On the Glasgow night shift, paramedic Alex knows how to keep people alive. Then a callout with a bitter, citrus sting ends in a boy’s death—and a pattern he can’t ignore. A courier collapses. An addict goes rigid with impossible symptoms. Somewhere in the city, a patient zero is being made on purpose.

As Glasgow tilts toward cup-final day and a packed Hampden Park, Alex’s instincts put him on the radar of a shadow unit—Division Nine—who believe an elusive chemist, codename “Vale,” is testing a weapon in plain sight. They want Alex close. Closer than is safe.

To stop a mass-casualty nightmare, Alex will have to break rules he’s lived by, run toward the danger, and decide how much of himself he’s willing to spend to keep strangers breathing.

Gritty, grounded, and propulsive, Division Nine is Glasgow noir with a paramedic’s eye—an unflinching thriller about duty, complicity, and the split-second ethics of saving a life when the city becomes the patient.
