"Did it strike you last evening," he went on, "that she was ... well ... er ... that she was a bit on to things?"

"Yes ... it did."

"Well ... er ... have you any notion why she was like that ... all at once ... so suddenly?"

Belinda dropped a pebble into a little pool in the rocks just below her. She leaned over looking after it. Then she dropped in another. She was smiling secretly. Morris turned his head, as she did not answer. This smile nettled him somehow.

"Well...? Speak up, can't you?" he said sharply.

Belinda dusted her fingers daintily on her handkerchief, then laced them behind her head. This gesture drew the thin silk of her blouse tight over her round breasts. The little hollow behind her waist as she leaned against the dark rock was just large enough for a man's arm. She looked down sideways at him from under her thick, white lids and the garnet sparkles came into her eyes.

She passed it to him coolly.

"Yesterday ... when we were in the library together," she said, "I ... heard a chair move ... in the next room...."

"What?" cried Loring.

He sat erect. His face went scarlet, then white.
