A fugitive bomb maker dies in a police ambush in Marseille... A global terrorist collective meets in Paris to plan an attack on a European target... The terror cells have been activated and elite bombers from ETA and the Real IRA are already making their move, intent on using a device that will cause carnage on an unimaginable scale. Their motivation has its origins in a purpose shared decades earlier, leaving them with a legacy of grief and greed. In London, only two things matter to Detective Chief Inspector Emma Rydan – her daughter and her job. After a joint counter-terrorism arrest with the Guardia Civil ends in chaos, Rydan and her seconded junior officer Detective Sergeant Kent find themselves faced with a rising body count, few clues and a race against the clock. On the other side of the Irish Sea, tension escalates in a high security wing of Her Majesty’s Prison Maghaberry as one of the political prisoners attempts to derail the plot. In desperation he is left with one final, frantic option, and everything to lose. The net tightens, taking the police enquiry to Cambridge, where lethal menace brings violent confrontation to the colleges and departments of the historic university. Whilst the terrorists make their final preparations, Kent is working the electronic surveillance systems at New Scotland Yard. He has the streets of the capital at his fingertips, but where is the target and when will they strike? And is he even looking in the right country? As the manhunt hurtles towards its terrifying conclusion, Rydan realises her daughter is closest to the greatest threat. And they’re both out of time.
