Even deadlier than terrorists … are the men trying to stop them. People-smuggling, counterfeit currency and attempted murder. It’s all in a day’s work for undercover cop Dan ‘Spider’ Shepherd. But what starts as a run-of-the mill investigation quickly turns into a matter of life and death when he uncovers a terrorist cell on a mission of death and destruction. The target: hundreds of passengers on a cross-channel train deep below the English Channel.

  The SAS are used to deaths during combat - it goes with the turf. But when one of their own is said to have committed suicide in Thailand, red flags are raised. Pete Green wasn't the sort of soldier who would ever take his own life - and no one is more sure of that than his twin brother, Davie. Davie is determined to fly to the Land Of Smiles to find out what really happened to his twin brother. But if he is going to find out the truth he'll need help - the sort of help only SAS Sergeant Matt Standing can provide. But soon after they arrive they come under attack, leaving Standing to investigate on his own. There are clearly people who want to shut down all enquiries and Standing knows he will have to use all his SAS jungle skills to survive. This will be the toughest of assignments but nothing will come between him and the truth.

Former SAS trooper turned undercover cop Dan ‘Spider’ Shepherd knows there are no easy solutions in the war against terrorism. But when a killer starts to target pardoned IRA terrorists, Shepherd has to put his life on the line to protect his former enemies.
