Elma looked at her inquiringly.

"Is there anything you want?" asked Mrs. Leighton in answer to that expression. How often had they asked the same question uselessly within the past weeks!

Elma looked up at the white walls.

"Yes, mummy, there's one thing. I should like a large ham sandwich."

"There," said Nurse emphatically. "That's it. Now the fight is really going to begin."

"I should like to have plenty of butter on it and quite a lot of mustard," said Elma.

"Mustard?" said Mrs. Leighton helplessly. "Do you know what's been wrong with you all these weeks?"

Elma moved her eyes curiously, there being not much else that she could move. It had never dawned on her till that moment to wonder what had been wrong with her.

"No, mummy," she said, "I haven't a notion."

Mrs. Leighton looked for instructions to the nurse.
