"A spangle from a sequin dress," he muttered to himself; then, turning to Miss Grey, "Did any one wear such a dress last night?"

Helen Grey looked positively frightened. "Miss Hargrave!" she murmured, simply. "Oh, it cannot be—there must be some mistake!"

Just then we heard voices in the hall.

"But, Murray, I don't see why I can't see him," said one.

"What good will it do, Lewis?" returned the other, which I recognized as that of Doctor Murray.

"Fleming Lewis," whispered Miss Grey, taking a step out into the hallway.

A moment later Doctor Murray and Lewis had joined us.

I could see that there was some feeling between the two men, though what it was about I could not say. As Miss Grey introduced us, I glanced hastily out of the corner of my eye at Kennedy. Involuntarily his hand which held the telltale sequin had sought his waistcoat pocket, as though to hide it. Then I saw him check the action and deliberately examine the piece of tinsel between his thumb and forefinger.

Doctor Murray saw it, too, and his eyes were riveted on it, as though instantly he saw its significance.

"What do you think—Jack as sick as a dog, and robbed, too, and yet Murray says I oughtn't to see him!" complained Lewis, for the moment oblivious to the fact that all our eyes were riveted on the spangle between Kennedy's fingers. And then, slowly it seemed to dawn on him what it was. "Madeline's!" he exclaimed, quickly. "So Mina did tear it, after all, when she stepped on the train."
