going straight S1 E2 going to be alright

Fletch goes to see his probation officer, who is disappointed that he has not got a job. Fletch explains that he was going to work in a cardboard box factory but his wife Isobel ran off with the owner. Fletch plans to dig up some loot he buried in a turnip field in Esssex before his imprisonment but when he gets to the field he finds that a housing estate has been built over it. At least the probation officer has got him a job - digging.
