THE HEART OF THE PUZZLE.

The next morning I swallowed my pride and sought out Durbin. He had superintended the removal of Mrs. Jeffrey\'s effects from the southwest chamber, and should know, if any one, where this filigree ball was now to be found. Doubtless it had been returned with the other things to Mr. Jeffrey, and yet, who knows? Durbin is sly and some inkling of its value as a clue may have entered his mind. If so, it would be anywhere but in Mr. Jeffrey\'s or Miss Tuttle\'s possession.

To test my rival\'s knowledge of and interest in this seemingly trivial object, I stooped to what I can but consider a pardonable subterfuge. Greeting him in the offhand way least likely to develop his suspicion, I told him that I had a great idea in connection with the Jeffrey case and that the clue to it lay in a little gold ball which Mrs. Jeffrey sometimes wore and upon which she set great store. So far I spoke the truth. It had been given her by some one—not Mr. Jeffrey—and I believed, though I did not know, that it contained a miniature portrait which it might be to our advantage to see.

I expected his lip to curl; but for a wonder it maintained its noncommittal aspect, though I was sure that I caught a slight, very slight, gleam of curiosity lighting up for a moment his calm, gray eye.

"You are on a fantastic trail," he sneered, and that was all.

But I had not expected more. I had merely wished to learn what place, if any, this filigree ball held in his own suspicions, and in case he had overlooked it, to jog his curiosity so that he would in some way betray its whereabouts.

That, for all its seeming inconsequence, it did hold some place in his mind was evident enough to those who knew him; but that it was within reach or obtainable by any ordinary means was not so plain. Indeed, I very soon became convinced that he, for one, had no idea where it was, or after the suggestive hint I had given him he would never have wasted a half-hour on me. What was I to do then? Tell my story to the major and depend on him to push the matter to its proper conclusion? "Not yet," whispered pride. "Durbin thinks you a fool. Wait till you can show your whole hand before calling attention to your cards." But it was hard not to betray my excitement and to act the fool they considered me when the boys twitted me about this famous golden charm and asked what great result had followed my night in the Moore house. But remembering that he who laughs last laughs best, and that the cause of mirth was not yet over between Durbin and myself, I was able to preserve an impassive exterior even when I came under the major\'s eye. I found myself amply repaid when one of the boys who had studiously avoided chaffing me dropped the following words in my ear:

"I don\'t know what your interest is in the small gold charm you were talking about, but you have done some good work in this case and I don\'t mind telling you what I know about it. That little gold ball has caused the police much trouble. It is on the list of effects found in the room where the candle was seen burning; but when all these petty belongings of Mrs. Jeffrey\'s were gathered up and carried back to her husband, this special one was not to be found amongst them. It was lost in transit, nor has it ever been seen since. And who do you think it was who called attention to this loss and demanded that the article be found? Not Mr. Jeffrey, who seems to lay little or no stress upon it, but the old man they call Uncle David. He who, to all appearance, possessed no interest in his niece\'s personal property, was on hand the moment these things were carried into her husband\'s house, with the express intention, it seems, of inquiring for this gold ball, which he declared to be a family heirloom. As such it belonged to him as the present holder of the property, and to him only. Attention being thus called to it, it was found to be missing, and as no one but the police seemed to be to blame for its loss the matter was hushed up and would have been regarded as too insignificant for comment, the trinket being intrinsically worthless, if Mr. Moore had not continued to make such a fuss about it. This ball, he declared, was worth as much to a Moore as all the rest of his property, which was bosh, you know; and the folly of these assertions and the depth of the passions he displayed whenever the subject was mentioned have made some of us question if he is the innocent inheritor he has tried to make himself out. At all events, I know for a certainty that the district attorney holds his name in reserve, if the grand jury fails to bring in an indictment against Miss Tuttle."

"The district attorney is wise," I remarked, and fell athinking.

Had this latent suspicion against Mr. Moore any solid foundation? Was he the guilty man? The memorandum I had come across in the book which had been lately pulled down from the library shelves showed that, notwithstanding his testimony to the contrary, he had been in that house close upon that fatal night, if not on the very night itself. It also showed his extreme interest in the traditions of the family. But did it show anything more? Had he interrupted his writing to finish his query in blood, and had one of his motives for this crime been the acquisition of this filigree ball? If so, why had he left it on the table upstairs? A candle had been lit in that room—could it have been by him in his search for this object? It would be a great relief to believe so. What was the reason then that my mind refused so emphatically to grasp this possibility and settle upon him as the murderer of Mrs. Jeffrey? I can not tell. I hated the man, and I likewise deeply distrusted him. But I could not, even after this revelation of his duplicity, connect him in my thoughts with absolute crime without a shock to my intuitions. Happily, my scruples were not shared by my colleagues. They had listed him. Here I felt my shoulder touched, and a newspaper was thrust into my hand by the man who had just addressed me.

"Look down the lost and found column," said he. "The third advertisement you will see there came from the district attorney\'s office; the next one was inserted by Mr. Moore himself."

I followed his pointing finer and read two descriptions of the filigree ball. The disproportion in the rewards offered was apparent. That promised by Uncle David was calculated to rouse any man\'s cupidity and should have resulted in the bauble\'s immediate return.

"He got ahead of the police that time," I laughed. "When did these advertisements appear?"

"During the days you were absent from Washington."

"And how sure are you that he did not get this jewel back?"

"Oh, we are sure. His continued anxiety and still active interest prove this, even if our surveillance had been less perfect."

"And the police have been equally unsuccessful?"

"Equally."

"After every effort?"

"Every."

"Who was the man who collected and carried out those things from the southwest chamber?"

He smiled.

"You see him," said he.

"It was you?"

"Myself."

"And you are sure this small ball was among them?"

"No. I only know that I have seen it somewhere, but that it wasn\'t among the articles I delivered to Mr. Jeffrey."

"How did you carry them?"

"In a hand-bag which I locked myself."

"Before leaving the southwest chamber?"

"Yes."

"Then it is still i............
