After a frugal dinner the young people climbed the dills as far as Penhouet. The bay was surrounded on all sides by high rocks, behind which were hidden smaller rocks, covered with mosses, and mussels; and on the right the cliff hollowed out into a dark cave facing the land. This little beach, cheerful by day, grew mysterious with the fall of night. Esperance could point out Quiberon, outlined across the way between land and sky like a ribbon of light. The little lighthouse, high on the plateau above the farm, sent out its long lunar arms regularly to sweep the country and search the sea. CHAPTER XVII Esperance kept her word to Doctor Potain, and spent fifteen days stretched out in a cosy lounge chair. The particular part of the beach had been chosen by Maurice, for it was during this time of forced repose that he intended to do his cousin's portrait for the next Salon. In a little hollow of the hill, he settled the chair. A great tamarisk with feathery foliage of bright green formed a background. To the right was the sea, to the left a glowering mass of dark rocks. Jean and Genevieve took turns in reading aloud, and the picture was said to be progressing famously. During the first two weeks Esperance spent about five hours every day in the chair, but from the sixteenth day she only devoted one hour for posing, after lunch, and then she began to organize excursions to explore the country round about. One morning as the four young people were returning from a bicycle ride, they saw ahead of them the little brake on its return journey from Palais to the farm which Mme. Darbois had used on a shopping expedition with Marguerite. In the brake were two other persons--two men. The excursionists were still too far from the carriage to recognize the strangers. But Esperance, who was watching, stopped suddenly. Genevieve, who was behind her, almost rode into her, and had to jump lightly from her wheel. Maurice and Jean were some distance behind. She called to them. They were much concerned to find Esperance, with a pale face, clenching her hands on the handle-bar. "What is it, cousin, what ails you?" At first she did not speak at all, then her eyes lost their far-away look and she gazed at Jean. "I don't know," she said in a changed voice, "I think I had some hallucination come upon me." Then she pointed towards the distant brake which was approaching Penhouet at a great pace. "What did you see?" Maurice insisted. "You have had a dizzy feeling come over you? You must be careful." "Yes, perhaps so," she went on, shaking her head as if to rid it of some vague thoughts that were disturbing her brain, "perhaps so. But let us be quick, for one of the gentlemen was Doctor Potain." "Were there two men," asked Jean. "Yes, two." And she started off again at a great pace. Jean was dolefully perplexed. When they arrived at the farm they were quite breathless from their long ride. The philosopher was waiting for them at the door.
