The Cleaner absolutely blew me away, and Joe Victim is a follow up to that book. Sounds good to me :)
From the Blurb:
Joe Middleton has a lot on his plate, to say the least. Arrested for a whole slew of murders he says he can’t remember, Joe—a.k.a. the Christchurch Carver—has been in jail for the last year awaiting trial, charged with the task of convincing the psychiatrists interviewing him that he wasn’t of sound mind and can’t be blamed for what he did. And, incredibly, that’s the least of his worries.
