Meanwhile, Kennedy had enlisted the aid of two detectives and was scouring the city for a trace of Bennett or the taxicab in which he had fled.

Somehow, Kennedy suspected, instinctively, that Long Sin might give a clue to Bennett’s whereabouts, and a few moments later, we were all on our way in a car to Long Sin’s house.

Though we did not know it, Long Sin, at the moment when Kennedy knocked at his door, was feeling in his inside pocket to see that the map he had taken from Bennett was perfectly safe.  Finding that he had it, he smiled with his peculiar oriental guile.  Then he opened the door, and stood for a moment, silent.

“Where is Bennett?” demanded Kennedy.

Long Sin eyed us all, then with a placid smile, said, “Follow me.  I will show you.”

He opened a trap door, and we climbed down after Craig, entering a subterranean chamber, led by Long Sin.

There was Bennett seated rigidly in the chair beside the table from which the vials and cups, about which we then knew nothing, had been removed.

“How did it happen?” asked Kennedy.

“He came here,” replied Long Sin, with a wave of his hand, “and before I could stop him he did away with himself.”

In dumb show, the Chinaman indicated that Bennett had taken poison.

“Well, we’ve got him,” mused Kennedy, shaking his head sadly, adding, after a pause, “but he is dead.”

Elaine, who had followed us down, covered her eyes with her hands, and was sobbing convulsively.  I thought she would faint, but Kennedy led her gently away into an upper room.

As he placed her in an easy chair, he bent over her, soothingly.

“Did you—­did you—­really—­love him?” he asked in a low tone, nodding in the direction from which he had led her.

Still shuddering, and with an eager look at Kennedy, Elaine shook her beautiful head.

Then, slowly rising to her feet, she looked at Craig appealingly.  For a moment he looked down into her two great lakes of eyes.

“Forgive me,” murmured Elaine, holding out her hand.  Then she added in a voice tense with emotion, “Thank you for saving me.”

Kennedy took her hand.  For a moment he held it.  Then he drew her towards him, unresisting.

THE END
