It was just like Peterson to bluff to the limit of his hand; moreover, it would have appealed to his sense of humour. And the point which was not clear to either Sir Raymond or the German was very clear to him. To them it had seemed an unnecessary complication to bring over the genuine Scheidstrun—but there Drummond could supply the missing link. And that link was his previous acquaintance with the arch-criminal. The combination of shrewd insight and consummate nerve which deliberately banked on that previous acquaintance and turned it to gain was Peterson all over—or rather Blackton, to give him his present name. Moreover, the advantage of having the genuine article at the funeral where he was bound to run into many friends and acquaintances was obvious. Most assuredly the touch of the master-hand was in evidence again, but where was the hand itself? It was that question which Sir Raymond, almost inarticulate with rage, had asked again and again; and it was the answer to that question which Professor Scheidstrun would not or could not give. Listening intently, Drummond had inclined to the latter alternative, though not being able to see the speaker’s face, he had had to rely on inflection of voice. But it had seemed to him as if he was speaking the truth when he absolutely denied any knowledge whatever of Blackton’s whereabouts. An old gentleman with mutton-chop whiskers—that was all he could say. But where he was, or what he was doing, he knew no more than Sir Raymond. He had left that morning with the notes in his possession, and that was all he could tell his infuriated questioner.
And then a sudden silence had fallen while Drummond still craned out of the window listening—a silence which endured so long that finally he stepped back into the room, only to discover that he was locked in. For a moment or two, as has been said, he stood staring at the door; then with a grunt he charged it with his shoulders. But the door was strong, and it took him three minutes before, with a final splintering crash, the door burst open, almost throwing him on his face. For a while he stood listening: the house was silent. And since in ordinary respectable houses the bursting open of a door is not greeted with absolute silence, Drummond’s hand went automatically to his hip-pocket. Past association with Peterson accounted for the involuntary movement, but much water had flowed under the bridge since those happy days, and with a sigh he realised that he was unarmed. With his back to the wall he took careful stock of his surroundings. Every nerve was alert for possible eventualities; his arms, hanging a little forward, were tingling at the prospect of action.
Still there was no sound. The passage was deserted; all the doors were shut. And yet keys do not turn by themselves. Someone had locked him in: the question was, who had done it? And where was he? Or could it be a she? Could it be that monumental woman who had assaulted him only that morning. He turned a little pale at the thought; but with the knowledge that he now possessed of her husband’s complicity in the affair he felt he could meet her on rather more level terms. And there was comfort in the knowledge that everyone in the house was so confoundedly crooked. The likelihood of their sending for the police to eject him from the premises was, to put it mildly, remote.
Silently as a cat, he took a quick step along the passage and flung open the door of the room in which he had left Sir Raymond Blantyre and the German. It was empty; there was no sign of either man. He crossed to one of the heavy curtains which was drawn back in the window behind the desk, and hit it a heavy blow with his fist. But the folds went back unresistingly; there was no one hiding behind it. And then swiftly and methodically he went from room to room, moving with that strange, silent tread which was one of his most marked peculiarities. No one ever heard Drummond coming; in the darkness no one ever saw him, if he didn’t wish him to. The first thing he knew of his presence was a pair of great hands which seemed to materialise out of the night, forcing his head backwards and farther back. And sometimes that was the last thing he knew as well. …
But there was no darkness in the house as he searched it from top to bottom—only silence. Once he thought he heard the sound of a step above him as he stood downstairs in the dining-room, but it was not repeated, and he decided it was only imagination—a board creaking, perhaps. He went into the kitchen and the scullery; the fire was lit in the range, but of cook or servant there was no sign.
And finally, he returned thoughtfully to the hall. There was no doubt about it, the house was empty save for himself. Sir Raymond and the German had gone during the period that he was locked in the room upstairs. And during that period the other occupants of the
