Slaughter Park (The Belltree Trilogy, 3)

Harry Belltree’s obsessive pursuit of justice has cost him everything―his job in homicide, his marriage and his newborn child. He has nothing left to lose, or so he thinks. Then his estranged wife disappears, leaving their baby daughter behind. The police think Jenny has murdered a man. Harry thinks she’s in danger. When severed limbs are found dangling from the branches of trees in a suburban park, Harry’s former colleagues are pulled off Jenny’s case. It’s up to Harry to track his missing wife down on his own. And to lay bare, at last, the extraordinary conspiracy that led to his parents’ murder.
