Detective Inspector Hunter Wilson is a loyal friend and a fair leader.
He is called to the scene of a murder in Edinburgh where the corpse has been fatally shot. He is dismayed to find the victim is his friend and colleague, George Reinbold. Hunter must investigate Reinbold’s murky past in Germany to identify George’s killer.
At the same time, Hunter is tasked with looking into a previously undetected criminal gang supplying drugs from Peru. There seems to be no connection between the murder and the drug supply until Hunter unexpectedly secures help from inmates of the local jail.
Hunter’s investigations are hampered by distracted members of his team and unobservant witnesses.
Reinbold was not the quiet, old man Hunter believed him to be and his killer bore their grudge for a lifetime.
