Patrick Sanderson, a member of a prominent Glasgow family and a City Councillor is found dead in Glasgow’s Botanic Gardens. There are very few clues, just an old, World War 2 pistol and a sighting of a street dweller who may have witnessed the murder.

Carillion struggles to find a motive for the killing and digging through the Sanderson family history he finds more than he bargained for. As the Sanderson family’s skeletons are uncovered and the only possible witness is found dead things get more complicated.

Politics, money and murder come together with Carillion and SCRU caught in the middle. Time is short and his team under pressure to solve the mystery and break the cycle of revenge.
