G. K. Chesterton: The Wisdom of Father Brown

5. The Mistake of the Machine (continued)

"That's how the whole thing looks supposing this Rian made for Pilgrim's Pond to kill Todd. So it looked to me, till another little discovery woke up what I have of the detective in me. When I had my prisoner safe, I picked up my cane again and strolled down the two or three turns of country road that brought me to one of the side entrances of Todd's grounds, the one nearest to the pool or lake after which the place is named. It was some two hours ago, about seven by this time; the moonlight was more luminous, and I could see the long white streaks of it lying on the mysterious mere with its grey, greasy, half-liquid shores in which they say our fathers used to make witches walk until they sank. I'd forgotten the exact tale; but you know the place I mean; it lies north of Todd's house towards the wilderness, and has two queer wrinkled trees, so dismal that they look more like huge fungoids than decent foliage. As I stood peering at this misty pool, I fancied I saw the faint figure of a man moving from the house towards it, but it was all too dim and distant for one to be certain of the fact, and still less of the details. Besides, my attention was very sharply arrested by something much closer. I crouched behind the fence which ran not more than two hundred yards from one wing of the great mansion, and which was fortunately split in places, as if specially for the application of a cautious eye. A door had opened in the dark bulk of the left wing, and a figure appeared black against the illuminated interior--a muffled figure bending forward, evidently peering out into the night. It closed the door behind it, and I saw it was carrying a lantern, which threw a patch of imperfect light on the dress and figure of the wearer. It seemed to be the figure of a woman, wrapped up in a ragged cloak and evidently disguised to avoid notice; there was something very strange both about the rags and the furtiveness in a person coming out of those rooms lined with gold. She took cautiously the curved garden path which brought her within half a hundred yards of me--, then she stood up for an instant on the terrace of turf that looks towards the slimy lake, and holding her flaming lantern above her head she deliberately swung it three times to and fro as for a signal. As she swung it the second time a flicker of its light fell for a moment on her own face, a face that I knew. She was unnaturally pale, and her head was bundled in her borrowed plebeian shawl; but I am certain it was Etta Todd, the millionaire's daughter.
