Who is Fernanda in count of Monte cristo?

first of all its Fernand not Fernanda! first and foremost this is Mercedes' cousin. he is obsessively in love with her and this leads him to commit his crime against Edmond Dantes (the count of Monte cristo later in the book). when fernand, danglars and caderouse are discussing their despise of edmond and danglars writes the dooming letter it is fernand who sends it. once edmond becomes the count of Monte cristo and resolves to take revenge Fernand suffers the fate of commiting suicide after being mentally tortured by the various characters that the count becomes it is when Edmond reveals himself to Fernand that he flees the counts mansion to discover his daughter and mother leaving and it is then that he commits suicide. this is of course to go along with everything that the count had done to him in the build up! this book was recommended to me by my grandmother and i must tell you that no other books come close to this book. it is the best book i have ever or will ever read in my entire life and if you have not read this book i plead with you to read it. it will be lifechanging...
