The arrival of the new bishop at Mitrebury and his orders for all clergy to take up jogging and a diet of boiled rice sends the men of the cloth scurrying to the Old Chapterhouse Surgery for their dose of sick notes. This added burden seems rather too much for the vastly overworked doctors to bear; they might even have to cancel their afternoon golf to meet the demand. This is simply not on and each doctor silently vows that he would retire instantly if only there were someone reliable to take over. So when they learn that two of their oldest and dearest friends now have qualified doctors as children, they seize their opportunity to escape. After all, these are genes they can depend upon - of course it never occurred to any of them that these valiant new doctors might be women!
