The room, panelled in cedar-wood, was Moorish in character, the light filtering in through long windows of stained glass. Around the vaulted ceiling was a symmetrical device in Arabesque in gold, red and blue, while about the place were soft Moorish divans and silken cushions, with rich rugs on the floor, and a heavy brass arabesque lamp suspended from the centre of the ornamented ceiling. The place was full of the subtlest perfume of burning pastilles, and, in a cabinet, I noted a collection of rare Arab gold and silver jewellery.

And this was the home of the motor-bandit of the Forest of Fontainebleau—the man who had shot dead the Paris jeweller, Benoy, with as little compunction as he killed a fly.

I strode around the room, bewildered by its Arabian Nights aspect. Truly Jules Jeanjean lived in a style befitting an Eastern Prince.

"Hush!" I exclaimed, and we both listened to a loud crackling. "That," I said, "is the sound of wireless telegraphy. A message is being sent out across the sea."

Jeanjean was evidently in a room in the vicinity.

Suddenly the noise ceased. The door-keeper, who had not asked our names, had evidently sent in the message that two strangers desired to see his master.

But it was only a pause, for in a few seconds the message was resumed. I could easily distinguish the long and short cracks of the spark across the gap, as the electric waves were sent into the ether over the Mediterranean to Europe.

I happen to know the Continental Morse code, for I had dabbled in wireless telegraphy two years before. So I stood with strained ears trying to decipher the tapped-out message. I heard that it was directed to some station the call-letters of which were "B. X." But the message was a mere jumble of letters and numerals of some pre-arranged code.

I listened attentively till I heard the rapid short sound followed by four long sounds, and another short one, which indicated the conclusion of the message.
