A murder in a public place, a victim who hides his killer’s intent…

A German citizen is murdered in Belfast Botanic Gardens. Investigating, DCI Gawn Girvin concludes it is a revenge killing. But she draws a blank from CCTV and forensics.

The only clue is the top of a perfume bottle found at the scene. As frustration sets in, Girvin develops a hunch that by tracing the victim’s criminal connections, they’ve followed the wrong scent.

A young female university student seen nearby may hold the only key to unlocking the case. And like a bloodhound, Girvin follows the new leads.

But being ex-army, her cold demeanour is a magnet for risk takers. It means she gets results, but also puts herself in danger. And she could be charging into her biggest challenge yet.
