Wardour Place, the home of Miss Constance Wardour, and the scene of the "great Diamond robbery," lies a little east from the town, away from the clamor of its mills, and the contamination of its canaille.

It is a beautiful old place, built upon a slight elevation, surrounded by stately old trees, with a wide sweep of well-kept lawn, bordered with rose thickets, and dotted here and there with great clumps of tall syringas, white lilacs, acacias, and a variety of ornamental trees and flowering shrubs.

The mansion stands some distance from the road, and is reached by a broad, sweeping drive and two footpaths that approach from opposite directions.

In the rear are orchard and gardens, and beyond these a grassy slope that curves down to meet the river, that is ever hurrying townward to seize the great mill wheels and set them sweeping round and round.

The mansion itself is a large, roomy edifice, built by a master architect. It at once impresses one with a sense of its true purpose: a home, stately, but not stiff, abounding in comfort and aristocratic ease; a place of serene repose and inborn refinement. Such, Wardour Place was intended to be; such, it has been and is.

Miss Constance Wardour, mistress of the domain and last of the race, is alone in her own favorite morning room. It is two hours since the discovery of the robbery, and during those two hours confusion has reigned supreme. Everybody, except Miss Wardour, has seemingly run wild. But Miss Wardour has kept her head, and has prevented the servants from giving the alarm upon the highway, and thus filling her house with a promiscuous mob. She has compelled them to comport themselves like rational beings; has ordered the library and dressing room to be closed, and left untouched until the proper officer shall have made proper investigations; and then she has ordered her maid to serve her with a cup of strong coffee in the morning room; and, considering the glittering wealth she has just been bereaved of, Miss Wardour looks very calm and unruffled, and sips her coffee with a relish.

Presently the door opens and a lady enters: a very fat lady, with florid complexion, restless, inquisitive, but good-humored gray eyes, and plenty of dark crinkly hair, combed low about her ears.

This is Mrs. Honor Aliston, a distant relative of Miss Wardour's, who has found a most delightful home with that young lady, ever since the death of Grandmamma Wardour, for Constance Wardour has been an orphan since her childhood.

Mrs. Aliston comes forward, rather rolls forward, and sinking, with a grunt of satisfaction, into the largest chair at hand, fixes two gray eyes upon the heiress, which that young lady, perceiving, says: "Well?"

"Don't say 'well' to me. I've just come down from the mansard," gasped the widow Aliston.

"From the mansard?"

"Yes," fanning herself briskly with the pages of an uncut magazine.

Constance laughs musically. "Why, Aunt Honor, you didn't expect to see the robbers running across the country, did you?"

"Not I," disdainfully. "I wanted to see how long it took the news to get to—Mapleton."

"Oh!" indifferently.

"And—they're coming."

"So soon!"

"So soon! and the sheriff, or constable, or coroner,—who is it that make these investigations? He's coming, at any rate, whoever he is, with a mob at his heels. Who did you send for, Con?"

"For Mr. O'Meara, of course, and—I would like to see Ray Vandyck."

"What for?"

Constance laughed. "Oh, I am fond of Ray, you know, and I think he would offer some unique suggestions; besides—dear me, auntie!" breaking off suddenly, "I wish this farce was at an end."

Mrs. Aliston's gray eyes twinkled. "Why, child, you may be thankful it's no worse. Suppose—"

"Hush, Aunt Honor. 'Walls have ears,' you know. I have half a mind to take Mr. Lamotte into my—"

"Constance Wardour, what are you thinking about? 'Take Mr. Lamotte!' that means Frank Lamotte and Madame Lamotte, and that means all the rest."

"I said 'half a mind,' auntie. I don't think the notion will ever get its growth. I think we will see the end of this affair through our own spectacles; but—hear that noise! Are they bringing a legion of people? Auntie, I don't believe you have had a cup of coffee yet."

"Don't you? Well, I have, my child. Let's go out and meet those people. They will bring all the dirt that lay loose on the highway on the soles of their boots. Con," turning suddenly, "you don't look solemn enough."

Without heeding this last remark, Constance Wardour throws open the door, and passes out and down the hall to meet the party just entering.

There is Mr. Soames, the mayor of W——, very bustling and important; Corliss, the constable, exceedingly shrewd in his own opinion, and looking on this occasion as wise as an owl; Thomas Craig, Esq., sub-editor of the Argus; and some lesser lights, who, on one pretext and another, hope to gain admittance and sate their curiosity.

"Really, Miss Wardour," begins the bustling mayor, "really, this is a sad affair! miserable affair! Must have given you a terrible fright, and then the loss!—but we will find them. Of course your jewels, such valuables, can't be kept hid from sharp detectives—a—Corliss, what had we better do first?" for Mayor Soames, like many another mayor, is about as capable of fulfilling his duties as an average ten-year-old.

