Death in Glasgow

When the body of Holly Campbell is found on the train tracks to Glasgow Central, the police decide it's a clear suicide. She was a troubled young woman. She'd tried before. But Sergeant May Mackay can't let one detail go. The ticket found in Holly's pocket. If Holly never wanted to come home, why did she buy a return ticket? As Sergeant Mackay looks into this question, she realises that one ticket can lead to dangerous alleyways, forgotten paths and a terrifying network of secrets.
