City of Vice

A break-in at a sugar merchant's Mayfair home brings the Bow Street Runners into conflict with their patron, Lord Newcastle. He reminds the Fielding brothers that their prime duty is to protect the property of the rich and yet the number of burglaries has increased under their new police force. Determined to prove him wrong, the brothers search for the Irish suspects in the shanty towns of Covent Garden, known as the Seven Dials.

Tom Jones, an infamous gang leader, is broken out of jail by his Irish gang, who maim several prison guards along the way. This high-profile jailbreak questions the authority of the Bow Street Runners and risks making Lord Newcastle look very foolish for supporting them. The Runners travel to the Seven Dials to re-arrest Jones. With Lord Newcastle reviewing the Runners' government allowance, Henry Fielding accompanies them to make sure Jones is apprehended.

Henry looks back on the struggle to fund the Bow Street Runners in the first place, and reflects on how close London came to not having a police force at all… As the new magistrates of Westminster, novelist Henry Fielding and his blind half-brother John want to set up a police force to tackle London's soaring crime epidemic. They find a potential patron in Lord Newcastle, the Prime Minister's brother, but he is unsure of such a force's merits. With the help of Saunders Welch, the High Constable of Holborn, the brothers set out to show Newcastle they can rid the streets of the violent criminal gangs.
