“Mike,” said Lady Charles, “be an angel and run out on the landing. If you see a little man—”

“In a bowler,” said Henry and Frid.

“Yes, of course in a bowler. If you see him, don’t say anything but just come and tell Mummy, darling, will you?”

“Righto,” said Mike politely. “Is he a bum, Mummy?”

“We think so but it’s nothing to worry about. Do hurry, Mikey darling.”

Mike grinned disarmingly and began to hop out of the room on one leg.

“I can hop for miles,” he said.

“Well, run quietly for a change.”

Mike gave a Red-Indian call and began to crawl out. The twins rose in a menacing fashion. He uttered a shrill yelp and ran.

“Isn’t he heaven?” Lady Charles asked Roberta.
