The 1980s. The Falklands War. The IRA. The Miners' Strike. Cruise Missiles. Anti-Nuclear Protests. And in the thick of it all, beautiful Claire Oldham, the revolution's poster girl - until the day she turns up brutally murdered. A young, troubled drifter, Martin Grove, is swiftly prosecuted and jailed for the crime. Fast forward twenty years: Martin Grove walks free, cleared by advances in forensic science, seemingly the victim of a miscarriage of justice. Fast forward a few more years, come right up to date: Martin Grove is shot dead in his reclusive home, 'executed' at close range. DCI Jacobson and his team are on the case. But which case? And do the answers lie in the dangerous past or in the even more terrifying present?
