In the closed community of the Tower of London, an identity swap and an arranged marriage are put into play to save the head of a condemned man. A lovesick court jester and his maid stumble into the plot with heartbreaking results. Cat-Like Tread return with their ninth original production, and punch to the heart of the matter in an abridged version of Gilbert and Sullivan's operatic masterpiece. 'For careful execution and straightforward fun, it is difficult to imagine many recent productions of Gilbert and Sullivan have beaten Cat-Like Tread' **** (AllEdinburghTheatre.com).
