Sigma offers a collection of three literary works written by Oscar Wilde.

The collection includes a short story (The Canterville Ghost) and two comedy plays (The Importance of Being Earnest and An Ideal Husband).

Oscar Wilde used both satire and wit in his works as a didactic tool, using the comedy of it to mask his underlying social commentary and make it socially acceptable to criticize.

The book is a fascinating literature resource for both children and adults, who have a very good knowledge of English.
