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 glass 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 constituted the sole purpose of the building, and yet it appeared to me that there might have been space 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 assistance 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 encumbered 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.
