Michael Murray is beginning to realise that his new-found political "friends" are not being entirely above-board with him. Jim Nelson, meanwhile, gains some respite from Murray's persecution when he becomes a local hero in a tragic accident. Though his attempt to save his pupil, Robbie Burns, is not successful, his efforts earn him the undying loyalty of Robbie's father, Norman, and his formidable brothers. After a time, however, Murray resumes the pressure and Jim begins to come unravelled, manifesting as a new phobia for bridges. His doctor refers him to a psychiatrist, Dr. Goldup. At the hotel where Murray is carrying out most of his plotting, his eye is caught by a new arrival, a beautiful and poised woman called Barbara Douglas.
