The London Guide for Strangers was first published in 1819, under the title (or blurb) of The London Guide, and Stranger's Safeguard against the Cheats, Swindlers and Pickpockets that abound within the Bills of Mortality; forming a picture of London, as regards active life, collected from the verbal communications of William Perry, and others. To which is added, a glossary of cant terms. By A Gentleman, who has made the Police of the Metropolis, an object of enquiry for twenty-two years. It really needs no further introduction, except to say, that the methods used by criminals on the unwary had not changed much in the two centuries since Green described them in The Complete Cony-Catching; and probably have not changed much in our day, another two centuries later.
