If Diana--a modern Eve--hankered after the apples of new experiences, Wendy succumbed to her persuasions as readily as Adam. The little purling brook was attractive, mistresses and prefects were safely out of sight, and schoolmates, if they chanced to appear on the scene, might be bribed not to blab. In a twinkling laces were unfastened, and two stout pairs of boots stowed away among the stones, each with its stocking tucked inside; while two pairs of bare feet went splashing joyously into the brook. It was fun paddling in the little pools and scrambling over the rocks, waving a foot occasionally into a foaming fall, and dancing out on to the grass when the water grew too cold to be endured any longer. They wandered for some distance up the hill-side, supremely happy, though taking care not to allow their exuberant spirits to overflow into song. So far not a soul seemed to have noticed them--they were enjoying the sweets of undiscovered crime. Suddenly through the clear autumnal air rang out the shrill, bubbling call of the regimental whistle with which Miss Todd was wont, on country walks, to collect her scattered flock. The two sinners jumped so uneasily that Wendy slipped from a stone and splashed into a pool, with rather disastrous consequences to her skirt.
