Horatia shut the door. “D-don’t speak too loud! Mama’s bedroom is next door. What did she say?”

“I have not seen Lady Winwood,” Mr Heron answered heavily.

“Stupid! L-Lizzie!”

He said tightly: “Only goodbye.”

“It shan’t be!” said Horatia, with determination. “L-listen, Edward! I have a p-plan!”

He looked down at her, a gleam of hope in his eyes. “I’ll do anything!” he said. “Only tell me!”

“It isn’t anything for you to do,” said Horatia. “I am g-going to do it!”

“You?” he said doubtfully. “But what can you do?”

“I d-don’t know, but I’m g-going to try. M-mind, I can’t be sure that it will succeed, but I think perhaps it m-might.”

“But what is it?” he persisted.
