Corpses whose bodies dissolve in a very short time and a client with an unbelievable history.
What are the goals of a union of former Eastern Bloc agents? And what is hidden behind the accident in the Austrian Alps?
The chief inspector Marlies Bender and the private investigator Alexander Buschbeck suddenly find their way into the thicket of secret service operations.
Seemingly coincidental events follow a sophisticated concept, a monstrous scheme of deadly vigilante justice.

The first case of private investigator Alexander Buschbeck.

Cruel deaths occur in Dresden.

Everything speaks for suicide. No leads, no suspects, no motives. The investigation threatens to come to nothing until Chief Inspector Karl Löwenberg sets the profiler Penny Lebowski on the cases. A hitherto undreamed-of connection between the fatalities comes to light.

A merciless race against time begins, or Dresden is doomed.

A student, brutally murdered in her sleep.

Reason enough to put the team around the profiler Gloria Siegel on this case. Supported by the mysterious Alexander Buschbeck, who is said to have clairvoyant abilities, they quickly find a suspect in the brother of the dead.

But the case does not seem so clear. In addition, someone is apparently after the profiler.

Hotel guest mutilated and set on fire!

On Profilerin Dr. Gloria Siegel and her young team are waiting for a new case.

A serial killer is at work who has already struck fifteen times - and does not stop.

While the youth team is busy hypothesizing, the mysterious one leaves Alexander Buschbeck approaches the case from a completely different angle - and comes closer to the perpetrator than any of her victims.

A serial killer with highly idiosyncratic preferences is up to mischief in Dresden.

A clear task for the attractive case analyst Dr. Gloria Siegel.

However, the bureaucracy denies her an experienced analysis team, whereupon she starts a youth project.

How will the four newcomers fare in their first case? Should you accept the help of the mysterious Alexander Buschbeck?

Is he perhaps the murderer himself?
