Jack has two identities because his best friend Algernon Moncrieff knows him as Ernest. In addition, Jack has a girlfriend named Gwendolen Fairfax who is the cousin of his friend. The play opens as Algernon is suspecting something fishy with Jack after he finds a writing addressed to Uncle Jack which claims to come from little Cecily. The fact that Jack lives a double life does not surprise Algernon because the latter believes that this is common in modern life.
