Mr. Grex of Monte Carlo by E. Phillips Oppenheim

Hunterleys remained in the hotel only long enough to change his straw hat for a cap, put on a long, light overcoat and take an ash stick from his wardrobe. He left the place by an unfrequented entrance and commenced at once to climb to the back part of the town. Once or twice he paused and looked around, to be sure that he was not followed. When he had arrived as far as the Hotel de Prince de Galles, he crossed the road. From here he walked very quickly and took three turns in rapid succession. Finally he pushed open a little gate and passed up a tiled walk which led between a little border of rose trees to a small white villa, covered with creepers. A slim, girlish figure came suddenly out from the porch and danced towards him with outstretched hands.

"At last! " she exclaimed. "At last! Tell me, my co-guardian, how you are going to excuse yourself?"
