The "Dear Boss" letter was signed 'Yours truly, Jack the Ripper' and a postcard referred to 'Saucy Jack' but this was just a nickname 'Jack' was a generic name for a man, like 'Spring-Heeled Jack' who terrorised the country at one time, or 'Jack-in-the-Green' who danced on May Day, dressed in green leaves. As the Ripper was never identified no one knows what his (or possibly her) real name was.
Well since they still aren't SURE who it was of course they don't know the actual name for sure. Yes there are some reasonable guesses based on the knowledge and such, but they really aren't sure.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
