She now saw the necessity of subduing all appearance of reserve towards Adeline; and though her art could not conquer the prejudices of passion, it taught her to assume, with tolerable success, the aspect of kindness. Adeline was deceived, and was again at peace. Indeed, confidence in the sincerity and goodness of others was her weakness. But the pangs of stifled jealousy struck deeper to the heart of Madame La Motte, and she resolved, at all events, to obtain some certainty upon the subject of her suspicions.
She now condescended to a meanness which she had before despised, and ordered Peter to watch the steps of his master, in order to discover, if possible, the place of his visitation! So much did passion win upon her judgment, by time and indulgence, that she sometimes ventured even to doubt the integrity of Adeline, and afterwards proceeded to believe it possible that the object of La Motte's rambles might be an assignation with her. What suggested this conjecture was, that Adeline frequently took long walks alone in the forest, and sometimes was absent from the abbey for many hours. This circumstance, which Madame La Motte had at first attributed to Adeline's fondness for the picturesque beauties of nature, now operated forcibly upon her imagination, and she could view it in no other light, than as affording an opportunity for secret conversation with her husband.
Peter obeyed the orders of his mistress with alacrity, for they were warmly seconded by his own curiosity. All his endeavours were, however, fruitless; he never dared to follow La Motte near enough to observe the place of his last retreat. Her impatience thus heightened by delay, and her passion stimulated by difficulty, Madame La Motte now resolved to apply to her husband for an explanation of his conduct.
After some consideration concerning the manner most likely to succeed with him, she went to La Motte; but when she entered the room where he sat, forgetting all her concerted address, she fell at his feet, and was for some moments lost in tears. Surprised at her attitude and distress, he inquired the occasion of it, and was answered, that it was caused by his own conduct. My conduct! What part of it, pray? inquired he.
