Blaketon was the police sergeant in Ashfordly before retiring to run first the post office and then the Aidensfield Arms.
He is a disciplinarian, a sceptic and part-time private investigator. He is also Rob Walker's mentor and grandfather figure.
Oscar is fearlessly direct, and will rarely admit that he is wrong. He has no truck with the radical social developments of the 60s, and believes that the country has been going downhill at a rate of knots since the end of the war.
Blaketon has found it hard to give up his career and often gives the other policemen advice, whether solicited or not.
Occasionally he forgets that he is no longer a police officer and tries to take charge.
