I tagged the book to explain my name, but I can't leave it in the shadow!
It's a play by Pierre Corneille, and to describe it in his own words, it is 《Un étrange monstre》( a strange monster). If you like theater and want to read a french classic, go for it. It's really funny and the plot is amazing.
P.S. The title in english is " The Illusion"... It miss the comical part and the pun!
