“To the devil with your druggist—and with you, too, Borg!” spat the Scorpion leader. “You may think you’re funny, but I do not. Lotus! Bring this fool out to the door in three minutes, or it will be the worse for you both. I’ll wait for you just that long!”

Turning on his heel, the bulky Oriental stalked out of the alcove. Following slowly with Lotus, Don saw Cho-San halt and stare at the figure of “Penny” who had just appeared in the lobby. Evidently Red had made record time for a valet, after getting the head-waiter’s phone call.

With a murmured excuse to Lotus, Don stepped forward to meet his manservant at a point just out of earshot.

“Listen, Red!” he whispered, taking the small bottle Pennington had brought. “I’m going for a ride with Cho-San and the Lotus in about two minutes. Follow us in another car, but watch your step. That’s all for now!”

Slipping into his topcoat, he sauntered back to the girl.

“Come, little Lotus!” he said banteringly. “We musn’t keep your guardian waiting. It’s bad for the jolly old dragon’s disposition. By the way, where are the comrades’ headquarters he spoke of. I suppose I must have been there countless times, but it’s all foggy in my head now.”

Sudden fear showed again in the look Lotus gave him.

“I—I wonder, André,” she said in a strained tone, “if Cho-San may not be partly right about the change in you. It doesn’t seem possible you could have forgotten so many things! I wonder if you are not just playing a part, for some strange purpose of your own!”

There was no time for Don to think up a reply, as they were already passing through the outer door. Just across the sidewalk the huge figure of Cho-San bulked beside a waiting car.

Once inside the limousine, Don found himself in no mood for further self-explanations. More and more it was being impressed upon him that the job he had undertaken was beset with risks. So far he had been able to dodge open failure; but this fact failed to set his mind at ease.
