Out of consideration for Aunt Maria, Pepperpot had been shut on the third floor. He would have found the separation from his beloved master and mistress most irksome if he had not discovered, on Graham's table, the box of white mice which Graham had brought from the garage during the afternoon. To pass the time Pepper amused himself by tormenting the imprisoned mice. When Graham startled him at his pleasant occupation he jumped so hurriedly from the table that he sent the box tumbling to the floor. The fall broke the box; the poor mice, mad to escape from their persecutor, went scampering down the stairs and through the hall, Pepper in pursuit and Graham frantically trying to catch them all. Of course the chase led straight to the library! Aunt Maria, at the startling interruption, dropped a precious vase she had been examining to the floor, where it lay in a hundred pieces. With a shriek and an amazing agility she climbed to the safety of the davenport. The mice circled the room and fled through another door, Pepper and Graham after them. In the pantry Graham caught Pepper; Mrs. Hicks, aided by her broom, succeeded in capturing two of the mice, but the third escaped. Gyp and Jerry listening from the banisters, their hands clapped over their mouths to suppress their laughter, heard Isobel and Mrs. Westley in the library, trying to quiet poor Aunt Maria! "We didn't promise we'd make _Pep_ behave," grumbled Graham as they shut Pepperpot, for punishment--and protection--in Jerry's clothes closet. An hour later Jerry heard Isobel, outside of the guest-room door, bidding Aunt Maria good-night. Jerry thought that she did not blame Isobel for wanting to go abroad with Aunt Maria; it would be very wonderful to travel with such a fine lady and with Peregrine! She hoped Pepper had not spoiled everything! Quiet settled over the Westley home. A door opened and shut and uncertain footsteps came down the hall. Jerry, half asleep, thought it must be the faithful and sensible Peregrine-Sarah, groping her way to the third floor after having put the Duchess to bed. Then, across the quiet pierced the wildest shrieking--a shrieking that brought back a frightened Peregrine-Sarah, Graham, leaping in two bounds down the stairway, Isobel, Mrs. Westley, Gyp and Jerry to the guest-room door! In the middle of the room, her hands clasped tragically over her heart, her mouth open for another shriek, stood Aunt Maria, trembling. Stripped of her regal trappings she made an abject picture; the snowy puff lay on her bureau and from under a nightcap, now sadly awry, straggled wisps of yellow-gray hair. Her round body was warmly clad in a humble flannelette nightdress, high-necked and long-sleeved. And, strangest of all, her face was covered with squares and strips of courtplaster!
