Her heart leaped joyfully as she turned in at the drive gates of her home and felt the well-remembered gravel crunching under her feet. The silhouette of the ruined castle against the summer sky gave her the feeling which all returning wanderers know. And, when she stepped on to the lawn and looked at the black bulk of the house, indistinct and shadowy with its backing of trees, tears came into her eyes. She experienced a rush of emotion which made her feel quite faint, and which lasted until, on tiptoeing nearer to the house in order to gloat more adequately upon it, she perceived that the French windows of the drawing-room were standing ajar. Sam had left them like this in order to facilitate departure, if a hurried departure should by any mischance be rendered necessary, and drawn curtains had kept the household from noticing the fact. All the proprietor in Mrs. Hignett was roused. This, she felt indignantly, was the sort of thing she had been afraid would happen the moment her back was turned. Evidently laxity--one might almost say anarchy--had set in directly she had removed the eye of authority. She marched to the window and pushed it open. She had now completely abandoned her kindly scheme of refraining from rousing the sleeping house and spending the night at the inn. She stepped into the drawing-room with the single-minded purpose of rousing Eustace out of his sleep and giving him a good talking to for having failed to maintain her own standard of efficiency among the domestic staff. If there was one thing on which Mrs. Horace Hignett had always insisted it was that every window in the house must be closed at lights-out. She pushed the curtains apart with a rattle and, at the same moment, from the direction of the door there came a low but distinct gasp which made her resolute heart jump and flutter. It was too dark to see anything distinctly, but, in the instant before it turned and fled, she caught sight of a shadowy male figure, and knew that her worst fears had been realised. The figure was too tall to be Eustace, and Eustace, she knew, was the only man in the house. Male figures, therefore, that went flitting about Windles, must be the figures of burglars. Mrs. Hignett, bold woman though she was, stood for an instant spellbound, and for one moment of not unpardonable panic, tried to tell herself that she had been mistaken. Almost immediately, however, there came from the direction of the hall a dull chunky sound as though something soft had been kicked, followed by a low gurgle and the noise of staggering feet. Unless he was dancing a _pas seul_ out of sheer lightness of heart, the nocturnal visitor must have tripped over something.
