One afternoon, in the middle of a city that believed it was safe, someone did a thing that a whole country would spend years trying to forget.

It was planned for a long time. The people behind it crossed a border to be there. They lived under names that were not their own. And by the time anyone understood what had happened, they were already gone — into a crowd, then a harbour, then the hills.

Officer Sam is handed six of the best men in the service and a single order, with no limit set on how far he can go to carry it out: find them. Not only the hands that did it. Everyone who built it, paid for it, or stood aside and let it happen.

But the thread Sam pulls on runs further than a city, further than a border — all the way back to a boy who was shaped, patiently, over years, to strike this exact blow.

Who was killed, and why did it take a whole country down with them? Who could plan something like this — and who taught him how? Can Sam hold his team together through a hunt with no rules, no timeline, and no end in sight? And what will it cost each of them before it is finished?

Come find out what the officers who closed it saw. And why, once it was over, not one of them ever said its name out loud again.

Operation Pi.
