Easy Meat 
(Resnick 8)

Why would a fifteen-year-old boy commit suicide? Mind you, who cares when he»s a no-good kid on trial for bludgeoning an elderly couple to death?
But when the senior investigating officer is then found brutally murdered, DI Charlie Resnick is put on the case, and uncovers some sinister and startling revelations.
It also brings Resnick into contact with Hannah Campbell, with whom he finds himself falling unexpectedly and awkwardly in love.
