She was sitting in the full light of an unshaded lamp as he entered the room. Her black silk dress was the perfection of simplicity; its sombre hues relieved only by the white collar which encircled her slender throat. Her pale face looked of an ivory whiteness, in contrast to the dark, deep eyes, and arched brows of sombre brown.

The lady pronounced herself perfectly satisfied with all the arrangements that had been made for her comfort.

"I am in London on business of importance," she said; "and shall, therefore, receive very little company; but I may have to hold many interviews with men of business, and I trust that my affairs may not be made the subject of curiosity or gossip, either in this house or outside it."

Mr. Mulck declared that he was the last person in the world to talk; and that his two servants were both elderly women, the very pink of steadiness and propriety.

Having said this, he took his leave; and as he did so, stole one more glance at the beautiful stranger.

She had fallen into an attitude which betrayed complete abstraction of mind. Her elbow rested on the table by her side; her eyes were shaded by her hand.

Upon that white, slender hand, Jacob Mulck saw diamonds such as are not often seen upon the fingers of the inhabitants of Percy Street. Mr.

Mulck occasionally dealt in diamonds; and he knew enough about them to perceive at a glance that the rings worn by his lodger were worth a small fortune.

"Humph!" muttered Mr. Mulck, as he returned to his comfortable sitting-room; "those diamonds tell a tale. There's something mysterious about this lodger of mine. However, my rent will be safe--that's one comfort."

While the landlord was musing thus, the lodger was employed in a manner which might well have awakened his curiosity, could he have beheld her at that moment.

She had fallen on her knees before a low easy-chair--her face buried in her hands, her slender frame shaken by passionate sobs.

"My child!" she exclaimed, in almost inarticulate murmurs; "my beloved, my idol!--it is so bitter to be absent from you! so bitter! so bitter!"

Early on the morning after her arrival in London, Honoria Eversleigh, otherwise Mrs. Eden, went in a cab to the office of an individual called Andrew Larkspur, who occupied dingy chambers in Lyon's Inn.

The science of the detective officer had not, at that time, reached its present state of perfection; but even then there were men who devoted their lives to the work of private investigations, and the elucidation of the strange secrets and mysteries of social life.

Such a man was Andrew Larkspur, late Bow Street runner, now hanger-on of the new detective police. He was renowned for his skill in the prosecution of secret service; and it was rumoured that he had amassed a considerable fortune by his mysterious employment.

He was not a man who openly sought employers. His services were in great request among a certain set of people, and he had little idle time on his hands. His name was painted in dirty white letters on the black door of his dingy chambers on a fourth story. On this door he called himself, "_Andrew Larkspur, Commission Agent_."

It will be seen by-and-by how Honoria Eversleigh had become acquainted with the fact of this man's existence.

She went alone to seek an interview with him. She had found herself compelled to confide in Jane Payland to a very considerable extent; but she did not tell that attendant more than she was obliged to tell of the dark business which had brought her to London.

She was fortunate enough to find Mr. Andrew Larkspur alone, and disengaged. He was a little, sandy-haired man, of some sixty years of age, spare and wizened, with a sharp nose, like a beak, and thin, long arms, ending in large, claw-like hands, that were like the talons of a bird of prey. Altogether, Mr. Lark spur had very much of the aspect of an elderly vulture which had undergone partial transformation into a human being.

Honoria was in no way repelled by the aspect of this man. She saw that he was clever; and fancied him the kind of person who would be likely to serve her faithfully.

"I have been informed that you are skilled in the prosecution of secret investigations," she said; "and I wish to secure your services immediately. Are you at liberty to devote yourself to the task I wish to be performed by you?"

Mr. Larkspur was a man who rarely answered even the simplest question until he had turned the subject over in his mind, and carefully studied every word that had been said to him.

He was a man who made caution the ruling principle of his life, and he looked at every creature he encountered in the course of his career as an individual more or less likely to take him in.

The boast of Mr. Larkspur was, that he never had been taken in.

