Frederick had never lied before, but he was lying now. Up to this time he had always confessed his faults to his mother. She had been the confidant of his every thought, but the mere idea of confessing or of allowing her to discover the bitter feelings which his visit to the Château de Pont Brillant had excited in his breast filled him with shame and dismay. In fact, he would rather have died than confess that he was enduring the torments of envy; so, placed upon his guard by Madame Bastien's lively solicitude, he devoted all his powers of mind and strength of will to conceal the wound that was beginning to rankle in his soul, but it is almost certain that his attempts to deceive his mother's tender sagacity would have proved futile had that mother not been at the same time reassured and deceived by Doctor Dufour. "Don't be alarmed," the physician said to her when she, in all sincerity, consulted him on the subject of her fears. "At the time of puberty, an entire change often takes place in a youth's character. The gayest and most demonstrative often become the most gloomy and taciturn. They experience the most unreasonable melancholy, the most acute anxiety. They give way to fits of profound depression, and feel an intense longing for solitude. So do not be alarmed, and above all give no sign of having noticed this change in your son. This almost inevitable crisis will be over in a few months, and you will then see Frederick himself again. He will have a different voice, that is all." Doctor Dufour's mistake was the more excusable as the symptoms which so alarmed Madame Bastien strongly resembled those which are often noticed in youths at that age; so Madame Bastien accepted this explanation, as she could not divine the real cause of this change in Frederick. This change had not manifested itself immediately after the visit to the chateau. It had, on the contrary, taken place gradually, almost imperceptibly, in fact, so that more than a month had elapsed before Madame Bastien really began to feel uneasy, hence it did not seem at all probable that there could be any connection between the visit to the château and Frederick's melancholy. Besides, how could Madame Bastien suppose that this youth reared by her--a youth who had always seemed of so noble and generous a character--could know envy? So, reassured by Doctor Dufour, Madame Bastien, though she watched the different phases of her son's condition, forced herself to conceal the sadness she often felt on seeing him so changed, and awaited his recovery with resignation. At first Frederick had tried to find some diversion in study, but soon study became impossible; his mind was elsewhere. Then he said to himself:
