"Indeed!" he rapped. "Why did you not tell me at the time?"

"I don't know."

My friend eyed me sharply.

"I noticed you seemed like a man intoxicated all the way from the shop," said he. "I attributed it to some aftermath of hashish. But no. Kathulos is undoubtedly a masterful disciple of Mesmer—his power over venomous reptiles shows that, and I am beginning to believe it is the real source of his power over humans.

"Somehow, the Master caught you off your guard in that shop and partly asserted his dominance over your mind. From what hidden nook he sent his thought waves to shatter your brain, I do not know, but Kathulos was somewhere in that shop, I am sure."

"He was. He was in the mummy-case."

"The mummy-case!" Gordon exclaimed rather impatiently. "That is impossible! The mummy quite filled it and not even such a thin being as the Master could have found room there."

I shrugged my shoulders, unable to argue the point but somehow sure of the truth of my statement.

"Kamonos," Gordon continued, "doubtless is not a member of the inner circle and does not know of your change of allegiance. Seeing the mark of the scorpion, he undoubtedly supposed you to be a spy of the Master's. The whole thing may be a plot to ensnare us, but I feel that the man was sincere—Soho 48 can be nothing less than the Scorpion's new rendezvous."

I too felt that Gordon was right, though a suspicion lurked in my mind.
