“’Orrible discovery near King’s Cross—a clue at last!” yelled the newspaper-boys triumphantly.

And then, helplessly, Mrs. Bunting began to laugh. She laughed, and laughed, and laughed, rocking herself to and fro as if in an ecstasy of mirth.

“Why, father, whatever’s the matter with her?”

Daisy looked quite scared.

“She’s in ’sterics—that’s what it is,” he said shortly. “I’ll just get the water-jug. Wait a minute!”

Bunting felt very put out. Ellen was ridiculous—that’s what she was, to be so easily upset.

The lodger’s bell suddenly pealed through the quiet house. Either that sound, or maybe the threat of the water-jug, had a magical effect on Mrs. Bunting. She rose to her feet, still shaking all over, but mentally composed.

“I’ll go up,” she said a little chokingly. “As for you, child, just run down into the kitchen. You’ll find a piece of pork roasting in the oven. You might start paring the apples for the sauce.”

As Mrs. Bunting went upstairs her legs felt as if they were made of cotton wool. She put out a trembling hand, and clutched at the banister for support. But soon, making a great effort over herself, she began to feel more steady; and after waiting for a few moments on the landing, she knocked at the door of the drawing-room.

Mr. Sleuth’s voice answered her from the bedroom. “I’m not well,” he called out querulously; “I think I’ve caught a chill. I should be obliged if you would kindly bring me up a cup of tea, and put it outside my door, Mrs. Bunting.”
