Author Evangeline Holland tells the story of Adam Worth and of his most famous theft. To quote:
For a large part of the late 19th century, one man confounded, outwitted, and bemused the police forces of multiple continents: Adam Worth (1844-1902). So difficult was it to catch him red-handed, so wily were his swindles, and so brazen were his thefts that Scotland Yard called him the “Napoleon of Crime.” His greatest and most famous theft of all was that of Gainsborough’s portrait of Georgiana, the Duchess of Devonshire in 1876. Worth, who was born to Jewish parents in Cambridge, Massachusetts, worked his way up from a bounty jumper during the Civil War (bounty jumpers were those who joined the Army and then deserted with their enlistment bounties), to bank robber, to gambling saloon owner, and finally to jewel and art thief. With his dapper good looks and excellent manners, Worth even managed to infiltrate English high society for a brief period–though of course he used his position to rob his esteemed and flattered aristocratic friends.
