Neil's handler sends him on an undercover mission to Belfast posing as an expat Irishman. His job is to get close to a local IRA godfather and find out when and how he plans to bring in a new shipment of arms and ammunition. Neil succeeds in winning the man's confidence--and the romantic attentions of his daughter. But suspicions about his true identity begin to mount, and Neil must complete his mission before his cover is blown.

Ex-SAS soldier John Neil is brought out of retirement by a secretive government controller, and is asked to investigate an old SAS colleague who's taken to a life of crime. An MP is exposed to blackmail, and the conspiracy uncovered leads all the way back to Nazi Germany.

Investigating the murder of a Major in military intelligence, ex-solider Jon Neil follows two lines of enquiry. One is the beautiful girlfriend of the murdered man, the other takes him undercover at a merchant bank. He unearths an international drugs deal, and the Controller insists he remains in place, even when a murderous Columbian appears on the scene.

Final part in a trilogy about John Neil, an ex-SAS soldier who is persuaded to end his semi-retirement by a powerful and secretive government department. He is sent to Paris to do a deal with a former KGB agent who has the names of two people he recruited as potential saboteurs in the 1970s. The agent is killed, and Neil becomes the target of a hit man.
