The man was sleeping almost on his back, one arm thrown above his head, his chin up, his brown, sinewy throat exposed. That bare throat riveted Jim's vengeful gaze. He knew well that the man, though asleep and at an utter disadvantage, was the most dangerous adversary he could possibly tackle.

Step by step, so lightly, so smoothly, that not a twig crackled under his feet, he crept up, his muzzle outstretched, his fangs gleaming the hair rising along his back. When he was within a couple of paces of his goal, the sleeper stirred slightly, as if about to wake up, or growing conscious of danger. Instantly Jim sprang, and sank his fangs deep, deep, into his enemy's throat.

With a shriek the sleeper awoke, flinging wide his arms and legs convulsively. But the shriek was strangled at its birth, as Jim's implacable teeth crunched closer. The great dog shook his victim as a terrier shakes a rat. There was a choked gurgle, and the threshing arms and legs lay still.

Jim continued his savage shaking till satisfied his foe was quite dead. Then he let go, and turned his attention to Woolly Billy.

The child was sitting up, staring at him with round eyes of question and bewilderment.

"Where am I, Jim?" he demanded. Then he gazed at the transformation in himself—his clothes and his stained hands. He saw his old clothes tossed aside, his curls lying near them in a bright, fluffy heap. He felt his cropped head. And then his brain began to clear. He had a dim memory of the man cutting his hair and changing his clothes.

Upon his first glimpse of the man, lying there dead and covered with blood, he felt a sharp pang of sorrow. He had liked Tony. But the pang passed, as he began to understand. If Jim had killed Tony, Tony must have been bad. It was evident that Tony had carried him off, and that Jim had come to save him. Jim was licking his face now, rapturously, and evidently coaxing him to get up and come away.

He flung his arms around Jim's neck. Then he saw the biscuits. He divided them evenly between himself and Jim, and ate his portion with good appetite. Jim would not touch his share, so Woolly Billy tucked them into his pocket. Then he got up and followed where Jim was trying to lead him, keeping his face averted from the terrible, bleeding thing sprawled there upon the moss. And Jim led him safely home.

When Tug Blackstock, two days later, returned from his visit to Exville, he brought news which explained why a certain gang of criminals had planned to get possession of Woolly Billy. The child had fallen heir to an immense property in England, and an ancient title, and he was to have been held for ransom. From that moment Blackstock never let him out of his sight, until, with a heavy heart, he handed him over to his own people.
