"Why should you think to find Miss Dunlop here-in this old ruin?" he argued; and I could see he was genuinely curious. "Come now-straight talk, Moneylaws!-and it'll be all the better for you."

"She's missing since last night," I replied. "It came to me that she likely took a short cut across these grounds, and that in doing so she fell in with Sir Gilbert-or with you-and was kept, lest she should let out what she'd seen. That's the plain truth, Mr. Hollins."

He was keeping his eyes on me just as steadily as he kept the revolver, and I saw from the look in them that he believed me.

"Aye!" he said. "I see you can draw conclusions, if it comes to it.

But-did you keep that idea of yours strictly to yourself, now?"

"Absolutely!" I repeated.

"You didn't mention it to a soul?" he asked searchingly.

"Not to a soul!" said I. "There isn't man, woman, or child knows I'm here."

I thought he might have dropped the muzzle of the revolver at that, but he still kept it in a line with my nose and made no sign of relaxing his vigilance. But, as he was silent for the moment, I let out a question at him.

"It'll do you no harm to tell me the truth, Mr. Hollins," I said. "Do you know anything about Miss Dunlop? Is she safe? You've maybe had a young lady yourself one time or another-you'll understand what I'm feeling about it?"

He nodded solemnly at that and in quite a friendly way.

"Aye!" he answered. "I understand your feelings well enough, Moneylaws-and I'm a man of sentiment, so I'll tell you at once that the la.s.s is safe enough, and there's not as much harm come to her as you could put on a sixpence-so there! But-I'm not sure yet that you're safe yourself," he went on, still eyeing me consideringly. "I'm a soft-hearted man, Moneylaws-or else you wouldn't have your brains in their place at this present minute!"

"There's a mighty lot of chance of my harming you, anyway!" said I, with a laugh that surprised myself. "Not so much as a penknife on me, and you with that thing at my head."

"Aye!-but you've got a tongue in that head," said he. "And you might be using it! But come, now-I'm loth to harm you, and you'd best tell me a bit more. What's the police doing?"

"What police do you mean?" I inquired.

"Here, there, everywhere, anywhere!" he exclaimed. "No quibbles, now!-you'll have had plenty of information."

"They're acting on yours," I retorted. "Searching about Glasgow for Sir Gilbert and Lady Carstairs-you put us on to that, Mr. Hollins."

"I had to," he answered. "Aye, I put Lindsey on to it, to be sure-and he took it all in like it was gospel, and so did all of you! It gained time, do you see, Moneylaws-it had to be done."

"Then-they aren't in Glasgow?" I asked.

He shook his big head solemnly at that, and something like a smile came about the corners of his lips.

"They're not in Glasgow, nor near it," he answered readily, "but where all the police in England-and in Scotland, too, for that matter-'ll find it hard to get speech with them. Out of hand, Moneylaws!-out of hand, d'ye see-for the police!"

He gave a sort of chuckle when he said this, and it emboldened me to come to grips with him-as far as words went.

"Then what harm can I do you, Mr. Hollins?" I asked. "You're not in any danger that I know of."

He looked at me as if wondering whether I wasn't trying a joke on him, and after staring a while he shook his head.

"I'm leaving this part-finally," he answered. "That's Sir Gilbert's brand-new car that's all ready for me down the stairs; and as I say, whether it's storm or no storm, I must be away. And there's just two things I can do, Moneylaws-I can lay you out on the floor here, with your brains running over your face, or I can-trust to your honour!"

We looked at each other for a full minute in silence-our eyes meeting in the queer, bluish light of the electric pocket-lamp which he had set on the table before us. Between us, too, was that revolver-always pointing at me out of its one black eye.

"If it's all the same to you, Mr. Hollins," said I at length, "I'd prefer you to trust to my honour. Whatever quality my brains may have, I'd rather they were used than misused in the way you're suggesting! If it's just this-that you want me to hold my tongue-"

"I'll make a bargain with you," he broke in on me. "You'd be fine and glad to see your sweetheart, Moneylaws, and a.s.sure yourself that she's come to no harm, and is safe and well?"

"Aye! I would that!" I exclaimed. "Give me the chance, Mr. Hollins!"

"Then give me your word that whatever happens, whatever comes, you'll not mention to the police that you've seen me tonight, and that whenever you're questioned you'll know nothing about me!" he said eagerly. "Twelve hours' start-aye, six!-means safety to me, Moneylaws. Will you keep silence?"

"Where's Miss Dunlop?" asked I.

"You can be with her in three minutes," he answered, "if you'll give me your word-and you're a truthful lad, I think-that you'll both bide where you are till morning, and that after that you'll keep your tongue quiet. Will you do that?"

