It's not often a Nobel Prize winner gets murdered... on your patch... very likely by a member of your own family.
DCI Phil Benholme has the reputation for being a little soft because he tries to see both sides of every story. And if he hadn't on this occasion, the murder of Professor Unwala - Nobel Prize winner of 1945 - would have been recorded as a tragic accident.
Was the elderly man a victim of a violent burglary? Or of a racist assault by Britforce troopers? Or did he know something about the collection of Celtic coins thought to be buried nearby?
Clearly Inspector Benholme has a number of leads to follow up. Unfortunately they all point to one person - Conor Benholme. What does a 'soft cop' do when his teenage son is also his prime suspect?
