A little short of the House by the Lock I stopped him. A certain instinct seemed to bid me not be too ostentatious in the manner of announcing my arrival. I got out, and by the light of a round, red moon rising over black trees in the east I glanced at my watch. It was five-and-twenty past nine. The whole day, since my arrival at Southampton in the morning, had gone in searching for Karine, and it might be that I was as far from success now as I had been in the beginning.

A hundred yards away a small yellow light shone steadily through the moon-tinged darkness. I thought it came from the House by the Lock, though the one poor ray made but scant cheer of illumination for a bride's homecoming.

"Wait here for me," I said to the driver. "I may come within half an hour, I may be much longer; but, at all events, wait. Here is a sovereign for you, and you shall have as much again when I return."

The tone of his voice told me that he was suspicious, as well as curious, regarding the mysterious intentions of his fare; but I was sure that he would not fail me. Two pounds were not to be so easily picked up every evening.

I walked on rapidly. As I approached the House by the Lock I lost sight of the yellow gleam which for some time had guided me, but the moon glinted bleakly on the staring panes of dark, upper windows.

Desolate as the place had appeared at the hour of sunset, it had had an air of hospitable welcome at that time compared to that which it wore now. Never, it seemed to me, had I seen a habitation so grim, so silently suggestive of haunting, evil things. The face of the moon, as it rose, lost the ruddy hue which had coloured it nearer the horizon, and its paling disc was swept by black and ragged storm clouds. The wind moaned through the trees like the wail of a lost soul, and there was a stealthy, monotonous lapping of the dark waters so close at hand.

Other sound there was none, and, though I had seen the small ray from a distance, now--so far as I could ascertain--not a window in the whole gloomy pile was lighted.

I went up the path, knocked, and rang the bell, which sent back jangling echoes, such as belong in one's fancy to an uninhabited house. From a distant kennel a dog began to bay. Otherwise I was not answered, and as I rang and thundered on the knocker again, the animal's voice at length subsided into a protesting whine.

I ought by this time to have been sure that Wildred and Karine were not in the house, but, on the contrary, I was by no means certain of that fact. Mentally I argued that, if the master was absent, a caretaker or servant would certainly have been left, and unless a stone-deaf person had been selected for the post my violent alarms would have brought him to me.

If any reason existed, however, why the door should not be opened, it would be easy to understand how and why the caretaker might be suddenly afflicted with an inability to hear.

Instead of being plunged into discouragement, an ever-kindling fire of rage mounted within me. Rather than go away ignorant as to whether Karine was hidden in this hateful house or not, I would force an entrance. I sprang down the steps and went to one of the bow windows nearest the door.

Not an instant's hesitation had I in kicking in one of the panes of gla.s.s, but, as it happened, I had only my trouble for my pains. There were solidly-barred shutters inside, so heavy that even I, strong man as I was, could not break them open.

Furious now, I ran up to the door again, and drove my gloved fist through the gla.s.s in one of the curious, six-inch-wide window panes that ran the length of the door on either side. The shivered gla.s.s jingled sharply on the polished wood of the floor inside, and I thrust in my arm up to the elbow, hoping to get at the lock on the door within. As I did so footsteps came running in the distance.

"Here! Here! What's the matter with you?" cried an imperative voice.

I had heard it before, I remembered. It was that of the eminently respectable-looking servant who had so cleverly defended his master's reputation on the occasion of my former visit to the House by the Lock.

"If you're a burglar," remarked the voice, "you'd better go away while you can. I have a revolver, and my hand is on the trigger now."

"I am no burglar," I returned. "This is not exactly the time of night to expect such gentry, is it? But you've kept me waiting long enough. I wish to see your master and mistress, whom I happen to know are here this evening, and I don't mean to go away without doing it."

The man inside chuckled.

"Nice way of announcing yourself, ain't it, sir? But as it happens you'll have to go elsewhere to see my master and the new mistress. I don't know where they are--it ain't likely I should--but I _do_ know they aren't in _this_ house, where there isn't a solitary soul but me. As for the time of night, that's neither here nor there, so long as I'd chosen to go to bed; and I can't dress all of a minute to please anybody that likes to come banging at the door. You deserve to be had up for damaging the house, that you do, whoever you may be."

There was a ring of virtuous indignation in the voice, and for a few seconds' length I hesitated. Perhaps, after all, the fellow was telling the truth. I was very certain of his capacity for lying, but it might well be that Wildred and Karine had not really come here. Still----

Far away a door slammed sharply, and just in time to decide me. The man _had_ lied. He had just told me that he was alone in the house, and this one sound had unmistakably proved the falsehood. It was not the sort of noise with which the wind shuts a door, even had the wind been violent enough to do so, and windows open to admit it. The latch had been lifted by a human hand.

The servant, who was entirely out of my sight, began talking hurriedly, jabbering any nonsense, as though to cover what had happened. I listened intently, and through his chattering I fancied that I could hear--subdued with distance and intervening walls--the sound of a woman's crying.

My heart seemed to leap into my throat. I could feel the blood throbbing almost to bursting at my temples.

"You liar!" I roughly exclaimed. "They _are_ here, and I will see them, if I have to break the door down!"

