Sometimes the monsters aren't paranormal.

Sir Malcolm Bradbury, Knight of the Realm and a man whose ambitious greed and avarice lets him destroy lives, is slowly taking control of the City of Plymouth leaving the dead bodies of his victims in his wake.
The Plymouth Grey, the secret group protecting Plymouth against paranormal threats, know that they are the only people able to put a stop to his reign of terror. But how can they do so without calling unwanted attention upon themselves?
Their plans take shape when a cargo ship arrives back in Plymouth, and its captain becomes a vital piece in the strangest horse race ever witnessed by Queen Victoria at the Chelson Meadow racecourse.

But have the Grey done enough to defeat a human monster?
