About this book

What if the man welcomed into the drawing room hides a life of deception and murder?

In A Servant of Satan, Louis Berard follows Prado, a criminal said to move among respectable people while concealing deceit and violence. A false name, an invented past and borrowed rank help him win trust. In a world where manners can pass for proof, charm becomes a tool for opening doors.

The story reaches across three continents, following lies, pursuit and the law that slowly closes in. Drawing rooms, clubs and fashionable resorts give Prado cover, while borders offer fresh strangers and distance from those seeking him. Berard presents a popular true crime account that carries the reader from the impostor’s deceptions toward the courtroom.

  • The tools of deception Follow the false names and invented past that make other people’s trust so useful.

  • A pursuit across borders See how distance and gaps between police forces give a clever criminal room to move.
