And it was that moment that Mr. Waddington chose to come in to present the green jade necklace. He was wearing his canary yellow waistcoat.

Barbara closed her sketch-book hurriedly and laid it on the table. She kept one arm over it while she received and opened the leather case where the green necklace lay on its white cushion.

"For me? Oh, it's too heavenly. How awfully sweet of you."

"Do you like it, Barbara?"

"I love it."

Compunction stung her when she thought of her drawings, especially the one where he was getting into bed. She said to herself: "I'll never do it again. Never again…. And I won't show it to Ralph."

"Put it on," he commanded, "and let me see you in it."

She lifted it from the case. She raised her arms and clasped it round her neck; she went to the looking-glass. And, after the first rapt moment of admiration, Mr. Waddington possessed himself of the uncovered sketch-book. Barbara saw him in the looking-glass. She turned, with a cry:

"You mustn't! You mustn't look at it."

"Why not?"
