The Christ Emerald

A double murder in the Vatican shocks the world. Heinrich Rosin, Colonel of the Swiss Guard, and his wife Juliette, are found dead in their home.

In his investigation into the true circumstances of the murder, guard adjutant Alexander Rosin, the victim's nephew, works with the young Roman journalist Elena Vida to delve deep into the Vatican's power structure. A secret society called the 'Circle of Twelve' and a forgotten Renaissance manuscript lead the pair to a centuries-old plot.
