"But you've only got the thing upside down," cried her brother. And I must confess that a disagreeable feeling began to manifest itself in the pit of my stomach as he moved closer beside her and tried to reverse the necklace so that the clasp would stand a left-handed one.

He twisted and turned it fruitlessly for several moments.

"Isn't that the limit?" he finally murmured, sinking back in his chair and regarding me with puzzled eyes. The girl, too, was once more studying my face, as though my movement represented a form of uncouth jocularity which she could not quite comprehend.

"What's the answer, anyway?" asked the mystified youth.

But his bewilderment was as nothing compared to mine. I reached over for the string of pearls with the ruby clasp. I took them and turned them over and over in my hands, weakly, mutely, as though they themselves might in some way solve an enigma which seemed inscrutable. And I had to confess that the whole thing was too much for me. I was still looking down at that lustrous row of pearls, so appealing to the eye in their absolute and perfect graduation, when I heard the younger man at my side call my name aloud.

"Kerfoot!" he said, not exactly in alarm and not precisely in anxiety, yet with a newer note that made me look up sharply.

As I did so I was conscious of the figure so close behind me, so near my chair that even while I had already felt his presence there, I had for the moment taken him for my scrupulously attentive waiter. But as I turned about and looked up at this figure I saw that I was mistaken. My glance fell on a wide-shouldered and rather portly man with quiet and very deep-set gray eyes. What disturbed me even more than his presence there at my shoulder was the sense of power, of unparaded superiority, on that impassive yet undeniably intelligent face.

"I want to see you," he said, with an unemotional matter-of-factness that in another would have verged on insolence.

"About what?" I demanded, trying to match his impassivity with my own.

He nodded toward the necklace in my hand.
