In the third and final programme in this series, Harold Williamson looks at two men who enjoy the work they are doing. Not highly qualified and not generously paid - they have jobs that give them fulfilment: variety, purpose and freedom to work on their own initiative. Both are detectives: one, an older self-styled 'thief-catcher' in Pudsey, Yorkshire; the other younger, concerned with reforming as well as catching offenders, in Doncaster. Real detectives with opinions about the law, the human race - and even Softly, Softly.
