Almost all of you know Cardinal Richelieu: he was the bad guy with a red cape in "The Man in the Iron Mask". Now, even though the book is fiction (and was written as such by Alexandre Dumas), the man in the iron mask really existed. I will tell you about him if we go to Vaux-le-Vicomte or to the French Riviera where we can visit one of his cells on a beautiful island.
