Anyone got recommendations for serial killer/type books?

[Shonajay]

I've read Cornwall, reichs, Connelly, deaver, lee child, all of the usual but am running out.

Richard montanari - he's done a series of books. I enjoyed those. Set in Philadelphia.
The Logan Macrae books by Stuart Macbride are also very good.

Here are the ones I have recently read that are gritty -
