"He seemed to lay more stress on the dogs' footprints and the button Lennox picked up than on anything else. Oddly enough, someone else spoke of dogs, now I think of it." And I told him what the chauffeur had said last night. "Queer," said Lessing. "You'd think he'd know a dog when he saw one. I'd like to have a look at that button." "Herrick has it." "He has..." Lessing was silent a moment. "Even if Jakey did kill Aaron, and Aaron is really his brother--hang it all, the thing's so mixed--I don't see that that gets us any further on. Does Lennox think he's at the back of everything? What's he playing at?" "He was at the back of Rebecca's scare, and that business of Freeman. If Freeman were only well enough to speak.... I don't know that he could tell us much then, that we haven't found out for ourselves." "Grant that Jakey did kill his brother, and has succeeded in putting it over. He was at the bottom of all these Dutchman's Hill scares, and that business with Rebecca. Freeman found out something, and he laid for Freeman ... and got him. That doesn't explain the cyclist affair, nor what happened to me." "And it doesn't explain another thing, either," said Mary, breaking in for the first time. "It doesn't explain what the one point was that Lennox himself was unwilling to face, what it was he tried to avoid by ridiculous explanations that wouldn't satisfy a child. I don't mean recently, I mean further back, almost in the beginning, the second time he was here to attend Dick." She turned to her brother. "Perhaps I haven't told you this before. But it did strike me at the time, and afterwards I've been thinking of it more and more. "I was standing out here on the porch, wondering whether I could leave you with Kate and slip over to Lennox's house, or whether I could get hold of anyone to send, when Lennox himself came by, driving. I ran out to stop him and tell him what had happened. He pulled up as soon as he saw me, before I had time to call out, and I tell you if I ever saw a man frightened it was then. He was afraid, and he was afraid before he saw me, or even knew what I had to say. Something had happened, something that gave him a shock, before he came up the road there. He tried to pass it off, but I'm not a fool; I know when a person is just puzzled, and I know when he is afraid, and I tell you that Lennox was afraid. And I'd like to know just what it was that frightened him." "Where was he coming from?" Lessing asked. "Down the road here, the way Austin came just now. He came from the Bend." "From Menning's place." "It might have been. I don't know. He didn't say and I didn't ask him. But something, that morning, had happened to upset him before he got here. And it was as if he knew--or at least expected, what he was going to find." "Did you ask him?"
