“I shall do something which I am not accustomed to doing, but I must do it for the sake of the school,” said Mrs Hazlitt. “I shall open Penelope’s letter before it goes, and acquaint myself with the contents.”

Miss Duke gave a start.

“You will not do that,” she said. “It would distress Penelope very much.”

“She need never know. If the letter is straightforward and above board, nothing will occur. If the spirit of mischief—nay, more, of intrigue—is abroad, the sooner I can nip it in the bud, the better. I sent for you to consult you. I am within my rights in this matter. Don’t say a word to any one. I think that is all.”

“I am very much distressed,” said Deborah. “I wish you would not do this thing.”

“I have made up my mind, dear friend; we will not argue the point. I will read the contents of the letter, and it shall reach its destination if there is nothing in it. No harm will be done. If there is mischief in it, I shall at least know where I stand.”

Deborah sighed profoundly and left the room.

Now, upstairs a girl, who had hastily finished a hasty scrawl and had thrust it into its envelope, was busily engaged putting on her hat and drawing some cotton gloves over her hands.

“I daren’t put the letter into the post box,” she said. “I wish Deborah hadn’t come into my room; she saw quite well that I was writing. I must manage somehow to get to the village and will post the letter myself.”

She flew downstairs. A minute later, she was out of doors. She looked swiftly round her; there was not a soul in sight. The children, who were her constant companions, were playing happily in the distant woods. The girls whom she trusted were in the Queen Anne parterre or in the Queen Elizabeth garden. All the world seemed still and sleepy. Penelope made a hasty calculation. Mrs Hazlitt’s oak parlour looked out on the Queen Anne parterre. There was no one to see her. The village was a mile away; yes, she could get there; she would get there. By running fast she would accomplish this feat and yet be back just within time for afternoon school.
