Bernard has an annoying habit of being honourable - even when playing golf. But what of his pupils? When Duffy invites Sharon to a half-term Majorcan holiday, will the habit be catching?

When "Hank" Abbott, private detective, goes into action, he opens the cupboards that let out the skeletons. One produces a rash of honesty from Potter. The other makes Cromwell feel that Miss Ewell might yet be won back from Mr Sibley.

Bernard and 5C drop in at the Conservative Club and make new friends. Maureen also makes a new friend, but he is more interested in dropping out.

It takes a face in a thousand to star in an advertising campaign, but Bernard and Potter make it a two-horse race.

When Cromwell succumbs to an attack of administrative megalomania, the Charge of the Light Brigade is cancelled, a class is lost at the cinema and Mr Price is driven to drink.

It looks as though Fenn Street will lose yet another teacher when Price applies for a job in industry. But can he really make the break?

Potter's repeated demands for an assistant are finally heeded, and Sidney Noakes arrives at Fenn Street.

The amalgamation with neighbouring Weaver Street and the possibility of Fenn Street going comprehensive is more than the Fenn Street staff can cope with. Potter has to decide where his loyalties lie.

Headmaster Cromwell has a new toy to help him communicate with the whole school, but Price does not want to keep in touch, for an old enemy is out to get him.
