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:
