Looking back toward the oblong of light which represented the tower door, she was dimly aware of a figure moving stealthily along the grass that bordered each side of the roadway. For a moment she thought it was Gregory Penne, and then the true explanation of that skulking shape came to her, and she nearly dropped. It was Bhag! She moved as quietly as she could along the side of the wall, creeping from bush to bush, but he had seen her, and came in pursuit, moving slowly, cautiously, as though he was not quite sure that she was legitimate prey. Perhaps there was another gate, she thought, and continued, glancing over her shoulder from time to time, and gripping the little pistol in her hand with such intensity that it was slippery with perspiration before she had gone a hundred yards. Now she left the cover of the wall and came across a meadow, and at first she thought that she had slipped her pursuer. But Bhag seldom went into the open, and presently she saw him again. He was parallel with her, walking under the wall, and showing no sign of hurry. Perhaps, she thought, if she continued, he would drop his pursuit and go off. It might be curiosity that kept him on her trail. But this hope was disappointed. She crossed a stile and followed a path until she realized it was bringing her nearer and nearer to the wall where her watcher was keeping pace with her. As soon as she realized this, she turned abruptly from the path, and found herself walking through dew-laden grasses. She was wet to the knees before she had gone far, but she did not even know this—Bhag had left cover and was following her into the open! She wondered if the grounds were entirely enclosed by a wall, and was relieved when she came to a low fence. Stumbling down a bank on to a road which was evidently the eastern boundary of the property, she ran at full speed, though where the road led she could not guess. Glancing back, she saw, to her horror, that Bhag was following, yet making no attempt to decrease the distance which separated them. And then, far away, she saw the lights of a cottage. They seemed close at hand, but were in reality more than two miles distant. With a sob of thankfulness she turned from the road and ran up a gentle slope, only to discover, to her dismay, when she reached the crest, that the lights seemed as far away as ever. Looking back, she saw Bhag, his green eyes gleaming in the darkness. Where was she? Glancing round, she found an answer. Ahead and to the left was the squat outline of old Griff Tower. And then, for some reason, Bhag dropped his rôle of interested watcher, and, with a dog-like growl, leapt at her. She flew upward toward the tower, her breath coming in sobs, her heart thumping so that she felt every moment she would drop from sheer exhaustion. A hand clutched at her cloak and tore it from her. That gave her a moment’s respite. She must face her enemy, or she herself must perish.
