The miniseries is based on Liz Moore's 2020 novel of the same name, adapted for Peacock and announced in January 2024 with Nikki Toscano as showrunner.

The show was written by novelist Liz Moore herself alongside showrunner Nikki Toscano, who both also served as executive producers.

Amanda Seyfried was attached to the lead role of Mickey Fitzpatrick from the project's initial announcement in January 2024.

The supporting cast was assembled quickly in early 2024, with Nicholas Pinnock cast in February 2024, followed the same month by Ashleigh Cummings, Callum Vinson and John Doman, then Dash Mihok, Britne Oldford, Matthew Del Negro and Harriet Sansom Harris in March 2024.

To prepare for her role as a Philadelphia patrol officer, Amanda Seyfried took part in a ride-along with real Philadelphia police officers in January 2024.

Although the story is set in Philadelphia's Kensington neighborhood, the series was actually filmed in New York starting in March 2024.
