THE DETECTVE - DS George Cross loves puzzles - he's good at them - and he immediately spots one when he begins investigating the death of former mayor Peggy Frampton. It looks like a burglary that went horribly wrong to most but George can see what others can't - that this was murder. THE PUZZLE - After her political career ended, Peggy became a controversial blogger whose forthright opinions attracted a battalion of online trolls. And then there's her family- an unfaithful husband and a gambling-addicted son. With yet more enemies in her past, the potential suspects are unending. THE SUSPECTS - Cross must unpick the never-ending list of seedy connections to find her killer - but the sheer number of suspects is clouding his usually impeccable logic. He's a relentlessly methodical detective, but no case can last forever. And politics can be a dangerous game - especially for people who don't know the rules . . .
