PERFECT KILLER by Robb T. White
 

Stylish, chilling and more than a little bit challenging, this American manhunt mixes a really remarkable serial murderer who has a penchant for peculiar philosophy with an intense, beleaguered FBI investigator. Superficially it owes a lot to Silence of The Lambs, but Perfect Killer stands apart as an enthralling novel in its own right. Jade Hui is a powerful female protagonist, beset but never beaten by personal and professional obstacles. She’s evenly matched against by weirdly compelling killer, Charles Wöissell, who’s one of the most scarily credible fictional psychopaths we’ve ever encountered. Gruesome in places, the story’s strength comes from the complexity of its characters.
