of London. Little is known of Wild's first two years in London, but he was arrested for debt in March 1710 and sent to Wood Street Compter, one of the debtor's prisons in the City of London. The prisons were notoriously corrupt, with gaolers demanding a bribe, or "garnish", for any minor comfort. Wild became popular, running errands for the gaolers and eventually earning enough to repay his original debts and the cost of being imprisoned, and even lend money to other prisoners. He received "the liberty of the gate", meaning that he was allowed out at night to aid in the arrest of thieves. There, he met one Mary Milliner (or Mary Mollineaux), a prostitute who began to teach Wild criminal ways and, according to Daniel Defoe, "brought him into her own gang, whether of thieves or whores, or of both, is not much material". Wild was also introduced to a wide range of London's criminal underclass. With his new skills and contacts, Wild was released in 1712 under an Act of Parliament passed earlier that year for the relief of insolvent debtors. Upon release, Wild began to live with Milliner as her husband in Lewkenor's Land (now Macklin Street) in Covent Garden, despite both of them having prior marriages. Wild apparently served as Milliner's tough when she went night-walking. Soon Wild was thoroughly acquainted with the underworld, with both its methods and its inhabitants. At some point during this period, Milliner had begun to act as something of a madam to other prostitutes, and Wild as a fence, or receiver of stolen goods. He began, slowly at first, to dispose of stolen goods and to pay bribes to get thieves out of prison. Wild later parted with Milliner, cutting off her ear to mark her as a prostitute. Coming into his own Crime had risen dramatically in London beginning in 1680, and property crime, in particular, rose sharply as London grew in importance as a commercial hub. In 1712 Charles Hitchen, Wild's forerunner and future rival as thief-taker, said that he personally knew 2,000 people in London who made their living solely by theft. In 1711, Hitchen had obtained public office as the City's Under Marshal, effectively its top policeman, paying £700 (£ in ) for the appointment. He abused his office, however, by practising extortion on an extravagant scale, both from thieves and from their potential victims.
