“Oh yes.”
“What? Why?”
“So that it doesn’t come as a shock,” said Miss Susan calmly.
“But Mrs. Robertson told me that her Emma was going around the house looking for monsters in the cupboards! And up until now she’s always been afraid of them!”
“Did she have a stick?” said Susan.
“She’d got her father’s sword!”
“Good for her.”
