Clive Formby's combine harvester has been torched and he is convinced Ken Dixon in Ashfordly is behind it. A witness saw a shady character staying at her empty neighbouring house overnight and wandering about with a fuel can. The "shady" character turns out to be the new police constable in Aidensfield after PC Crane's death. His name is Rob Walker and Oscar is not too happy about him. His father Jake was a well-known criminal and Blaketon is convinced that nothing good will ever come out of that family. Dr. Merrick is concerned about one of her patients, Gilbert Percy, and persuades Vernon Scripps to clean the old man's cottage. Percy is very fond of Shakespeare and makes Vernon read the old master's plays to him instead.
