“What shall I write?” she said. “You know how to write things down; and I don’t.”

“First put the date,” said Agatha.

“To be sure,” said Jane, writing it quickly. “I forgot that. Well?”

“Now write, ‘I am very sorry that Miss Wilson saw me when I slid down the banisters this evening. Jane Carpenter.’”

“Is that all?”

“That’s all: unless you wish to add something of your own composition.”

“I hope it’s all right,” said Jane, looking suspiciously at Agatha. “However, there can’t be any harm in it; for it’s the simple truth. Anyhow, if you are playing one of your jokes on me, you are a nasty mean thing, and I don’t care. Now, Gertrude, it’s your turn. Please look at mine, and see whether the spelling is right.”

“It is not my business to teach you to spell,” said Gertrude, taking the pen. And, while Jane was murmuring at her churlishness, she wrote in a bold hand:

“I have broken the rules by sliding down the banisters to-day with Miss Carpenter and Miss Wylie. Miss Wylie went first.”