"She's close by?" I demanded.

"Over our heads," he said calmly. "And you've only to say the word-"

"It's said, Mr. Hollins!" I exclaimed. "Go your ways! I'll never breathe a syllable of it to a soul! Neither in six, nor twelve, nor a thousand hours!-your secret's safe enough with me-so long as you keep your word about her-and just now!"

He drew his free hand off the table, still watching me, and still keeping up the revolver, and from a drawer in the table between us pulled out a key and pushed it over.

"There's a door behind you in yon corner," he said. "And you'll find a lantern at its foot-you've matches on you, no doubt. And beyond the door there's another stair that leads up to the turret, and you'll find her there-and safe-and so-go your ways, now, Moneylaws, and I'll go mine!"

He dropped the revolver into a side pocket of his waterproof coat as he spoke, and, pointing me to the door in the corner, turned to that by which he had entered. And as he turned he snapped off the light of his electric lamp, while I myself, having fumbled for a box of matches, struck one and looked around me for this lantern he had mentioned. In its spluttering light I saw his big figure round the corner-then, just as I made for the lantern, the match went out and all was darkness again. As I felt for another match, I heard him pounding the stair-and suddenly there was a sort of scuffle and he cried out loudly once, and there was the sound of a fall, and then of lighter steps hurrying away, and then a heavy, rattling groan. And with my heart in my mouth and fingers trembling so that I could scarcely hold the match, I made shift to light the candle in the lantern, and went fearfully after him. There, in an angle of the stairway, he was lying, with the blood running in dark streams from a gap in his throat; while his hands, which he had instinctively put up to it, were feebly dropping away and relaxing on his broad chest. And as I put the lantern closer to him he looked up at me in a queer, puzzled fashion, and died before my very eyes.

CHAPTER x.x.xV

THE SWAG

I shrank back against the mouldy wall of that old stairway shivering as if I had been suddenly stricken with the ague. I had trembled in every limb before ever I heard the sound of the sudden scuffle, and from a variety of reasons-the relief of having Hollins's revolver withdrawn from my nose; the knowledge that Maisie was close by; the gradual wearing-down of my nerves during a whole day of heart-sickening suspense,-but now the trembling had deepened into utter shaking: I heard my own teeth chattering, and my heart going like a pump, as I stood there, staring at the man's face, over which a grey pallor was quickly spreading itself. And though I knew that he was as dead as ever a man can be, I called to him, and the sound of my own voice frightened me.

"Mr. Hollins!" I cried. "Mr. Hollins!"

And then I was frightened still more, for, as if in answer to my summons, but, of course, because of some muscular contraction following on death, the dead lips slightly parted, and they looked as if they were grinning at me. At that I lost what nerve I had left, and let out a cry, and turned to run back into the room where we had talked. But as I turned there were sounds at the foot of the stair, and the flash of a bull's-eye lamp, and I heard Chisholm's voice down in the gateway below.

"Hullo, up there!" he was demanding. "Is there anybody above?"

It seemed as if I was bursting my chest when I got an answer out to him.

"Oh, man!" I shouted, "come up! There's me here-and there's murder!"

I heard him exclaim in a dismayed and surprised fashion, and mutter some words to somebody that was evidently with him, and then there was heavy tramping below, and presently Chisholm's face appeared round the corner; and as he held his bull's-eye before him, its light fell full on Hollins, and he jumped back a step or two.

"Mercy on us!" he let out. "What's all this? The man's lying dead!"

"Dead enough, Chisholm!" said I, gradually getting the better of my fright. "And murdered, too! But who murdered him, G.o.d knows-I don't! He trapped me in here, not ten minutes ago, and had me at the end of a revolver, and we came to terms, and he left me-and he was no sooner down the stairs here than I heard a bit of a scuffle, and him fall and groan, and I ran out to find-that! And somebody was off and away-have you seen n.o.body outside there?"

"You can't see an inch before your eyes-the night's that black," he answered, bending over the dead man. "We've only just come-round from the house. But whatever were you doing here, yourself?"

"I came to see if I could find any trace of Miss Dunlop in this old part," I answered, "and he told me-just before this happened-she's in the tower above, and safe. And I'll go up there now, Chisholm; for if she's heard aught of all this-"

There was another policeman with him, and they stepped past the body and followed me into the little room and looked round curiously. I left them whispering, and opened the door that Hollins had pointed out. There was a stair there, as he had said, set deep in the thick wall, and I went a long way up it before I came to another door, in which there was a key set in the lock. And in a moment I had it turned, and there was Maisie, and I had her in my arms and was flooding her with questions and holding the light to her face to see if she was safe, all at once.
