The rumbustious true story of the Victorian master thief who was the model for Conan Doyle's Moriarty, Sherlock Holmes' arch-rival. From the bestselling author of `Operation Mincemeat' and `Agent Zigzag'. Adam Worth was the greatest master criminal of Victorian times. Abjuring violence and setting himself up as a perfectly respectable gentleman, he became the ringleader for the largest criminal network in the world and the model for Conan Doyle's evil genius, Moriarty. At the height of his powers, he stole Gainsborough's famous portrait of Georgiana, Duchess of Devonshire, then the world's most valuable painting, from its London showroom. The duchess became his constant companion, the symbol and substance of his achievements. At the end of his career, he returned the painting, having gained nothing material from its theft. Worth's Sherlock Holmes was William Pinkerton, founder of America's first and greatest detective agency. Their parallel lives form the basis for this extraordinary book, which opens a window on the seedy Victorian underworld, wittily exposing society's hypocrisy and double standards in a storytelling tour de force.
