Accompanied by one of her female accomplices, Jenny joined the crowd at the entrance of a place of worship in the Old Jewry, where a popular divine was to preach, and observing a young gentleman with a diamond ring on his finger she held out her hand, which he kindly received in order to assist her. At this juncture she contrived to get possession of the ring without the knowledge of the owner, after which she slipped behind her companion, and heard the gentleman say, that, as there was no probability of gaining admittance, he would return. Upon his leaving the meeting he missed his ring, and mentioned his loss to the persons who were near him, adding that he suspected it to be stolen by a woman whom he had endeavoured to assist in the crowd; but as the thief was unknown she escaped. This proof of her dexterity was considered so remarkable that her associates determined to allow her an equal share of all their booties, even though she should not be present when they were obtained. In a short time after this exploit she procured a pair of false hands and arms to be made, and concealing her real ones under her clothes, she put something beneath her stays so as to make herself appear as if in a state of pregnancy, and repaired on a Sunday evening to the place of worship above-mentioned in a sedan chair, one of the gang going before to procure a seat for her among the genteeler part of the congregation, and another attending in the character of a footman. Jenny being seated between two elderly ladies, each of whom had a gold watch by her side, she conducted herself with great seeming devotion; but, the service being nearly concluded, she seized the opportunity, when the ladies were standing up, of stealing their watches, which she delivered to an accomplice in an adjoining pew. The devotions being ended, the congregation were preparing to depart, when the ladies discovered their loss, and a violent clamour ensued. One of the parties exclaimed "That her watch must have been taken either by the devil or the pregnant woman!" on which the other said, "She could vindicate the pregnant lady, whose hands she was sure had not been removed from her lap during the whole time of her being in the pew."
