“How know you that?”

“Well, being in politics, colonel, I make it my business to know most things that is happening in the county. Now, I’ve been ferreting for some time to get at this post-riding business, and at last I’ve found out how it ’s done. And they ’re going to do it again to-morrow night just this side of Rocky Hill.”

For a moment Brereton was silent. “How is it done?” he asked.

“It’s this way. One of Moody’s gang is working with Squire Hennion as hired man; and when Hennion knows that a rider is due, he drops into the ordinary, and, casual like, finds out all he can as to when he rides on, and by what road. Then he hurries off home and tells his man, and he goes and tells Moody, who gets his men together and does the business.”

“I see. And how can we know where they set the ambush, so as to set a counter one?”

“It’s easy as can be. When they have the mail, it ’s to Hennion’s barn they all goes, where they cut it open and takes out everything as Clinton will pay for, and sends it off at once on one of the boats of provisions as old Hennion is stealing into New York two or three times a week.”

“Ah, that ’s where he’s got the money to buy Greenwood, is it?”

“Yes; I tell you he’s a traitor if there ever was one, colonel. But I guess he’ll be nabbed now. All you’ve got to do is to hide your men in the barn to-morrow night, and you’ll take the whole lot red-handed.”

“And I suppose you tell me this to get your revenge for this afternoon.”

“Just a little, colonel; but don’t forget I’m a patriot, who ’s always trying to serve his country. Now I’ll tell you how we’ll do it. You bring your men down t’ other side of the river to Meegan’s place; and as soon as it ’s dark, I’ll come across the river in a sloop I own and will bring you right over to Hennion’s wharf, from which it will be easy to steal into his barn without no one seeing us.”
