Who is the sinner and who is the saint?

Jamie Brooke is working as a private investigator in the London Borough of Southwark when the body of a priest is found in the ruins of Winchester Palace, his tattooed arms flayed, his mouth stuffed with feathers.

Jamie begins the hunt for the skin collector with the help of museum researcher, Blake Daniel, who is haunted by visions of a terrifying past.

As violence erupts, leaving a trail of bodies in its wake, Jamie and Blake must find the murderer before those they love are taken down in the chaos.
