In an episode that predated the Watergate break-in by 100 years, thieves broke into the New York City Comptroller’s office on September 10, 1871, and stole records that threatened to end the corrupt reign of Boss Tweed over the Tammany Hall political machine. Fittingly, the thieves used a symbol of the Tweed Ring – a diamond – to cut a hole in the glass office door. This is the story of Boss Tweed and the diamonds of Tammany Hall.
