To be honest I was leery about another Darian Richards book being so completely over the utterly mad serial killer thing. But this is different and I'm finding it very hard to put down.
From the Blurb:
Darian Richards is an ex-cop, a good one. He did whatever it took to solve a crime and stop the bad guy. Whatever it took! But after sixteen years as the head of Victoria's Homicide Squad, he'd had enough of promising victims' families he'd find the answers they needed. He had to walk away to save his sanity.
