“Mr. Carter, I’ve hearn tell of you that you’re keen and hard when it comes to criminals, but you’re straight with innocent men. I swear——”

“You don’t need to,” interrupted Nick; “you are as innocent as I am, and I know it. I believed it when I started out to see you, but I am going to arrest you for murder, nevertheless.”

“Mr. Carter, I don’t understand! What will my poor wife say?”

“You needn’t let her know. I want you to understand, though. Suspicion has been put on you by an enemy of yours. Now, if I lock you up overnight, it will make this enemy believe that I have finished my work. See?”

“You want to blind him?”

“Yes. Then I can hunt for the real murderer in my own way.”

“All right, Mr. Carter.”

Low was perfectly quiet. He did not talk or act like the hot-tempered man who had threatened Mr. Judson.

“You can tell your wife,” said Nick, “that a man wants you to go to the city on business about the land deal. Let her think that some good luck has come your way. I don’t think you’ll have to disappoint her afterward. Then hitch up your horse, and we’ll go back together.”

Low agreed to this without argument. He went into the house and was gone several minutes. Then he went to the barn and hitched up. A little later, he and the detective were jogging over the road toward Denver.
