To a mournful dirge on the pipes, Ashiel was laid in his rocky grave, and the throng of black-garmented people was ferried back the way it had come. Gimblet, wrapped to the ears in a thick overcoat, and with a silk scarf wound high round his neck, shivered in the cold air, for the wind had veered to the north, and the first breath of the Arctic winter was already carried on it. The waters of the loch had turned a slaty black; little angry waves broke incessantly over its surface; and inky black clouds were gathering slowly on the distant horizon. It looked as if the fine weather were at an end; as if Nature herself were mourning angrily at the wanton destruction of her child. The pity and regret Gimblet had felt, as he stood by the murdered man's grave, suddenly turned to a feeling of rage, both with himself and with the victim of the crime. Why in the world had he not managed to guard against a danger of whose imminence he had had full warning? And why in the name of everything that was imbecile had Lord Ashiel, who knew much better than anyone else how real the danger was, chosen to sit at a lighted window, and offer so tempting a target to his enemy? Suddenly, in the midst of his musings, a sound fell on the detective's ear; a voice he had heard before, low and musical, and curiously resonant. He looked in the direction from which it came and saw two people standing together, a little apart, in the crowd of those waiting at the water's edge for a craft to carry them ashore. There were only two or three boats; and, though the ghillies bent to their oars with a will, every one could not cross the narrow channel which divided the island from the mainland at one and the same time. A group had already formed on the beach of those who were not the first to get away, and among these were the two figures that had attracted Gimblet's attention. They were two ladies, who stood watching the boats, which had landed their passengers and were now returning empty. The nearest to him, a tall woman of ample proportions, was visibly affected by the ceremony she had just witnessed, and dabbed from time to time at her eyes with a handkerchief. But it was her companion who interested him. She was short and slender; her slightness accentuated by the long dress of black cloth and the small plain hat of the same colour which she wore. A thick black veil hung down over her face and obscured it from his view, but about her general appearance there was something strangely familiar. In a moment Gimblet knew what it was, and where he had seen her before. He had caught sight, in her hand, of a little bag of striped black satin with purple pansies embroidered at intervals upon it. Just such a bag had lain upon the table of his flat in Whitehall a few weeks ago, on the day when its owner had stolen the envelope entrusted to him by Lord Ashiel. "It is she," breathed the detective, "the widow!"
