,’ aren’t you?”

“Yes.”

“You expect to continue to hold the position?”

“Probably all through this summer.”

“Then see here, Captain Halstead, all you have to do is to follow certain orders. One of them, for instance, is, whenever you see another craft near that hoists a red pennant, crossed diagonally by a single white stripe, you’re to have something happen to your boat so that you can’t proceed for some time. You can make believe something happens to the boat, you know.”
