She looked up at the clear dark sky where the moon hung like a huge silver air-ball.

"No, I suppose not!" she replied—"The old English word was 'Mistress.' So quaint and pretty, don't you think?"

'Oh mistress mine, where are you roaming?
Oh stay and hear! your true love's coming!'

She sang the two lines in a deliciously entrancing voice, full of youth and tenderness. With one quick stride he advanced upon her and caught her by the shoulders.

"My God, I could shake the life out of you!" he said, fiercely—"I wonder you are not afraid of me!"

She laughed, careless of his grasp.

"Why should I be? You couldn't kill me if you tried—and if you could—"

"If I could—ah, if I could!" he muttered, fiercely.

"Why then there would be another murderer added to the general world of murderers!" she said—"That's all! It's not worth it!"

Still he held her in his grip.
