The Third Halstead
A One Chicago Story (Not Entirely Canon)
Before she wore a badge, she was a nurse in a nursing home, working quiet shifts, caring for people the world forgot.
Becoming a cop came later, and even now, at twenty-seven, the youngest Halstead isn't sure she belongs in Chicago PD at all.
Pulled from the academy early by Alvin Olinsky and placed in Intelligence alongside Adam Ruzek, she's given a chance she doesn't think she earned. Surrounded by legends, carrying the Halstead name, and haunted by self-doubt, she's convinced she's only here because of who her brothers are.
She knows everyone in One Chicago.
Molly's feels like home.
But belonging is another matter entirely.
Content note: This story contains mature themes, including violence and child endangerment. No explicit sexual content.
Author's Note:
This story is not fully canon and may differ from the show.
It's about insecurity, second chances, and learning to believe you deserve the badge you wear.
This is my original fanfiction based on the One Chicago universe. English is not my first language, so I use writing assistance to help with wording and flow. All characters, plot points, and ideas are mine.
