“You’re not going to believe this,” the farmer began apologetically, “but ten minutes before you arrived here yesterday I got a phone call. It sounded like a neighbor of mine and he said he was calling to warn me about a crazy man … a real dangerous type … with a beard … that had just been to see him. Said I shouldn’t have anything to do with him. Ten minutes later you showed up. After you left, I called him back. He was out in the fields. Had been all day. His wife had to go get him. He said he hadn’t made that call.”
