Jack now worked as a journeyman carpenter, with a view to the easier commission of robbery; and being employed to assist in repairing the house of a gentleman in May Fair, he took an opportunity of carrying off a sum of money, a quantity of plate, some gold rings, and four suits of clothes. Not long after this Edgeworth Bess was apprehended, and lodged in the round-house of the parish of St. Giles's, where Sheppard went to visit her; but the beadle refusing to admit him, he knocked him down, broke open the door, and carried her off in triumph; an exploit which acquired him a high degree of credit among his companions. Tom Sheppard being now as deep in crime as his brother, he prevailed on Jack to lend him forty shillings, and take him as a partner in his robberies. The first act they committed in concert was the robbing of a public-house in Southwark, whence they carried off some money and wearing apparel; but Jack permitted his brother to reap the whole advantage of this booty. Not long after this, in conjunction with Edgeworth Bess, they broke open the shop of Mrs. Cook, a linen-draper in Clare Market, and carried off goods to the value of 55_l._; and in less than a fortnight afterwards, they stole some articles from the house of Mr. Phillips in Drury Lane. Tom Sheppard going to sell some of the goods stolen at Mrs. Cook's, was apprehended, and committed to Newgate, when, in the hope of being admitted an evidence, he impeached his brother and Bess; but they were sought for in vain. At length James Sykes, otherwise called Hell-and-Fury, one of Sheppard's companions, meeting with him in St. Giles's, enticed him into a public-house, in the hope of receiving a reward for apprehending him; and while they were drinking Sykes sent for a constable, who took Jack into custody, and carried him before a magistrate. After a short examination, he was sent to St. Giles's round-house; but he broke through the roof of that place and made his escape in the night.
