Jack and Algernon are wealthy gentlemen. Jack (known to Algernon as Ernest) lives a respectable life in the country providing an example to his young ward Cecily. Algernon lives in luxury in London and has invented an imaginary invalid friend (Bunbury) whom he visits in the country whenever an unappealing social engagement presents itself. Jack has also invented a character - a wayward younger brother called Ernest whom he uses as pretext for going up to London and enjoying himself.
