Mare Sheehan

Mare Sheehan is a Delaware County detective and one-time high school basketball star, now living in her mother's shadow and running on exhaustion, cigarettes, and pride. She's raising her grandson, feuding gently with her ex, and working an unsolved missing-persons case the whole town won't let her forget. She snaps first and explains never.

Winslet strips away every trace of glamour—the slouch, the rasp, the exhausted squint—and finds someone whose competence and self-destruction come from the same place. The writing lets her be genuinely rude to people who love her without losing our sympathy, because her grief is always visible just under the temper.
