Mr Murphy, 68, who lives in Huntingdon, spends his days passing judgement at Blackfriars Crown Court in London and his free time writing high-octane fiction. Following two political thrillers Removal and A Test of Resolve he has returned to the legal world of 1960s London, first explored in A Higher Duty, with his new book A Matter for the Jury. Scheduled for release in July, the book is the first in a series following the life and career of young barrister Ben Schroeder as he faces a capital murder case bound to test him to his limits. Mr Murphy, who formerly sat in courts at Huntingdon and Peterborough, said: Its something I have always enjoyed. I started trying to do it seriously in the 1980s but I didnt have very much time. Its only been in the last few years that I have taken it seriously and tried to get published. The trial in the story takes place in the old assize court in the Town Hall and the actual crime is committed on the river by St Ives it is very much a local book.INFORMATION: Visit www.petermurphyauthor.co.uk.
