Charles put the card carefully into his pocket-book. "We'll see," he said. "Do I understand that you propose to clean all the rooms of the house for us?"

"I'm sure I shall be pleased to, sir, but if you're satisfied, "awing seen what 'as been effected under your own eye…

"Oh no!" Charles said pleasantly. "For all I know it might break down before it had gone over half the house." Mr. Fripp looked reproachful. "This here cleaner," he said, "is constructed in such a way that it can't go wrong. I should mention that we give a year's guarantee with it, as is usual. But I shall be pleased to take it over every room in the 'ouse, to convince you, sir, of the truth of all I say."

"Excellent," said Charles. "And in case I make up my mind to buy it I'll send my man up to watch you, so that he will know in future how to manipulate it."

"That," said Mr. Fripp, "is as you like, sir, but I should like to assure you that a child could work this here cleaner."

"Nevertheless," said Charles, stepping to the bell-rope, and jerking it sharply, "I should like Bowers to - observe what you do."

Those quick-glancing eyes darted to his face for an instant. "I'm sure I shall be pleased to show him all I can, sir," Mr. Fripp said, not quite so enthusiastically.

Charles' smile was a little grim. When Bowers appeared in answer to the bell, he told him that he was to accompany Mr. Fripp from room to room, and closely to watch all he did. Mr. Fripp looked at him sideways.

"Yes, sir," Bowers said, a trifle perplexed. "But I haven't served the sweet yet, sir."

"Never mind," said Charles. "We'll manage on our own. You stay with Mr. Fripp — in case his cleaner goes out of action. And just see that he doesn't knock the panelling with it. We don't want any scratches."
