Was Victoria really the assassin's target? Are those closest to the Crown hiding something? And who is the shadowy figure witnesses describe as having lifeless, coal-black eyes?Soon, Field's investigation exposes a shocking conspiracy in which the publication of Charles Darwin's controversial On the Origin of Species sets off a string of murders, arson, kidnapping, and the pursuit of a madman named the Chorister. As the investigation takes Field from the dangerous alleyways of London to the hallowed halls of Oxford, the list of possible conspirators grows, and the body count escalates. And as he edges closer to the Chorister, he uncovers dark secrets that were meant to remain forever hidden. Tim Mason has created a rousing page-turner that both Charles Dickens and Sir Arthur Conan Doyle would relish and envy.
