“Thank you, no, Doctor,” she said briskly, before she had time to change her mind. “I’m not easily frightened. And tomorrow I intend to equip this entire house with burglar alarms on doors and windows!” she went on defiantly. The incident, as far as she was concerned, was closed. She moved on into the alcove. The Doctor stared at her, shaking his head.

She tried the terrace door. “There, I knew it!” she said triumphantly. “Doctor—you didn’t fasten that bolt!”

The Doctor seemed a little taken aback. “Oh—I’m sorry—” he said.

“You only pushed it part of the way,” she explained. She completed the task and stepped back into the living-room. “The only thing that worries me now is that broken French window,” she said thoughtfully. “Anyone can reach a hand through it and open the latch.” She came down toward the settee where Dale was sitting. “Please, Doctor!”

“Oh—what are you going to do?” said the Doctor, coming out of a brown study.

“I’m going to barricade that window!” said Miss Cornelia firmly, already struggling to lift one end of the settee. But now Dale came to her rescue.

“Oh, darling, you’ll hurt yourself. Let me—” and between them, the Doctor and Dale moved the heavy settee along until it stood in front of the window in question.

The Doctor stood up when the dusty task was finished, wiping his hands.

“It would take a furniture mover to get in there now!” he said airily.

Miss Cornelia smiled.
