"Very good."

Almost holding my breath, so intense was my excitement, I waited whilst Miguel went to bring the Hindu. Suddenly a new voice spoke—that of the Hindu.

"Chunda Lal speaks," it said.

I clenched by teeth; I knew that I must not miss a syllable.

"Scorpion" replied … in voluble Hindustani—a language of which I know less than a dozen words!

CHAPTER II

CONCERNING THE GRAND DUKE

Although I had met with an unforeseen check, I had nevertheless learned three things. I had learned that Miguel the quadroon was possibly in league with the Hindu; that the Hindu was called Chunda Lal; and that Chunda Lal received messages, probably instructions, from a third party who announced his presence by the word "Scorpion."

One of my fellows, of course, had been in the cafe all the evening, and from him I obtained confirmation of the fact that it had been the Hindu who had been summoned to the telephone and whom I had heard speaking. Instant upon the man at the cafe replacing the telephone and disconnecting, I called up the exchange. They had been warned and were in readiness.

"From what subscriber did that call come?" I demanded.
