Harlow's Monkey, Ludovic Lancien

Relieved of his duties as commander of the Parisian judicial police, Lieutenant Lucas Dorinel experiences his exile in Brest as a slow death. Until an obscure message—"The Beasts will be sacrificed"—reminds him of the true horror of death.
For the message leads him to a corpse. Savagely mutilated. That of a man incarcerated eight years earlier for the murder of a child.
By addressing him directly, the killer awakens in Lucas both his police instinct and his violence. The murderer and he are cut from the same cloth. Ready to fight evil with evil.
And to hunt down the Beasts wherever they hide.
