Buck was never a heavy sleeper; his boyhood had been too bedless for him to attach much importance to sleep now. Too often had the tip of a policeman's boot stirred him gently, as he lay curled up near an alley-way in London. Too often had rude kicks awakened him, when down in the "slums" he huddled, numb with cold and hunger. His ears had grown acute, his legs nimble in that dreadful, faraway life, and listening while he slept became second nature. Thus he sat bolt upright in his comfortable little bed above the carriage house when a soft creeping footstep stole up the gravel walk from the stables to the kitchen. The night was very warm, and the open window at his elbow was shutterless. In the dark he could see nothing at first, then he made out the figure of a man, crouching low, and creeping around the kitchen porch to the doctor's surgery window. Immediately afterwards a low, gentle, rasping sound fell on his ears. He had seen enough of crime in the old days to know the man was filing something. Should he awaken Watkins? What was the use? Watkins would probably jump up, exclaiming aloud. He always did when awakened suddenly. Perhaps, after all, he could alarm the family before the man got in. Then, to his amazement, someone opened the window from the inside. By this time Buck had got his "night-sight." The man inside was exactly like the man outside, and he had evidently effected an entrance into the house some time during the day when the maids were upstairs, and had probably concealed himself in the cellar. Both wore masks. Instantly Buck was out of bed, dragging on his trousers. Then, barefooted and shirtless, he slipped downstairs, slid the side door open enough to squeeze through, and peered out. All he could see was the last leg of a man disappearing through the window. They were both inside now. Buck knew every room, hall and door in that house, for every spring and fall he had helped the maids "clean house," taking up and laying carpets. The knowledge stood him in good stead now. What window upstairs would be open, he wondered. The bath-room, of course; it was small, but he could wriggle through it, he told himself, or he would break every bone in his body, at least, trying. All this time he was running and crouching along the shadow of the high stone wall, that, bordered with shrubs, made splendid "cover." He reached the kitchen, and, without waiting to think whether it would bear him or not, seized hold of the twisted vine trunks of the old Virginia creeper that partly covered the house from ground to roof. Fortunately they held, and up he went like a young squirrel, his bare toes clutching like claws in the tangle of the stems and twigs. He gained the roof, crawled rapidly along, and reached the bath-room window, only to find he could barely clutch the sill with the tips of his fingers. Standing on tiptoe, he got a little grip, then his bare toes and knees started to work; inch by inch up they went over the rough stone wall, while his hands slipped further and further over the sill, until they could seize the ledge on the inside. Twice his knees slid back, then his toes refused to clutch. They grew wet, and warm, and he knew the sickening slipping back was because of blood oozing from his skin. But he was in the bath-room now, and didn't care. Then, as he flung the door open, the whole downstairs hall was flooded with light, and a strange choking sound came from below. Then the doctor's voice, smothered but audible, begging, "Go back! Go back, Connie! Lock your door!"
"You say one word aloud and I'll fire!" said a low voice, and Buck reached the head of the stairs only to see Doctor Raymond lying half dressed on the floor, his hands tied behind him, and a grasp of strong, dirty fingers on his throat.
"Oh, you're killing him! You're killing my father!" cried Miss Connie, in a half scream, as, too frightened to move, she stood huddled back in a corner, gripping a large cloak about her.
Buck stared at the scene a fraction of a second. He could understand it all. The doctor had been alarmed and had gone downstairs to investigate. Miss Connie had been awakened and had followed her father, thinking probably that he was ill. All this flashed through the boy's mind as he flung out his weaponless hands in despair, but the gesture was the salvation of the household. His fingers touched something cold, hard, polished. It was a huge, heavy, brass bowl that held a fern. How often his strong young fingers had cleaned that bowl with powder and chamois skin, with never a thought that it would serve him well some time! Now he grasped it, and creeping noiselessly around the large, square "balcony" of the upstairs hall, he stood directly above the ruffian whose fingers yet clutched the doctor's throat.
"Catch that girl!" the other man was saying. "She'll scream! Catch her,
I say, and gag her!"
"Oh, my girl, my little girl! Leave her alone, you demons!" gasped the helpless doctor. But just as the fingers loosed their brutal grasp on the father's throat to reach for the frail, delicate flesh of the daughter's, straight as a carpenter's leaden plumb there crashed on to the top of the assailant's head a huge, polished brass bowl. The man fell, limp, senseless as a corpse. His confederate whirled on his heel, and fired his revolver twice rapidly above his head, just missing Buck.
Connie shrieked, and the next moment the big, unclean fingers had locked themselves about her throat, and she was forced to her knees, while a guttural voice said: "Scream, will you! Well, try it! This is what you get!"
For weeks Buck's ears rang with that awful, smothered cry of his young mistress, of the tortured voice of the doctor, helplessly choking, "Oh, my girl! My daughter!" But by this time Buck was three steps from the bottom, and the back of the burglar was toward him as he crouched over the struggling girl, choking the screams in her delicate throat. Like a vampire, Buck sprang from the third stair, landing on the man's back, his legs worked inside the man's elbows, pinioning the scoundrel's arms back like a trussed turkey, his arms went round the bull-like neck, and his tough young fingers closed on a sinewy throat. He clung to the creature's back like an octopus, while they rolled over and over, and the terrified girl struggled up, regaining her breath.
"Quick! quick! Miss Connie! The telephone! The police! Ring! Ring!"
Buck managed to shout. Then, "Untie the doctor's hands and feet!"
But the burglar's arms were now gripping behind him, and digging, cruel fingers pierced Buck's flesh. But the boy never relaxed his octopus hold. The tighter the big nails clutched, the tighter his own boyish fingers stiffened on the man's throat.
