Adele went flying down the drive, intent only upon one object, to escape from this horrible house. The gates were closed, the lodge was in darkness, and she strove desperately to unfasten the iron catch, but it held.

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 role of interested watcher, and, with a doglike 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.

Spinning round, her shaking pistol raised, she confronted the monster, who was growling and tearing at the clothing in his hand. Again he crouched to spring, and she pressed the trigger. The unexpected loudness of the explosion so startled her that she nearly dropped the pistol. With a howl of anguish he fell, gripping at his wounded shoulder, but rose again immediately. And then he began to move backward, watching her all the time.

What should she do? In her present position he might creep from bush to bush and pounce upon her at any moment. She looked up at the tower. If she could reach the top! And then she remembered the ladder that Jack Knebworth had left behind. But that would have been collected.

She moved stealthily, keeping her eye upon the ape, and though he was motionless, she knew he was watching her. Then, groping in the grass, her fingers touched the light ladder, and she lifted it without difficulty and placed it against the wall. She had heard Jack say that the ape could not have climbed the tower from the outside without assistance, though it had been an easy matter, with the aid of the trees growing against the wall inside, for him to get out.

Bhag was still visible; the dull glow of his eyes was dreadful to see. With a wild run she reached the top of the ladder and began pulling it up after her. Bhag crept nearer and nearer till he came to the foot of the tower, made three ineffectual efforts to scale the wall and failed. She heard his twitter of rage, and guided the ladder to the inside of the tower.

For a long time they sat, looking at one another, the orangutan and the girl. And then Bhag crept away. She followed him as far as her keen eyes could distinguish his ungainly shape, waiting until she was certain he had gone, and then reached for the ladder. The lower rung must have caught in one of the bushes below. She tugged, tugged again, tugged for the third time, and it came away so smoothly that she lost her balance. For a second she was holding the top of the wall with one hand, the ladder with the other; then, half-sliding, half-tumbling, she came down with a run, and picked herself up breathless. She could have laughed at the mishap but for the eerie loneliness of her new surroundings. She tried to erect the ladder again, but in the dark it was impossible to get a firm foundation.

There must be small stones somewhere about, and she began to look out for them. She reached the bottom of the circular depression, and pushing aside a bush to make further progress, feeling all the time with her feet for a suitable prop, suddenly she slipped. She was dropping down a sloping shaft into the depths of the earth!
