I fail to understand what is to be gained by writing a book about a murderous, criminal loser - who no-one, not even his family, appear to want to remember.
I would consider it an unworthy project, and I couldn't really imagine where you'd even cover the cost of producing the book. Surely there must be other little-known, good people, who are worth writing a book about?
I have read all I need to know about Forman from the couple of newspaper pages reporting on his short, murderously evil, criminal career.
The only thing that Forman ever distinguished himself at, was stooping as low as any other bitter, twisted, and truly evil, suicide bomber.
