The Jailer

A Department 89 Origin Thriller of Prison Corruption, Power, and Relentless Justice

You can’t buy your way out if the man holding the keys won’t bend

Max Amsel is a prison officer who believes in rules, containment, and consequences. When Germany’s most dangerous crime boss, Karl Vogt, escapes custody with inside help, Amsel refuses to play along—or look the other way. His reward is betrayal, an attempted murder, and being marked as the problem by the very system he served.

As corruption inside the prison service and the Ministry begins to surface, Amsel goes on the offensive against a network built on bribes and fear. But the closer Amsel gets to the truth, the clearer it becomes that powerful people would rather kill loose ends than face accountability.

The Jailer is the brutal origin story of a man who cannot be bought, cannot be intimidated, and will not unlock the door—no matter who’s screaming on the other side.
