Peachy's place at the dinner-table was empty that day, and her meal was sent up to the sanatorium upon a tray. Miss Bickford had told her side of the story to Miss Rodgers, who agreed that discipline must be maintained, and ordered the detention of the prisoner until she showed symptoms of repentance. Meanwhile Peachy, still in an utterly rebellious frame of mind, stayed upstairs, determined not to give way. It was dull, undoubtedly, to be banished to solitary confinement, for there was not even a book in the room to amuse her. Her own thoughts were her sole occupation. She had a very fertile brain, however, and suddenly a most brilliant suggestion occurred to her. The sanatorium was on the top story of the Villa Camellia, and by peeping from its window she could command a view of the iron balcony that fronted the rooms below. She calculated that she was probably exactly above dormitory 10, occupied by Joan, Esther, Mary, and Agnes, and that these chums would later on be engaged there at their preparation. With a little ingenuity it should be possible to communicate with them. She unfortunately had neither pencil nor paper with her, so could not write a note, but she took off her brooch and fastened it to the end of a long piece of string, which by extra good luck happened to be in her pocket. When she judged that the right moment had arrived she lowered her signal so that it would tap on the balcony. There was, of course, a certain amount of risk about the venture, for she might have miscalculated, and be dropping her token into the midst of enemies instead of friends. Greatly to her relief, however, Agnes appeared through the French window, and, after examining the brooch with apparent surprise, glanced upwards and saw Peachy's face. She gave a comprehensive smile, put her fingers on her lips for silence, bolted into her dormitory, and returned with a package of chocolate which she tied firmly to the end of the string, then waved her hand and darted back to her preparation. Peachy drew up her present, chuckling with delight. She felt almost like a captive of the Middle Ages, and was beginning to plan a romantic escape down an improvised rope ladder, when it occurred to her that she would scarcely know what to do with her liberty if she regained it. "Botheration!" she mused. "Unless I square things up I can't walk in to tea, and I can't haunt the garden like a wandering ghost, and I've no money to pay my passage on the steamer, so I can't go home to Naples. Nothing for it but to stay here, I suppose, and see who gets tired out first." When the Camellia Buds were able to meet together again at a secret conclave in the garden, Agnes announced the important fact of having established communication with the prisoner. After an animated discussion they decided to write her a round-robin letter and set forth their idea of the situation. Each composed a sentence in turn, and Lorna acted as scribe. It ran thus: _The Grotto._
