Catherine “Cat” Chandler is a smart, no-nonsense homicide detective, haunted by her own tragic past. When she was a teenager, Cat witnessed the murder of her mother and would have been killed too, but someone – or something – saved her. No one has ever believed her, but she knows it wasn’t an animal that saved her life…though it was strange and terrifying, it was human.
As season three begins, Cat and Vincent are able to focus on their love, finally free from Muirfield, manhunts and beasts. However, that love will be tested as new and more dangerous threats await. When they learn that innocent victims are being used to test the boundaries of the impossible, Cat and Vincent will uncover a deeper conspiracy, one which Vincent can fight only by turning to the beast he carries within. But unleashing the beast will risk Vincent’s life – along with his and Cat’s love – as they struggle to build a normal life together.