Corliss, however, comes gallantly to the rescue. He is equal to any emergency; there is nothing, if you take his word as proof, that Corliss is not equal to.

"First," says Corliss, "I think we had better—ahem—investigate."

"To be sure—investigate, of course—Miss Wardour, you have—"

"Closed up the disturbed rooms," interrupts Constance, promptly. "Yes, sir; I fear you will find little there to assist you. Nelly, throw open the library."

The servant, thus commanded, took from her mistress' hand a key, unlocked the library door and threw it open; and then the farce began.

If there is anything in all our dispensations of law and order that is calculated to strike astonishment to the heart and mind of a foreigner, it is our off-hand way of conducting a police investigation. In other countries, to be a magistrate, a notary, means to be in some degree qualified for the position; to be a constable, means to possess a moderate allowance of mother wit, and a small measure of "muscular christianity;" and to discover a crime, means to follow it up with a thorough and systematic investigation. Such is not our mode. With us, to hold office, means to get a salary; and to conduct an investigation, means to maunder through some sort of farce, which gives the criminal time to make good his escape, and to permit the newspapers to seize upon and publish every item, to detail every clue, as fast as discovered; all this being in favor of the law-breakers, and detrimental to the conscientious officers of justice.

In France, they complain of too much red tape in the police department. Let them supply us out of their superabundance; we have too little.

While Corliss "investigates," the mayor delivers an impromptu oration; and Mr. Craig, of the Argus, takes notes, according to his own light.

Out of his inner consciousness, the Argus man evokes an idea, which Corliss is not slow to adopt and use as his own.

"I suppose they will have a detective down as soon as possible," says Mr. Craig, as Corliss lays one ruthless hand on an overturned chair. "If I were you, Corliss, I would leave everything exactly as I find it, for the benefit of whoever works up the case."

Corliss slowly lowers the chair to its former position, and turns upon Craig a look of offended dignity.

"Why, what did you suppose I intended to do?"

"Umph!" retorted Craig, with a disrespectful sniff, "I rather thought you intended to sit down in that chair."

Turning his back upon the flippant young man, so sadly lacking in respect for the "powers that be," Corliss pursues his investigations. He has read, in many novels and sensational newspapers, vivid descriptions of similar examinations, and he goes to work after the most approved fashion. He scrutinizes the window, the open blind, the cut pane, the hangings within and the down-trodden shrubbery without; he darts out, and dives in; he peers under every thing, over every thing, into every thing; he inspects, over and again, the mutilated writing case, or safe, from which the treasure was actually taken; and raps and sounds it as if in search of some private receptacle that the thieves had overlooked, or Miss Wardour never found out. He goes down flat upon his stomach, and scrutinizes Miss Wardour's scrupulously swept carpets, in search of a footprint in the dust that is not there.

While he performs these feats, the mayor follows him about solemnly, and full of wondering admiration; and the man of the Argus scribbles, and chuckles and grins maliciously.

Meantime, there have been other arrivals at Wardour Place; and Constance, leaving the inspectors to their own devices, is standing in her drawing-room, talking earnestly with a broad-shouldered, handsome man, who looks much surprised at the tale she is telling.

"How unfortunate, and how fortunate," he says, depositing his hat upon the table beside him. "I came here to speak of our river excursion, and lo, I am in the midst of a sensation."

Constance laughed.

"And surrounded by forlorn females," she supplemented. "Aunt Honor won't recover from the fright in a week, although she looks so fierce at present."

Mrs. Aliston, who is seated at the farthest window, half buried by the lace draperies, and looking steadfastly down the road, pops out her head to retort:

"It's time to look fierce; don't I know that those Vandals in the next room will make as big a muddle as if they were in sympathy with the burglars?"

Constance laughed easily.

"They can't do much harm, auntie; the burglars did not leave a trace; I am positive of that." Then turning to the new comer, "I am very glad you came just now, Doctor Heath; you may help me with your advice. I have sent for my lawyer, Mr. O'Meara; but, for some reason he does not come."

"Mr. O'Meara left for the city last night."

"Oh! I am sorry for that; he would be sure to know how to proceed, and who to employ. Doctor Heath you are of course acquainted in the city; tell me of a good man, a really good one. I intend to spare no expense in hunting these robbers."

"And these diamonds," from behind the curtain.

"Aunt Honor, you are like the ghost in the pantomime; come out and be one of us."

"I won't."

"Very well, then; but seriously, Doctor Heath, if I can't secure but the one, let it be the robbers. Do you know I have a fancy that if we caught them or him, it would put an end to some of our mysteries. You have not been among us very long; but, don't you think we have more than our average of crime?"

"I had not observed, Miss Wardour."

