Broadchurch + V.I. Warshawski

It's like Warshawski because she's a tough customer, often acts like a guy, drinks, often surly, picks up guys and sleeps with them, and has a generally messed up existence.

It's like Broadchurch because it's not just the cops and crooks, but the participation of the whole town, including kids, and everyone knows everyone else, and just like in Broadchurch, people know things, but never tell what they know unless it's completely dragged out of them.
