"The Comte Paul d'Esneux."

"Is he French?" I asked, at the same time inquiring his description.

From the latter, as the detective gave it to me, I at once knew that the Comte d'Esneux and Jules Jeanjean were one and the same.

"Non, Monsieur," replied the man. "He is a great Belgian financier. He comes here at frequent intervals, and carries on his experiments with wireless telegraphy. It is said that he has made several discoveries in wireless telephony, hence the Government have given him permission to establish a station with as great a power as that at Oran."

"And he is often experimenting?"

"Constantly. It is said that he can actually transmit messages to Paris and England. Last year, when the station at Oran was injured by fire, the Government operators came here, took his instruments over and worked them. The installation is, I believe, most up-to-date."

"Bien!" I said. "Then let us go up there, and see this Comte d'Esneux."

And together we entered a ramshackle fiacre in The Place, and drove away out by the city gate to the white, dusty high-road, along which many white-robed Arabs and a few Europeans were trudging in the burning glare of the African sun.

When I had mentioned the Count as the person whom I wished to see, I noticed that the detective hesitated, and, with a strange look, regarded me with some apprehension.

Did he suspect? Was he suspicious of the truth concerning the actual identity of the wealthy Belgian financier who dabbled in wireless?
