Dark Flame: Will political revenge destroy London?

Against the backdrop of a conflicted and disintegrating Middle East, and the threat of an emerging Islamic State, a British agent introduces a computer virus into the Iranian nuclear enrichment programme and the Supreme Leader want's revenge. A portable nuclear device is constructed inside a rucksack and an Iranian agent is landed on a remote Yorkshire beach. A detective is stabbed and lives are in danger as the agent and his British accomplice head for London. Detective Sergeant Rowdy Yates from Bradford Special Branch and James Turnbull from MI6 head up the chase to stop them, which culminates in a final dramatic encounter on the River Thames on Christmas Day.
