A new matron arrives, the terrifying and puritanical Miss Fox. Even Loftus, who knew her when he was a young doctor, is scared of her. Duncan and Paul attempt to get rid of her by sending love letters supposedly by Bingham but all in vain. Duncan and Bingham fall out over the same girl, Sandra, and Duncan decides to get at Bingham by putting a bucket of whitewash on top of the door so that it will fall him. It claims another victim instead - but it gets rid of the Fox!
