his feet. Lady Janet (hurriedly joining Horace, and fully sharing his perplexity and alarm,) took Mercy impulsively by the arm, and shook it, as if to rouse her to a sense of what she was doing. Mercy held firm ; Mercy resolutely repeated what she had said: 'Send that man out of the house.'

What has

Lady Janet lost all patience with her. come to you?' she asked sternly. Do you know what you are saying? The man is here in your interest as well as in mine; the man is here to spare you, as well as me, further annoyance and insult. And you insist— insist, in my presence-on his being sent away! What does it mean?'

"You shall know what it means, Lady Janet, in half an hour. I don't insist-I only reiterate my entreaty. Let the man be sent away!'

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 travelled sidelong from Julian to Mercy, and valued her beauty as they had valued the carpet and the chairs. The old story,' he thought. The nicelooking 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 upon everything; and vanished through the library door.

Lady Janet's high breeding restrained her from saying

R

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 towards you now.'

Lady Janet looked across the room. Grace was listening eagerly, conscious that events had taken some mysterious turn in her favour 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. 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 sus

picion, he addressed himself to Mercy, standing fronting him by Julian's side.

'Am I included,' he asked, 'in the arrangement which engages you to explain your extraordinary conduct in half an hour?'

His hand had placed his mother's wedding-present round Mercy's neck. A sharp pang wrung her as she looked at Horace, and saw how deeply she had already distressed and offended him. The tears rose in her eyes; she humbly and faintly answered him.

If you please,' was all she could say, before the cruel swelling at her heart rose and silenced her.

Horace's sense of injury refused to be soothed by such simple submission as this.

'I dislike mysteries and innuendoes,' he went on harshly. In my family circle we are accustomed to meet each other frankly. Why am I to wait half an hour for an explanation which might be given now? What am I to wait for?'

Lady Janet recovered herself as Horace spoke.

'I entirely agree with you,' she said. 'I ask, too, what are we to wait for?'

Even Julian's self-possession failed him when his aunt repeated that cruelly plain question. How would Mercy answer it? Would her courage still hold out?

'You have asked me what you have to wait for,' she said to Horace, quietly and firmly. Wait to hear something more of Mercy Merrick.'

Lady Janet listened with a look of weary disgust. 'Don't return to that!' she said. "We know enough about Mercy Merrick already.'

'Pardon me-your ladyship does not know. I am the only person who can inform you.'

( You?'

She bent her head respectfully.

'I have begged you, Lady Janet, to give me half an hour,' she went on. 6 In half an hour I solemnly engage myself to produce Mercy Merrick in this room. Lady Janet Roy, Mr. Horace Holmcroft, you are to wait for that.'

Steadily pledging herself in those terms to make her confession, she unclasped the pearls from her neck, put them away in their case, and placed it in Horace's hand. Keep it,' she said, with a momentary faltering

in her voice, until we meet again.'

Horace took the case in silence; he looked and acted like a man whose mind was paralysed by surprise. His hand moved mechanically. His eyes followed Mercy with a vacant questioning look. Lady Janet seemed, in her different way, to share the strange oppression that had fallen on him. A marked change had appeared in her since Mercy had spoken last.

"Have I your ladyship's leave,' said Mercy, respectfully,' to go to my room?'

Lady Janet mutely granted the request. Mercy's last look, before she went out, was a look at Grace. Are you satisfied now?' the grand grey eyes seemed to say mournfully. Grace turned her head aside, with a quick petulant action. Even her narrow nature opened for a moment unwillingly, and let pity in a little way, in spite of itself.

Mercy's parting words recommended Grace to Julian's care:

'You will see that she is allowed a room to wait in? You will warn her yourself when the half hour has expired?'

Julian opened the library door for her.

Well done! Nobly done!' he whispered. All my sympathy is with you-all my help is yours.'

Her eyes looked at him, and thanked him, through her gathering tears. His own eyes were dimmed. She passed quietly down the room, and was lost to him. before he had shut the door again.

CHAPTER THE TWENTY-FIRST.

THE FOOTSTEP IN THE CORRIDOR.

MERCY was alone.

She had secured one half-hour of retirement in her own room; designing to devote that interval to the writing of her confession in the form of a letter addressed to Julian Gray.

No recent change in her position had, as yet, mitigated her horror of acknowledging to Horace and to Lady Janet that she had won her way to their hearts in disguise. Through Julian only could she say the words which were to establish Grace Roseberry in her right position in the house.
