Stay of Execution (Bob Skinner series, Book 14)

Can you fight evil with evil...? DCC Bob Skinner faces his toughest investigation... Evil stalks the city of Edinburgh. This time the threat is bigger than the crooks, scam-artists or drug dealers who find their prey in the shadows of the streets. Some people are looking for a big-time hit. The body of a respectable businessman is found hanging from a tree; a veteran from a Belgian marching band is killed in a hit-and-run incident and another dies of an apparent heart attack. Excitement on the streets of Edinburgh is feverish as the city prepares for a huge rally to celebrate the return of Pope John the 25th to his hometown. The security has to be bulletproof. But there is a chink in the armour. Does Deputy Chief Constable Bob Skinner have the inner strength to find the answer to the biggest question of all?