"I've been very near it more than once," he said to his particular friends, when he unbent so far as to be confidential.

"I've had some very narrow escapes of being taken in and done for as neatly as you please. There are some artful dodgers, whose artful dodging the oldest hand can scarcely guard against; but I'm proud to say not one of those artful dodgers has ever yet been able to get the better of me. Perhaps my time is to come, and I shall be bamboozled in my old age."

Before replying to Honoria's inquiry, Andrew Larkspur studied her from head to foot, with eyes whose sharp scrutiny would have been very unpleasant to anyone who had occasion for concealment.

The result of the scrutiny seemed to be tolerably satisfactory, for Mr.

Larkspur at last replied to his visitor's question in a tone which for him was extremely gracious.

"You want to know whether you can engage my services," he said; "that depends upon circumstances."

"Upon what circumstances?"

"Whether you will be able to pay me. My hands are very full just now, and I've about as much business as I can possibly get through."

"I shall want you to abandon all such business, and to devote yourself exclusively to my service," said Honoria.

"The deuce you will!" exclaimed Mr. Larkspur. "Do you happen to know what my time is worth?"

Mr. Larkspur looked positively outraged by the idea that any one could suppose they could secure a monopoly of his valuable services.

"That is a question with which I have no concern," answered Honoria, coolly. "The work which I require you to do will most likely occupy all your time, and entirely absorb your attention. I am quite prepared to pay you liberally for your services, and I shall leave you to name your own terms. I shall rely on your honour as a man of business that those terms will not be exorbitant, and I shall accede to them without further question."

"Humph!" muttered the suspicious Andrew. "Do you know, ma'am, that sounds almost too liberal? I'm an old stager, ma'am, and have seen a good deal of life, and I have generally found that people who are ready to promise so much beforehand, are apt not to give anything when their work has been done."

"The fact that you have been cheated by swindlers is no reason why should insult me," answered Honoria. "I wished to secure your services; but I cannot continue an interview in which I find my offers met by insolent objections. There are, no doubt, other people in London who can assist me in the business I have in hand. I will wish you good morning."

She rose, and was about to leave the room. Mr. Larkspur began to think that he had been rather too cautious; and that perhaps, this plainly-attired lady might be a very good customer.

"You must excuse me, ma'am," he said, "if I'm rather a suspicious old chap. You see, it's the nature of my business to make a man suspicious.

If you can pay me for my time, I shall be willing to devote myself to your service; for I'd much rather give my whole mind to one business, than have ever so many odds and ends of affairs jostling each other in my brain. But the fact of it is, ladies very seldom have any idea what business is: however clever they may be in other matters--playing the piano, working bead-mats and worsted slippers, and such like. Now, I dare say you'll open your eyes uncommon wide when I tell you that my business is worth nigh upon sixteen pound a week to me, taking good with bad; and though you mayn't be aware of it, ma'am, having, no doubt, given your mind exclusive to Berlin wool, and such like, sixteen pound a week is eight hundred a year."

Mr. Larkspur, though not much given to surprise, was somewhat astonished to perceive that his lady-visitor did not open her eyes any wider on receiving this intelligence.

"If you have earned eight hundred a year by your profession," she returned, quietly, "I will give you twenty pounds a week for your exclusive services, and that will be a thousand and forty pounds a year."

This time, Andrew Larkspur was still more surprised, though he was so completely master of himself as to conceal the smallest evidence of his astonishment.

Here was a woman who had not devoted her mind to Berlin wool-work, and whose arithmetic was irreproachable!

"Humph!" he muttered, too cautious to betray any appearance of eagerness to accept an advantageous offer. "A thousand a year is very well in its way; but how long is it to last? If I turn my back upon this business here, it'll all tumble to pieces, and then, where shall I be when you have done with me?"

"I will engage you for one year, certain."

"That won't do, ma'am; you must make it three years, certain."

"Very well; I am willing to do that," answered Honoria. "I shall, in all probability, require your services for three years."

Mr. Larkspur regretted that he had not asked for an engagement of six years.
