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.

"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 are 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.

"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 cases 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 paralyzed 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 vague sense of dread and distress hung like a cloud over her mind. At that memorable moment she felt her age, she looked her age, as she had never felt it or looked it yet.

"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 gray 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! n.o.bly 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 pa.s.sed quietly down the room, and was lost to him before he had shut the door again.

CHAPTER XXI. 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.

How was her confession to be addressed to him? In writing? or by word of mouth?

After all that had happened, from the time when Lady Janet's appearance had interrupted them, she would have felt relief rather than embarra.s.sment in personally opening her heart to the man who had so delicately understood her, who had so faithfully befriended her in her sorest need. But the repeated betrayals of Horace's jealous suspicion of Julian warned her that she would only be surrounding herself with new difficulties, and be placing Julian in a position of painful embarra.s.sment, if she admitted him to a private interview while Horace was in the house.

The one course left to take was the course that she had adopted.

Determining to address the narrative of the Fraud to Julian in the form of a letter, she arranged to add, at the close, certain instructions, pointing out to him the line of conduct which she wished him to pursue.

These instructions contemplated the communication of her letter to Lady Janet and to Horace in the library, while Mercy--self-confessed as the missing woman whom she had pledged herself to produce--awaited in the adjoining room whatever sentence it pleased them to p.r.o.nounce on her.

Her resolution not to screen herself behind Julian from any consequences which might follow the confession had taken root in her mind from the moment when Horace had harshly asked her (and when Lady Janet had joined him in asking) why she delayed her explanation, and what she was keeping them waiting for. Out of the very pain which those questions inflicted, the idea of waiting her sentence in her own person in one room, while her letter to Julian was speaking for her in another, had sprung to life. "Let them break my heart if they like," she had thought to herself, in the self-abas.e.m.e.nt of that bitter moment; "it will be no more than I have deserved."

She locked her door and opened her writing-desk. Knowing what she had to do, she tried to collect herself and do it.

The effort was in vain. Those persons who study writing as an art are probably the only persons who can measure the vast distance which separates a conception as it exists in the mind from the reduction of that conception to form and shape in words. The heavy stress of agitation that had been laid on Mercy for hours together had utterly unfitted her for the delicate and difficult process of arranging the events of a narrative in their due sequence and their due proportion toward each other. Again and again she tried to begin her letter, and again and again she was baffled by the same hopeless confusion of ideas.

She gave up the struggle in despair.

A sense of sinking at her heart, a weight of hysterical oppression on her bosom, warned her not to leave herself unoccupied, a prey to morbid self-investigation and imaginary alarms.

She turned instinctively, for a temporary employment of some kind, to the consideration of her own future. Here there were no intricacies or entanglements. The prospect began and ended with her return to the Refuge, if the matron would receive her. She did no injustice to Julian Gray; that great heart would feel for her, that kind hand would be held out to her, she knew. But what would happen if she thoughtlessly accepted all that his sympathy might offer? Scandal would point to her beauty and to his youth, and would place its own vile interpretation on the purest friendship that could exist between them. And _he_ would be the sufferer, for _he_ had a character--a clergyman's character--to lose. No. For his sake, out of grat.i.tude to _him_, the farewell to Mablethorpe House must be also the farewell to Julian Gray.
