A routine morning train journey through rural countryside becomes a nightmare when gunfire tears through the carriage windows. Panic erupts. Lives are lost. And in the chaos, something far more deliberate goes unnoticed. Poppy survives by instinct, escaping into the fields with her dog, Rex. But what she saw will place her at the centre of a rapidly unfolding investigation. Detective Mark Taylor and his team are called in to help multiple agencies make sense of the impossible. A rural shooting. A clean escape. And inside the same train, a second, targeted killing hidden in plain sight. As evidence begins to surface, a quiet actuary named Oliver Bailey emerges as the shooter. But nothing about him fits. No history. No motive. No explanation. Behind the scenes, a different story is taking shape. One of organised crime, control, and calculated violence. A man who keeps his hands clean. A system designed to remain invisible. Because this was never just a shooting. It was a message. And someone made sure it was delivered.
