A serial killer is terrorising Dublin.

Four murders. One pattern. And a message no one understands.

Newly appointed Detective Peter Alfson is thrown into a case already spiralling out of control. At every crime scene, the killer leaves behind the same calling card — a book… and a symbol that makes no sense.
Teaming up with convicted hacker Cassandra Roland, Alfson begins to uncover a trail that leads far deeper than a simple murder spree.

When a fifth body is found — and their only suspect falls apart — it becomes clear:

This isn’t random. This is planned.

As fear grips the city and tensions rise, the line between justice and revenge begins to blur. With time running out, Alfson must uncover the truth before Dublin tears itself apart — and before the killer’s endgame is complete.

Because some killers don’t just want to be caught…

They want to be understood.
