When Jim hears the boys’ detested new Eton suits have been stolen in a burglary, he smells a rat. Then the masters’ clothes are also pilfered, with the village ladies arriving any minute to hear a recital by the musical Moussaka Ensemble.

An old boy now in commercial TV offers the Headmaster an appearance on the Break The Bank quiz show, with questions supplied beforehand. Jim chooses maths as his subject, relying on his top pupil to come up with the answers.

A photo of a naked lady is found in the school magazine under the heading ‘Proposed new addition to hobbies room’, and Edwards is sacked! Mr. Foster takes over as Head, but, determined to clear his name, Jim stays on — as a schoolboy!

Lady Westbury offers to halve Prof. Edward’s rent if he helps her humanitarian cause by accepting an ex-Pentonville inmate on the staff. Mr. Tozer gains the respect of the boys, but Jim is adamant that he must go.

The Headmaster decides to accompany the boys on their form outing to the Tate Gallery. All his trepidations prove well founded when one pupil and a piece of sculpture disappear.

As chief of entertainments, Jim books Max Bygraves to perform at the Chiselbury village hall Grand Variety Concert.