"Try it, then!" the man cried, tauntingly. "Just try it--and you may try all night. Ta, ta! Good-bye, and good luck to you!"

I heard his feet tapping swiftly along the uncovered floor as he ran away. Another door was opened and closed, and he was out of earshot.

Desperately I again endeavoured to find the lock. It was no use. Thrust in my arm as far as I might I could not touch it, and though I broke the narrow pane on the other side as well, the fastenings of the door were beyond my reach.

With all my strength I flung myself against the door, but the heavy wood stood firm as though it had been a sheet of iron. There was evidently no hope in that direction, and dizzy with my own rage and desperation, I began attempting some of the windows. But all were secured with the impregnable shutters and bars inside, and it would have seemed that the inmates of the House by the Lock were prepared to stand a siege.

Whether it was Karine whom I believed I had heard weeping or not, I could not be sure. I could not even have taken my oath that there had been such a sound at all, but I was morally certain of it.

I ran round the house, trying in vain to batter in another door, and was met everywhere by silence and darkness. At the side, however, I came at last upon the extension with the tower, whence I had seen the suspicious smoke and flame pouring on that memorable Christmas afternoon. Over the roof of the low "studio," which possessed no windows, I could see a faint yellow glow, like a luminous halo or crown, and suddenly, as I stood regarding it in some bewilderment, I recollected the skylight which I had observed from within.

If I could in some way climb to the top, break through the gla.s.s and let myself down, the problem as to how I should get into the house would be effectually solved.

It now struck me that the studio, as seen from outside, was disproportionately large compared with the room inside, as I remembered it. There had been only the one, which apparently const.i.tuted the sole purpose of the building, and yet it appeared to me that there might have been s.p.a.ce for two of the same small size.

Low as the erection was it was too high for me to climb, and I began hastily looking about for some means of a.s.sistance in carrying out my plan.

In the coach-house, I thought, there might be a ladder, and thither I repaired without delay. But the doors were padlocked, and try them as I might I could not open them.

What was I to do? The more difficulties which enc.u.mbered my path, the more did I determine to surmount them. Returning towards the house I noticed a large rustic seat placed under an ancient apple tree, and it occurred to me that if I could balance the article against the projection of the building I might, by standing it on end, use it as an improvised ladder. If I could only mount for a certain distance I could pull myself up by the ledge of stonework which ran along the edge of the flat roof.

The light which apparently filtered through the skylight had warned me to be cautious in my movements. Whoever was in the house must have known long ago that someone was determined upon forcing an entrance, but, judging by the laughing taunts of the servant, it would be believed that the boast had been a vain one.

If anyone was in the studio it might be as well if, for a few moments at least, I could see without being seen or heard. I therefore went about my preparations as quietly as possible.

I dragged the rustic seat across the gra.s.s and set it in an angle between the tower and the low building of the studio, giving it a certain slanting inclination, that it might not fall when burdened with my weight. Then I scrambled up, not venturing to pause for an instant at the top, for I could feel that the thing was slowly beginning to slide from under me.

With a leap I caught the ledge of stone that ran round the roof, and setting my knee against the wall, helped myself up. It may read simply enough when written down in black and white, but it was rather a difficult task in the accomplishment, and I felt that I had reason to congratulate myself on my own success when it was done.

Framed in a margin of dark roof eight to ten feet in width was the skylight, through which penetrated a subdued radiance.

Cautiously, noiselessly, I crawled to the round bubble of gla.s.s and looked down. A curtain of embroidered Indian silk was drawn half across, but through the open s.p.a.ce that was left I could see something of the interior.

The jewelled lamp which I had previously observed hanging from the centre alone illumined the octagonal room. Now that I was on the roof I was able to appreciate more than ever the smallness of the studio. There was s.p.a.ce for a wide pa.s.sage running all the way round, between the inner walls and the outer walls. I suspected method in this design--a secret which Wildred had cleverly contrived to hide, and which, in conjunction with the mystery of the tower, might account for much that had been dark before.

As I looked a figure pa.s.sed into my line of vision. It was Wildred walking restlessly up and down with his hands behind him. I could hear the murmur of his voice, though through the gla.s.s of the skylight the words were not distinguishable.

Suddenly there came a sharp exclamation in a woman's voice, and my heart gave a responsive bound. Wildred was talking to Karine, and it was she who had answered him with a cry.

I had not expected, when I decided upon trying to enter like a burglar through the skylight, that Karine would be in the studio. It would doubtless frighten her very much if I should suddenly make my appearance beside her amid a shower of broken gla.s.s, and I hesitated so to alarm her, unless the man down there was already commencing to use his power to torment her. If she would only go out and leave me to give Wildred a surprise I would have been thankful; but as I could not hope for her to do that, I determined to know what her companion was saying to her, which had caused her to exclaim in astonishment or perhaps in fear.

I took out my pocket-knife, and with great care to avoid all noise I began to loosen one of the small diamond-shaped panes from its leaden setting. As soon as it was released at one end I slipped the point of the knife underneath and so raised it that there might be no danger of its falling downward and startling those within the room.
