"I know I could," answered Ermengarde, and she ran to the door—opened it softly—put her head out into the darkness, and listened. Then she went back to Sara.
"The lights are out. Everybody 's in bed. I can creep—and creep—and no one will hear."
It was so delightful that they caught each other's hands and a sudden light sprang into Sara's eyes.
"Ermie!" she said. "Let us pretend! Let us pretend it 's a party! And oh, won't you invite the prisoner in the next cell?"
"Yes! Yes! Let us knock on the wall now. The jailer won't hear."
Sara went to the wall. Through it she could hear poor Becky crying more softly. She knocked four times.
"That means, 'Come to me through the secret passage under the wall,' she explained. 'I have something to communicate.'"
Five quick knocks answered her.
"She is coming," she said.
Almost immediately the door of the attic opened and Becky appeared. Her eyes were red and her cap was sliding off, and when she caught sight of Ermengarde she began to rub her face nervously with her apron.
"Don't mind me a bit, Becky!" cried Ermengarde.
"Miss Ermengarde has asked you to come in," said Sara, "because she is going to bring a box of good things up here to us."
Becky's cap almost fell off entirely, she broke in with such excitement.
