The inexorable child-logic rose like an unyielding rampart before Octavian’s scared pleadings. Before he could think of any fresh line of appeal his energies were called out in another direction. Olivia had slid off the roof and fallen with a soft, unctuous splash into a morass of muck and decaying straw. Octavian scrambled hastily over the pigsty wall to her rescue, and at once found himself in a quagmire that engulfed his feet. Olivia, after the first shock of surprise at her sudden drop through the air, had been mildly pleased at finding herself in close and unstinted contact with the sticky element that oozed around her, but as she began to sink gently into the bed of slime a feeling dawned on her that she was not after all very happy, and she began to cry in the tentative fashion of the normally good child. Octavian, battling with the quagmire, which seemed to have learned the rare art of giving way at all points without yielding an inch, saw his daughter slowly disappearing in the engulfing slush, her smeared face further distorted with the contortions of whimpering wonder, while from their perch on the pigsty roof the three children looked down with the cold unpitying detachment of the Parcae Sisters.
