"But—" began Slattin.

"I will ring you up in less than half an hour," said Kâramanèh; and without further ceremony, she opened the door.

I still had my eyes glued to the aperture in the blind, when Smith began tugging at my arm.

"Down! you fool!" he hissed sharply; "if she sees us, all is lost!"

Realizing this, and none too soon, I turned, and rather clumsily followed my friend. I dislodged a piece of granite in my descent; but, fortunately Slattin had gone out into the hall and could not well have heard it.

We were crouching around an angle of the house, when a flood of light poured down the steps, and Kâramanèh rapidly descended. I had a glimpse of a dark-faced man who evidently had opened the door for her; then all my thoughts were centred upon that graceful figure receding from me in the direction of the avenue. She wore a loose cloak, and I saw this fluttering for a moment against the white gate-posts; then she was gone.

Yet Smith did not move. Detaining me with his hand he crouched there against a quick-set hedge; until, from a spot lower down the hill, we heard the start of the cab, which had been waiting. Twenty seconds elapsed, and from some other distant spot a second cab started.

"That's Weymouth!" snapped Smith. "With decent luck, we should know Fu-Manchu's hiding-place before Slattin tells us!"

"But—"

"Oh! as it happens he's apparently playing the game." In the half-light, Smith stared at me significantly. "Which makes it all the more important," he concluded, "that we should not rely upon his aid!"
