A deadly new drug is on
the streets and analysis shows it is grown underground. Catherine informs Father and Vincent of the
findings and also mentions that the supplier only accepts gold coins in
payment. Father seeks out John Pater,
aka Paracelsus, a former tunnel leader banished many years ago. Paracelsus admits his involvement and
threatens to reveal the secret of the tunnels if they interfere. Catherine loses a friend and fellow
investigator who is stabbed by Paracelsus while trying to stop him. Vincent
attempts to stop Paracelsus from going Above again but is exposed to the
drug. He loses himself in its effects
and only Catherine is able to calm him.
When he recovers, he goes to confront Paracelsus. A struggle ensues and a fire is accidentally
started. Vincent escapes the blaze but
Paracelsus refuses to leave his gold and walks into the burning chamber.
