Peter got up and put his hands on his mother's shoulders. "Listen!" he said. "I love you. I shall always love you. No woman shall ever come between me and you." And he caught her in his arms and kissed her.

And then she bustled down-stairs to the library, where the Doctor was taking it easy for once and dipping into one of the numerous books that surrounded him. There was a smile on Mrs. Guthrie's face which was like the sun on an autumn morning.

On the way to his bedroom Peter passed the door of Ethel's room, and drew up short. He had heard her say she was going to bed early. He hadn't had many words with her since he got back. So he decided to go in and wipe off that debt, too. When he tried to open the door he found that it was locked. He started a devil's tattoo with his knuckles. "Are you there, Kid?" he shouted out.

The answer was "Yes."

"Well, then, open the door. I want to come in."

After a moment the door was opened and Ethel stood there in a very becoming peignoir. She looked extremely disconcerted and did her best to block the way into the room.

But that wouldn't do for Peter. "What's all this?" he asked. "We lock our door now, do we?"

"Yes, sometimes," said Ethel. "Why aren't you at the theatre?" She shot a surreptitious glance towards the window, which was open.

"I've been having a talk with mother," said Peter. "Hello! I see you've been trigging up your room. Frightfully swagger now, isn't it. New art, eh? You're coming on, my dear, there's no mistake about that. I'm afraid you find us all appallingly provincial, don't you?"

The broad grin on Peter's face was no new thing to Ethel. He had always pulled her leg and treated her as though she were a sort of freak. All the same, she liked his coming in and was flattered to know that he thought it worth while to bother about her. But she began to edge him to the door. He had come at a most unpropitious moment.
