Search the study as he would, he could not find it. He remembered distinctly that Lady had been panting as she slunk out of the room. And dogs that are carrying things in their mouths cannot pant. She had not taken the head away with her. The absence of the head only deepened the whole annoying domestic mystery. He gave up trying to solve any of the puzzle--from Lady's incredible vandalism to this newest turn of the affair. Not until two days later could Lad bring himself to risk a meeting with Lady, the cause and the witness of his beating. Then, yearning for a sight of her and for even her grudged recognition of his presence, after his forty-eight hours of isolation, he sallied forth from the house in search of her. He traced her to the cool shade of a lilac clump near the outbuildings. There, having with one paw dug a little pit in the cool earth, she was curled up asleep under the bushes. Stretched out beside her was Knave. Lad's spine bristled at sight of his foe. But ignoring him, he moved over to Lady and touched her nose with his own in timid caress. She opened one eye, blinked drowsily and went to sleep again. But Lad's coming had awakened Knave. Much refreshed by his nap, he woke in playful mood. He tried to induce Lady to romp with him, but she preferred to doze. So, casting about in his shallow mind for something to play with, Knave chanced to remember the prize he had hidden beneath the chicken-house. Away he ambled, returning presently with the eagle's head between his teeth. As he ran, he tossed it aloft, catching it as it fell--a pretty trick he had long since learned with a tennis-ball. Lad, who had lain down as near to sleepily scornful Lady as he dared, looked up and saw him approach. He saw, too, with what Knave was playing; and as he saw, he went quite mad. Here was the thing that had caused Lady's interrupted punishment and his own black disgrace. Knave was exploiting it with manifest and brazen delight. For the second time in his life--and for the second time in three days--Lad broke the law. He forgot, in a trice, the command "Let him alone!" And noiseless, terrible, he flew at the gamboling Knave. Knave was aware of the attack, barely in time to drop the eagle's head and spring forward to meet his antagonist. He was three years Lad's junior and was perhaps five pounds heavier. Moreover, constant exercise had kept him in steel-and-whale-bone condition; while lonely brooding at home had begun of late to soften Lad's tough sinews. Knave was mildly surprised that the dog he had looked on as a dullard and a poltroon should have developed a flash of spirit. But he was not at all unwilling to wage a combat whose victory must make him shine with redoubled glory in Lady's eyes.
