The moment she was safely out of the way the invalid sprang up and resumed her interrupted toilet. Diana had suffered from nettle-rash several times before, and the treatment had not included stopping in bed or even staying indoors. Her complaint was really more in the nature of dyspepsia. She felt as if fresh air would do her good. She did not dare to walk downstairs in case she might meet anybody, so she decided to adopt the method she had found effective last autumn, and climb out through the window and down the ivy. Lessons were in progress, so nobody would be in the garden to watch her, except Miss Carr and Miss Ormrod, who would probably be engaged with the horse or the hens. She swung herself out, therefore, and let herself down by the thick stems. Then she dodged round the house to the bicycle-shed. She did not yet possess a machine of her own, but Wendy's stood handy, and she knew her chum well enough to borrow it. She wheeled it through the back gate, fortunately without meeting Miss Carr, and then set off at top-speed for Petteridge Court. Mrs. Burritt was naturally much surprised to see her young cousin turn up in so unexpected a fashion, and with a rash on her face, but she did the most sensible thing in the circumstances: she put Diana to bed, and sent to Dunswick for a doctor. He arrived during the course of the afternoon, and, after a careful examination of his patient, pronounced her complaint to be nettle-rash. "There's not a doubt about it!" he declared. "You need not be in the least afraid that it's measles." Armed with a medical certificate to that effect, Mrs. Burritt motored over to Pendlemere Abbey to patch up peace with Miss Todd. Partly for reasons of health, and partly to let the storm blow over, she kept Diana at Petteridge until the rash had entirely disappeared and the girl seemed in her absolutely normal condition. Mrs. Burritt took her back on the understanding that bygones should be bygones, and a fresh start should be made without any reference to former delinquencies. Miss Todd received Diana quite amiably, but insisted upon her having a carbolic bath, and herself washed her hair with strong disinfectant soap. The clothes she had worn disappeared mysteriously for some days, and were then returned from the stoving department of the Glenbury Sanitation Office. Diana made no comments at head-quarters, but laughed to herself. "I'm sure Toddlekins believes I've had measles," she confided to Wendy. "Of course she does. She said she hadn't the least doubt about it, and that you hadn't eaten anything which could have caused you to have nettle-rash." "What would she say if she knew about the sausages?" queried Diana.
