"There's another possible theory about the Phillips murder," remarked Mr. Gavin Smeaton. "According to what you know, Mr. Elphinstone, this Meekin is a man who has travelled much abroad—so had Phillips. How do we know that when Meekin and Phillips met that night, Meekin wasn't recognized by Phillips as Meekin—and that Meekin accordingly had a double incentive to kill him?"
"Good!" exclaimed Mr. Lindsey. "Capital theory!—and probably the right one. But," he continued, rising and making for the door, "all the theories in the world won't help us to lay hands on Meekin, and I'm going to see if Murray has made out anything from his search and his questioning."
Murray had made out nothing. There was nothing whatever in the private rooms of the supposed Sir Gilbert Carstairs and his wife to suggest any clue to their whereabouts: the servants could tell nothing of their movements beyond what the police already knew. Sir Gilbert had never been seen by any of them since the morning on which he went into Berwick to hear the case against Carter: Lady Carstairs had not been seen since her departure from the house secretly, two mornings later. Not one of all the many servants, men or women, could tell anything of their master or mistress, nor of any suspicious doings on the part of Hollins during the past two days, except that he had been away from the house a good deal. Whatever share the butler had taken in these recent events, he had played his part skilfully.
So—as it seemed—there was nothing for it but to look further away, the impression of the police being that Meekin had escaped in one direction and his wife in another, and that it had been their plan that Hollins should foregather with them somewhere on the Continent; and presently we all left Hathercleugh House to go back to Berwick. As we crossed the threshold, Mr. Lindsey turned to Mr. Gavin Smeaton with a shrewd smile.
"The next time you step across here, sir, it'll be as Sir Gavin Carstairs!" he said. "And we'll hope that'll not long be delayed!"
"I'm afraid there's a good deal to do before you'll be seeing that, Mr. Lindsey," answered the prospective owner. "We're not out of the wood yet, you know."
We certainly were not out of the wood—so far as I was concerned, those last words might have been prophetic, as, a little later, I was inclined to think Maisie's had been before she went off in the car. The rest of them, Mr. Lindsey and his group, Murray and his, had driven up from Berwick in the first conveyances they could get at that time of night, and they now went off to where they had been waiting in a neighbouring shed. They wanted me to go with them—but I was anxious about my bicycle, a nearly new machine. I had stowed it away as securely as I could under some thick undergrowth on the edge of the woods, but the downpour of rain had been so heavy that I knew it must have soaked through the foliage, and that I should have a nice lot of rust to face, let alone a saturated saddle. So I went away across the park to where I had left it, and the others drove off to Berwick—and so both Mr. Lindsey and myself broke our solemn words to Maisie. For now I was alone—and I certainly did not anticipate more danger.
But not only danger, but the very threatening of death was on me as I went my way. We had stayed some time in Hathercleugh House, and the dawn had broken before we left. The morning came clear and bright after the storm, and the newly-risen sun—it was just four o'clock, and he was nicely above the horizon—was transforming the clustering raindrops on the firs and pines into glistening diamonds as I plunged into the thick of the woods. I had no other thought at that moment but of getting home and changing my clothes before going to Andrew Dunlop's to tell the news—when, as I crossed a narrow cut in the undergrowth, I saw, some distance away, a man's head slowly look out from the trees. I drew back on the instant, watching. Fortunately—or unfortunately—he was not looking in my direction, and did not catch even a momentary glance of me, and when he twisted his neck in my direction I saw that he was the man we had been talking of, and whom I now knew to be Dr. Meekin. And it flashed on me at once that he was hanging about for Hollins—all unconscious that Hollins was lying dead there in the old tower.
So—it was not he who had driven that murderous knife into Hollins's throat!
I watched him—myself securely hidden. He came out of his shelter, crossed the cut, went through the belt of wood which I had just passed, and looked out across the park to the house—all this I saw by cautiously edging through the trees and bushes behind me. He was a good forty yards away from me at that time, but I could see the strained, anxious expression on his face. Things had gone wrong—Hollins and the car had not met him where he had expected them—and he was trying to find out what had happened. And once he made a movement as if he would skirt the coppices and make for the tower, which lay right opposite, but with an open space between it and us—and then he as suddenly drew back, and began to go away among the trees.
I followed him, cautiously. I had always been a bit proud of what I called my woodcraft, having played much at Red Indians as a youngster, and I took care to walk lightly as I stalked him from one brake to another. He went on and on—a long way, right away from Hathercleugh, and in the direction of where Till meets Tweed. And at last he was out of the Hathercleugh grounds, and close to the Till, and in the end he took to a thin belt of trees that ran down the side of the Till, close by the place where Crone's body had been found, and almost opposite the very spot, on the other bank, where I had come across Phillips lying dead; and suddenly I saw what he was after. There, right ahead, was an old boat, tied up to the bank—he was making for it, intending doubtless to put himself across the two rivers, to get the north bank of the Tweed, and so to make for safety in other quarters.
It was there that things went wrong. I was following cautiously, from tree to tree, close to the river-bank, when my foot caught in a trail of ground bramble, and I went headlong into the brushwood. Before I was well on my feet, he had turned and was running back at me, his face white with rage and alarm, and a revolver in his hand. And when he saw who it was, he had the revolver at the full length of his arm, covering me.
"Go back!" he said, stopping and steadying himself.
"No!" said I.
