“Of course people do lean out of the window when the train stops and there isn’t a station there. But you can’t be certain that your man will look out: and people generally look out in the direction in which the train is curving: they can see more that way. And you could only make him look out—steady on! Keep steady, Reeves! Oh yes, you could certainly do that: thank you very much indeed; the whole thing becomes a good deal clearer. And then you hit him a good smack on the head, that stuns him anyhow, with a stick. That must have made you rather noticeable, because people don’t take sticks up to London much—strong sticks, I mean. It would have to be—well, I’m blessed!” And in another moment Reeves was scrambling down the bank, precipitous as it was, to a clump of rank grass some ten feet below. Half-hidden in this he had seen, and now painfully secured, a large knotted stick such as may be carried by a peaceable man, but undoubtedly would come in useful in a scrap. It might be coincidence of course, but that seemed too good to be true. And yet, was it not also too good to be true that he, nearly a week after the event, should be holding between his hands the very weapon, undiscovered hitherto, which had begun the assault? There was no name on it. There was no blood on it, nor any mark of violence. And yet it could undoubtedly have given a stunning blow without breaking or showing signs of the contact. The next point was to get his treasure home, and this was not so easy as it sounds. He did not dare to carry it openly with him to the dormy-house; if the murderer really lived there he might easily catch sight of the stick and take the alarm. To carry a stick up your trousers-leg makes you a marked man at once. He left it concealed in the bushes a little way from the dormy-house, and went to fetch his golf-bag, in which he bestowed it upside down, and so smuggled it unobserved to his room. Gordon and Carmichael were properly thrilled by the discovery, but were not very helpful in making suggestions for its use. Carmichael said that he might take the stick to Brotherhood’s grave and see if it bled there, but added that this test was no longer used, he believed, in the detective world. On the whole, it seemed best to hide it away, taking no risks with stray visitors, and keep it until suspicion was thrown on some definite person—then it might come in handy. Meanwhile, Reeves thought he had now sufficient grounds for optimism about his case to justify him in a Sunday afternoon call on Miss Rendall-Smith. This time, Gordon refused to accompany him, and he went over in his own car, though he was careful to garage it at the hotel, for fear the sight of it might have painful memories for his hostess. There was no mistaking the eagerness and anxiety of the tone in which she asked for news. Reeves, with an indiscretion which he would have been the first to criticize a week ago, told her all his suspicions and all his hopes.
