There's an outbreak of petty pilfering from the inmates in Slade prison. Fletcher is disgusted - after all, stealing may be a job on the 'outside', but it's despicable when it happens 'inside'.

When Mr Mackay leaves Slade Prison, Fletcher thinks that "happy days are here again". Until, that is, he meets Mr Mackay's replacement.

It's Saturday afternoon and Fletcher looks forward to a quiet read. Everyone else seems to have other ideas about how Fletcher should be spending his time.

Fletcher is having a spell in the prison hospital with a broken ankle. He's sharing a ward with old Blanco, who tells him that another inmate has swindled him out of his belongings in a crooked card game. Fletcher hatches a plan to recover Blanco's belongings and to take revenge on the culprit.

Godber takes up boxing and wins a place in the prison championship, so Fletcher sees a chance for a bit of a flutter. Then Harry Grout takes an interest and insists that the fight is 'fixed'. When one of Grout's rivals takes a similar interest in Godber's opponent, it looks as if nobody can win. Fletcher, however, has other ideas.
