I watched Mademoiselle as she passed out of the station to a little restaurant where she had a frugal meal. Then she returned and took a ticket back to her home in Castelsarrasin.

Rivero now had his hands full. Not only had he identified in the respectable commercial traveller, Charles Rabel, the notorious assassin Despujol, but he had also quite accidentally come across Sanz the motor-bandit, who of late had terrorized the south of Spain, and whose daring depredations were upon everyone’s lips. Mademoiselle seemed to be a friend of both men!

I returned to my hotel close by, and ate my déjeuner alone. My position was a very unenviable one, for I feared to go over into the town lest I should come face to face with the man who had so cunningly made an attempt upon me as the hireling of Oswald De Gex.

But my thoughts were ever of my beloved, the girl who was the victim of some foul plot into which I, too, had been drawn—a mystery which I was devoting my whole life to solve.

At five o’clock that evening I received a telegram from Harry in Madrid, telling me that all was quiet, and “our friend”—meaning De Gex—never went out.

To this I replied in a cryptic way that our suspicions had been verified, and that the person of whom we were in search we had discovered. We were only now waiting for the appointment to be kept at the Hôtel de Luxembourg at Nîmes.

Next day passed uneventfully. In order to kill time I took train to the quaint little town of Moissac, an ancient little place on the Tarn about twenty-five kilomètres distant, and there spent the hours wandering about the countryside which is so famed for its grapes in autumn. I did not return to Montauban till after seven, and while I sat at dinner the waiter handed me another telegram. It was from Rivero, and having been sent from Lyons, read: “All well. Just returning to Montauban.”

Later, I busied myself with time-tables and found that he would be due to arrive about six o’clock on the following morning. Therefore I possessed myself in patience, and I was still in bed when in the morning he entered my room.

“Well?” he exclaimed in French, as he sank wearily into a chair. “I’ve had a swift and weary journey. Sanz has been alarmed by the girl. Why, I cannot tell. Did she go to see Despujol?”

“No,” I replied. “She didn’t see him, but went straight home.”