"Less than a year ago, Brant, the jeweler, was a heavy loser. Within the year, three banks in this vicinity have been robbed. Last summer, Mark Olson, a farmer, drew from the bank several thousand dollars, intending to purchase land. Half way between W—— and his home he was waylaid, knocked from his horse, robbed, and left in the road senseless. I could name to you no less than seven private residences that have been burglarized within the past ten months, and if I related to you the circumstances attending each robbery, you would be satisfied, as I am, that, in every case, the robbers knew their ground, and did not work at random."

"And you have noted each of these events so accurately, Miss Wardour, and yet, were not—warned."

"I have noted all these events, Doctor Heath, and yet—have been robbed."

Doctor Heath bends his eyes upon the floor, and remains silent; there is no possibility of reading his thoughts in his face. It is a fine face, however, and Miss Wardour must be pardoned if she takes advantage of this temporary abstraction, to gaze full at him for one moment. The close cropped thick brown hair displays a well shaped head, the forehead is broad and full, the eyes large, dark gray, and capable of almost any expression; usually they look out from his handsome face with a half contemptuous indifference to all things, that leads one to fancy those eyes may have a history; this may or may not be the case. Doctor Heath came to W—— less than a year ago, armed with a personal certificate of merit from the first of the great New York physicians, bought out the practice of a broken down old resident doctor, fitted up a handsome office, and settled down to his business. He hired a small cottage as a place of residence, installed a deaf old woman as housekeeper and maid of all work, and lived a quiet bachelor life, riding a good horse, smoking a good cigar, and growing in favor with polite W—— society.

And this is absolutely all that W—— can tell concerning Dr. Clifford Heath. What was his past, whence he came, what the length of his purse or pedigree, no one knows. People have tried to find out something—of course—but Doctor Heath has a wonderful way of setting aside the hints of the curious, and he ignores the right of W—— to know his private history, with a cool impertinence that is as exasperating as it is effectual.

As he thinks, Miss Wardour watches; but no change comes over the calm, smooth shaven face, every feature expresses firmness and strength, and nothing more.

"And so you want an able officer to take this business in hand, Miss Wardour," says Clifford Heath, at length. "If it is as you suspect, it will need a shrewd man, and you have no clue, save those that are now being inspected," with a light laugh, "by our worthy constable and his supporters."

Constance Wardour arose and came close to the table, speaking in a low voice.

"Yes, Doctor Heath, I will trust you, although I intended saying nothing of this until an officer arrived. I have a clue, slight, although it may be, it is—"

"I have a clue."

She drew from her pocket a small white roll, and unfolding it, held up for his inspection half of a fine cambric handkerchief, and a tiny stoppered vial of finest cut glass.

Doctor Heath glanced at the vial and uttered one word.

"Chloroform."

"Chloroform," repeated Miss Wardour; "when I was awakened, by the knocking at my door, I found this," shaking the fragment of cambric, "lying lightly across my face; and the vial, on the little night stand beside my bed. Aunt Honor was rapping for admittance, and when she had made me comprehend the situation, we decided that it was best to say nothing of this. What seems most strange is, that it was administered with so much care; I am affected by the smallest quantity of the drug, and an ordinary dose would have put me under medical treatment. I could not have left my bed for a week, had they given me as much as would serve only to stupify Aunt Honor there."

"No," interrupted Mrs. Aliston, once more half emerging from her window. "It would have been worse than that; I think an overdose of chloroform would kill Constance. It seems as if they knew just how much to give."

Was it fancy, or did a troubled look rest for a moment in the eyes of Doctor Heath, and on his countenance a shade of pallor?

"This is, to my mind, the most serious aspect of the affair," he said gravely. "Mrs. Aliston is right; an overdose of that drug would be fatal to you. Your life has been jeopardized. I agree with Mrs. Aliston, your investigation is in the hands of bunglers; let us hunt these fellows down."

"I will see that an officer is telegraphed for at once; but—shall I send to the regular bureau, or—how?"

"There is one man in the city, if he is in the city now, who is qualified for the position he holds. He has withdrawn himself from the regular force, and acts solely on his own responsibility. He is much sought after, and possesses wonderful abilities; some of his exploits have been truly astounding."

"And this man is—"

"Mr. Lamotte; Mr. Francis Lamotte," announced a servant.

"Show them in," said Constance, at the same time gathering up the piece of cambric and the little vial and putting them in her pocket.

Doctor Heath arose, and taking up his hat, murmured an apology.

"I have a patient at this hour, Miss Wardour, and will call again during the day. You will not stand in need of my counsel now," smilingly. "Mr. Lamotte can give you all needful advice, and he is sure to be right," and Doctor Heath bowed himself out.

"The Wardour diamonds," he muttered, as he mounted his horse. "And to think that they almost cost her her life; a skilled hand was it? Well, when the detective comes, I, too, may have a clue for him."
