“I’ll tell you presently, Petrie. Did you see him?”

“I did, and I can’t make out what he is doing. He seems to have remained standing at the gate for some reason.”

“He has seen it!” snapped Smith. “Watch those elms.”

His hand remained upon my arm, gripping it nervously. Shall I say that I was surprised? I can say it with truth. But I shall add that I was thrilled, eerily; for this subdued excitement and alert watching of Smith could only mean one thing:

Fu-Manchu!

And that was enough to set me watching as keenly as he; to set me listening; not only for sounds outside the house but for sounds within. Doubts, suspicions, dreads, heaped themselves up in my mind. Why was Forsyth standing there at the gate? I had never seen him before, to my knowledge, yet there was something oddly reminiscent about the man. Could it be that his visit formed part of a plot? Yet his wound had been genuine enough. Thus my mind worked, feverishly; such was the effect of an unspoken thought—Fu-Manchu.

Nayland Smith’s grip tightened on my arm.

“There it is again, Petrie!” he whispered.

“Look, look!”

His words were wholly unnecessary. I, too, had seen it; a wonderful and uncanny sight. Out of the darkness under the elms, low down upon the ground, grew a vaporous blue light. It flared up, elfinish, then began to ascend. Like an igneous phantom, a witch flame, it rose, high—higher—higher, to what I adjudged to be some twelve feet or more from the ground. Then, high in the air, it died away again as it had come!
