MI6 plan to assassinate the leading maker of IEDs - roadside bombs- as he leaves his house in Iran. But first, they need to know when he is leaving. So it is that Danny 'Badger' Baxter finds himself in Iran, lumbered with a partner he loathes, lying next to a mosquito-infested marsh, observing the house. And knowing that if they are caught, Her Majesty's Government will deny all knowledge of them.

He had been to the limit. Then they sent him further. Gary - 'Gaz' - Baldwin is a watcher, not a killer. Operating with a special forces unit deep in Syria, he is to sit in a hide, observe a village, report back and leave. But the appalling atrocity he witnesses will change his life forever. Before long, he is living as a handyman on the Orkney islands, far from Syria, far from the army, not far enough from the memories that have all but destroyed him.

For the Borelli clan are major players in the Camorra, a crime network more close-knit and ruthless than the Sicilian Mafia.

Officially, the Cold War is over, and the hand of friendship has been exchanged in public. In private, though, the intelligence war continues. A British trawler strays into Russian waters. On its return, the captain has a package for British Intelligence. For the next four years, a high-ranking Russian naval officer provides MI6 with priceless information. But suddenly he goes quiet.

Now, Liz Carlyle and her Counter Terrorism unit in MI5 have been charged with the task of watching the international under-the-counter arms trade and British Intelligence forces have become increasingly concerned that extremist Al-Qaeda jihadis are building their power base ready to launch another attack.
