Cassian – The Pain of God

Introduction

With *Cassian – The Pain of God*, musician, composer, and author Udo Sailer will publish an extraordinary Vatican thriller in 2026.

Deep within the Vatican, a series of disturbing crimes unfolds, entangling a small group in a struggle for truth, faith, and power. 

Set against a backdrop of church structures, repressed guilt, and fanatical belief in salvation, this novel explores the abuse of religious power, moral transgressions, and the destructive power of silence.

Description

This is the story of Cassian Marchese.

He was a priest, a student at a Shaolin monastery, a father, and a murderer. Anyone who met him saw a calm and disciplined man—someone who rarely raised his voice and showed his emotions even more rarely. Many considered him strong.

But strength and healing are not the same thing.

Even as a child, Cassian had learned to hide his pain. Later, he learned to control it. What no one taught him was how to live with it. Guilt turned into conviction. Conviction turned into certainty. And from that certainty arose a ritual that claimed the lives of more and more people.

Cassian believed he had to uncover the truth. He believed that redemption required sacrifice. For years, he considered himself an instrument of good, even though his hands had long been stained with blood.

This isn't a story about a hero. Nor is it about a monster.

It is the story of a priest who wanted to take God's place.

Target Audience Note

The novel is aimed at readers of Vatican thrillers and psychological suspense novels. It will be of particular interest to those who are interested in issues of guilt, faith, religious fanaticism, abuse of power within the Church, and moral responsibility.
