In Nursery Rhymes, D.C.I. Keir Dickson put two young brothers behind bars for eight years. In They Never Saw It Coming, the government devised a two-year plan to reduce the congested English prisons. A priest by the name of Fr. Sean O'Brien takes on the task of rehabilitating the two brothers, or so it appeared. The real purpose of taking on these two brothers was to wreak vengeance on the police and British army. D.C.I. Keir Dickson foils the priest plan, who is injured, and loses his right hand when he is finally captured.
The story now continues with Sean O'Brien escaping from the hospital bed, and is still intent on seeking revenge: revenge for the death of his two twin brothers that were shot trying to run a roadblock in Ireland by British soldiers, and for the torture he was submitted to.
D.C.I. Keir Dickson and his team now have the task of finding O'Brien, and finally bringing him to justice for good.
