Written in 1920s, Stefan Zweig tells the story of a woman who is unrecognised and unrequited lover in Letter From Unknown Woman. This nameless young woman reached her unaware lover with this long letter by telling their memories from first day. As reader, while appreciating the patience of life long silence and hiding we don't know this woman as her lover who read the letter never recognised her too. With Zweig's literary talent this book has an unforgetable importance in our literature by emotion of being effaced that derived from never known; based on depth psychological side and human's love feeling we can find out darker sides and obsessions of people via this short but impressive book. Every reader who knows Zweig's success will admiringly read this book which is less known considering the other novels.
