While the husband exercised his reflection in this manner, his innocent mate did not allow the powers of her imagination to rest in idleness and sloth. Her observations touching the loss of the chain were such as a suspicious woman, biassed by hatred and envy, would naturally make. To her it seemed highly improbable, that a thing of such value, so carefully deposited, should vanish without the connivance of its keeper, and without much expense of conjecture, divined the true manner in which it was conveyed. The sole difficulty that occurred in the researches of her sagacity, was to know the gallant who had been favoured with such a pledge of Wilhelmina's affection; for, as the reader will easily imagine, she never dreamed of viewing Ferdinand in that odious perspective. In order to satisfy her curiosity, discover this happy favourite, and be revenged on her petulant rival, she prevailed upon the jeweller to employ a scout, who should watch all night upon the stair, without the knowledge of any other person in the family, alleging, that in all likelihood, the housemaid gave private admittance to some lover who was the author of all the losses they had lately suffered, and that they might possibly detect him in his nocturnal adventures; and observing that it would be imprudent to intimate their design to Wilhelmina, lest, through the heedlessness and indiscretion of youth, she might chance to divulge the secret, so as to frustrate their aim. A Swiss, in whose honesty the German could confide, being hired for this purpose, was posted in a dark corner of the staircase, within a few paces of the door, which he was directed to watch, and actually stood sentinel three nights, without perceiving the least object of suspicion; but, on the fourth, the evil stars of our adventurer conducted him to the spot, on his voyage to the apartment of his Dulcinea, with whom he had preconcerted the assignation. Having made the signal, which consisted of two gentle taps on her door, he was immediately admitted; and the Swiss no sooner saw him fairly housed, than he crept softly to the other door, that was left open for the purpose, and gave immediate intimation of what he had perceived. This intelligence, however, he could not convey so secretly, but the lovers, who were always vigilant upon these occasions, overheard a sort of commotion in the jeweller's chamber, the cause of which their apprehension was ingenious enough to comprehend.
