He ushered Margaret into a private sitting-room leading out of the hall, and then closed the door behind him. The disappointed waiter lingered upon the door-mat: but the George is a well-built house, and that waiter lingered in vain.

"You want to see Mr. Dunbar?" he said.

"Yes, sir!"

"He is very much fatigued by yesterday's business, and he declines to see you. What is your motive for being so eager to see him?"

"I will tell that to Mr. Dunbar himself."

"You are _really_ the daughter of Joseph Wilmot? Mr. Dunbar seems to doubt the fact of his having had a daughter."

"Perhaps so. Mr. Dunbar may have been unaware of my existence until this moment. I did not know until last night what had happened."

She stopped for a moment, half-stifled by a hysterical sob, which she could not repress: but she very quickly regained her self-control, and continued, slowly and deliberately, looking earnestly in the young man's face with her clear brown eyes, "I did not know until last night that my father's name was Wilmot; he had called himself by a false name--but last night, after hearing of the--the--murder"--the horrible word seemed to suffocate her, but she still went bravely on--"I searched a box of my father's and found this."

She took from her pocket the letter directed to Norfolk Island, and handed it to the lawyer.

"Read it," she said; "you will see then how my father had been wronged by Henry Dunbar."

Arthur Lovell unfolded the worn and faded letter. It had been written five-and-twenty years before by Sampson Wilmot. Margaret pointed to one pa.s.sage on the second page.

_"Your bitterness against Henry Dunbar is very painful to me, my dear Joseph; yet I cannot but feel that your hatred against my employer's son is only natural. I know that he was the first cause of your ruin; and that, but for him, your lot in life might have been very different. Try to forgive him; try to forget him, even if you cannot forgive. Do not talk of revenge. The revelation of that secret which you hold respecting the forged bills would bring disgrace not only upon him, but upon his father and his uncle. They are both good and honourable men, and I think that shame would kill them. Remember this, and keep the secret of that painful story."_

Arthur Lovell's face grew terribly grave as he read these lines. He had heard the story of the forgery hinted at, but he had never heard its details. He had looked upon it as a cruel scandal, which had perhaps arisen out of some trifling error, some unpaid debt of honour; some foolish gambling transaction in the early youth of Henry Dunbar.

But here, in the handwriting of the dead clerk, here was the evidence of that old story. Those few lines in Sampson Wilmot's letter suggested a _motive_.

The young lawyer dropped into a chair, and sat for some minutes silently poring over the clerk's letter. He did not like Henry Dunbar. His generous young heart, which had yearned towards Laura's father, had sunk in his breast with a dull, chill feeling of disappointment, at his first meeting with the rich man.

Still, after carefully sifting the evidence of the coroner's inquest, he had come to the conclusion that Henry Dunbar was innocent of Joseph Wilmot's death. He had carefully weighed every sc.r.a.p of evidence against the Anglo-Indian; and had deliberately arrived at this conclusion.

But now he looked at everything in a new light. The clerk's letter suggested a motive, perhaps an adequate motive. The two men had gone down together into that silent grove, the servant had threatened his patron, they had quarrelled, and--

No! the murder could scarcely have happened in this way. The a.s.sa.s.sin had been armed with the cruel rope, and had crept stealthily behind his victim. It was not a common murder; the rope and the slip-knot, the treacherous running noose, hinted darkly at Oriental experiences: somewhat in this fashion might a murderous Thug have a.s.sailed his unconscious victim.

But then, on the other hand, there was one circ.u.mstance that always remained in Henry Dunbar's favour--that circ.u.mstance was the robbery of the dead man's clothes. The Anglo-Indian might very well have rifled the pocket-book, and left it empty upon the scene of the murder, in order to throw the officers of justice upon a wrong scent. That would have been only the work of a few moments.

But was it probable--was it even possible--that the murderer would have lingered in broad daylight, with every chance against him, long enough to strip off the garments of his victim, in order still more effectually to hoodwink suspicion? Was it not a great deal more likely that Joseph Wilmot had spent the afternoon drinking in the tap-room of some roadside public-house, and had rambled back into the grove after dark, to meet his death at the hands of some every-day a.s.sa.s.sin, bent only upon plunder?

All these thoughts pa.s.sed through Arthur Lovell's mind as he sat with Sampson's faded letter in his hands. Margaret Wilmot watched him with eager, scrutinizing eyes. She saw doubt, perplexity, horror, indecision, all struggling in his handsome face.

But the lawyer felt that it was his duty to act, and to act in the interests of his client, whatever vaguely-hideous doubts might arise in his own breast. Nothing but his _conviction_ of Henry Dunbar's guilt could justify him in deserting his client. He was not convinced; he was only horror-stricken by the first whisper of doubt.

"Mr. Dunbar declines to see you," he said to Margaret; "and I do not really see what good could possibly arise out of an interview between you. In the meantime, if you are in any way distressed--and you must most likely need a.s.sistance at such a time as this--he is quite ready to help you: and he is also ready to give you permanent help if you require it."

He opened Henry Dunbar's purse as he spoke, but the girl rose and looked at him with icy disdain in her fixed white face.

"I would sooner crawl from door to door, begging my bread of the hardest strangers in this cruel world--I would sooner die from the lingering agonies of starvation--than I would accept help from Henry Dunbar. No power on earth will ever induce me to take a sixpence from that man's hand."

"Why not?"

"_You_ know why not. I can see that knowledge in your face. Tell Mr.

Dunbar that I will wait at the door of this house till he comes out to speak to me. I will wait until I drop down dead."

Arthur Lovell went back to his client, and told him what the girl said.

Mr. Dunbar was walking up and down the room, with his head bent moodily upon his breast.

"By heavens!" he cried, angrily, "I will have this girl removed by the police, if----"

He stopped abruptly, and his head sank once more upon his breast.

"I would most earnestly advise you to see her," pleaded Arthur Lovell; "if she goes away in her present frame of mind, she may spread a horrible scandal against you. Your refusing to see her will confirm the suspicions which----"

"What!" cried Henry Dunbar; "does she dare to suspect me?"

"I fear so."

"Has she said as much?"

"Not in actual words. But her manner betrayed her suspicions. You must not wonder if this girl is unreasonable. Her father's miserable fate must have been a terrible blow to her."

"Did you offer her money?"

"I did."

"And she----"

"She refused it."

Mr. Dunbar winced, as if the announcement of the girl's refusal had stung him to the quick.

"Since it must be so," he said, "I will see this importunate woman. But not to-day. To-day I must and will have rest. Tell her to come to me to-morrow morning at ten o'clock. I will see her then."

Arthur Lovell carried this message to Margaret.

The girl looked at him with an earnest questioning glance.

"You are not deceiving me?" she said.

"No, indeed!"

"Mr. Dunbar said that?"

"He did."

"Then I will go away. But do not let Henry Dunbar try to deceive me! for I will follow him to the end of the world. I care very little where I go in my search for the man who murdered my father!"
