Julian stepped aside (with his aunt’s eyes angrily following him) and spoke to the police officer. “Go back to the station,” he said, “and wait there till you hear from me.”

The meanly vigilant eyes of the man in plain clothes traveled sidelong from Julian to Mercy, and valued her beauty as they had valued the carpet and the chairs. “The old story,” he thought. “The nice-looking woman is always at the bottom of it; and, sooner or later, the nice-looking woman has her way.” He marched back across the room, to the discord of his own creaking boots, bowed, with a villainous smile which put the worst construction on everything, and vanished through the library door.

Lady Janet’s high breeding restrained her from saying anything until the police officer was out of hearing. Then, and not till then, she appealed to Julian.

“I presume you are in the secret of this?” she said. “I suppose you have some reason for setting my authority at defiance in my own house?”

“I have never yet failed to respect your ladyship,” Julian answered. “Before long you will know that I am not failing in respect toward you now.”

Lady Janet looked across the room. Grace was listening eagerly, conscious that events had taken some mysterious turn in her favor within the last minute.

“Is it part of your new arrangement of my affairs,” her ladyship continued, “that this person is to remain in the house?”

The terror that had daunted Grace had not lost all hold of her yet. She left it to Julian to reply. Before he could speak Mercy crossed the room and whispered to her, “Give me time to confess it in writing. I can’t own it before them—with this round my neck.” She pointed to the necklace. Grace cast a threatening glance at her, and suddenly looked away again in silence.

Mercy answered Lady Janet’s question. “I beg your ladyship to permit her to remain until the half hour is over,” she said. “My request will have explained itself by that time.”

Lady Janet raised no further obstacles. For something in Mercy’s face, or in Mercy’s tone, seemed to have silenced her, as it had silenced Grace. Horace was the next who spoke. In tones of suppressed rage and suspicion he addressed himself to Mercy, standing fronting him by Julian’s side.
