now would be fatal. Father—"

"Hush!" broke in the other voice, in a masculine tone of repressed intensity. "Do not forget that success depends upon your prudence. One whisper of what you are about, and the whole scheme is destroyed."

"I will be careful; only do you think that all is going well and as we planned it?"

"It will not be my fault if it does not," was the reply, uttered with an accent so sinister I was conscious of a violent surprise when, in the next instant, the other, with a burst of affectionate fervor, cried in an ardent tone:

"Oh, how good you are, and what a comfort you are to me!"

I was just pondering over the incongruity thus presented, when the servant returned with my card.

"Mr. Benson wishes to know the nature of your business," said he, in a voice I was uncomfortably conscious must penetrate to the next room and awake its inmates to a knowledge of my proximity.

"Let me have the card," said I; and taking it, I added to my words the simple phrase, "On behalf of the Constable of the town," remembering I had heard the postmaster say this position was held by his brother. "There," said I, "carry that back to your master."

The servant took the card, glanced down at the words I had written, started and hastily drew back. "You had better come," said he, leading the way into the hall.

I was only too glad to comply; in fact, escape from that room seemed imperative. But just as I was crossing the threshold, a sudden, quick cry, half joyful, half fearful, rose behind me, and turning, I met the eyes of a young lady peering upon me from a lifted portière, with an expression of mingled terror and longing that would have astonished me greatly, if it had not instantly disappeared at the first sight of my face.

"Pardon me," she exclaimed, drawing back with an embarrassed movement into the room from which she had emerged. But soon recovering herself, she stepped hastily forward, and ignoring me, said to the servant at my side: "Jonas, who is this gentleman, and where are you taking him?"

With a bow, Jonas replied: "He comes on business, miss, and Mr. Benson consents to see him."

"But I thought my father had expressly commanded that no one was to be allowed to enter the library to-day," she exclaimed, but in a musing tone that asked for no response. And hastily as we passed down the hall, I could not escape the uneasy sense that her eager eyes were following us as we went.

"Too much emotion for so small a matter, and a strange desire on the part of every one to keep Mr. Benson from being intruded upon to-day," was my mental comment. And I was scarcely surprised when upon our arrival at the library door we found it locked. However, a knock, followed by a few whispered words on the part of the servant, served to arouse the hermit within, and with a quick turn of the key, the door flew back on its hinges, and the master of the house stood before me.

It was a moment to be remembered: first, because the picture presented to my eyes was of a marked and impressive character; and secondly, because something in the expression of the gentleman before me showed that he had received a shock at my introduction which was not to be expected after the pains which had been taken to prepare his mind for my visit. He was a tall, remarkable-looking man, with a head already whitened, and a form which, if not bowed, had only retained its upright carriage by means of the indomitable will that betrayed itself in his eyes. Seen against the rich background of the stained-glass window that adorned one end of the apartment, his stern, furrowed face and eagerly repellant aspect imprinted itself upon me like a silhouette, while the strong emotion I could not but detect in his bearing, lent to the whole a poetic finish that made it a living picture which, as I have said, I have never been able to forget.

"You have come from the constable of the town," said he, in a firm, hard tone, impressive as his look. "May I ask for what purpose?"

Looking around, I saw the servant had disappeared. "Sir," said I, gathering up my courage, as I became convinced that in this case I had a thoroughly honest man to deal with, "you are going to give a fancy ball to-night. Such an event is a novelty in these parts, and arouses much curiosity. Some of the men about town have even been heard to threaten to leap the fences and steal a look at your company, whether you will or not. Mr. White wants to know whether you need any assistance in keeping the grounds clear of all but your legitimate guests; if so, he is ready to supply whatever force you may need."

"Mr. White is very kind," returned Mr. Benson, in a voice which, despite his will-power, showed that his agitation had in some unaccountable way been increased by my communication. "I had not thought of any such contingency," he murmured, moving over to a window and looking out. "An invasion of rowdies would not be agreeable. They might even find their way into the house." He paused and cast a sudden look at me. "Who are you?" he abruptly asked.

The question took me by surprise, but I answered bravely if not calmly: "I am a man who sometimes assists Mr. White in the performance of his duties, and in case you need it, will be the one to render you assistance to-night. A line to Mr. White, if you doubt me——"

A wave of his meagre hand stopped me. "Do you think you could keep out of my house to-night, any one I did not wish to enter?" he asked.

"I should at least like to try."

"A ticket is given to every invited guest; but if men are going to climb the fences, tickets will amount to but little."

"I will see that the fences are guarded," cried I, gratified at the prospect of being allowed upon the scene of action. "I can hinder any one from coming in that way, if——" Here I paused, conscious of something, I could hardly say what, that bade me be cautious and weigh my words well. "If you desire it and will give me the authority to act for you," I added in a somewhat more indifferent tone.

"I do desire it," he replied shortly, moving over to the table and taking up a card. "Here is a ticket that will insure you entrance into the grounds; the rest you will manage without scandal. I do not want any disturbance, but if you see any one hanging about the house or peering into the windows or attempting to enter in any way except through the front door, you are to arrest them, no matter who they are. I have an especial reason for desiring my wishes attended to in this regard," he went on, not noticing the preoccupation that had seized me, "and will pay well if on the morrow I find that every thing has gone off according to my desires."

"Money is a powerful incentive to duty," I rejoined, with marked emphasis, directing a sly glance at the mirror opposite, in whose depths I had but a moment before been startled by the sudden apparition of the pale and strongly agitated face of young Mr. Benson, who was peering from a door-way half hidden by a screen at our back. "I will be on hand to-night." And with what I meant to be a cynical look, I made my bow and disappeared from the room.

As I expected, I was met at the front door by Mr. Hartley. "A word with you," said he. "Jonas tells me you are from the constable of the town. May I ask what has gone amiss that you come here to disturb my father on a day like this?"

His tone was not unkind, his expression not without suavity. If I had not had imprinted on my memory the startling picture of his face as I had seen it an instant before in the mirror, I should have been tempted to believe in his goodness and
