Genuine Letter

[Tani]

One of the things that bothers me a little is when some letters are considered hoaxes and for a lot of people it's 'case closed' after that. This has made me wonder - to what are we mentally comparing these 'hoaxes' and what would a genuine Ripper letter look like? How would we recognise it if it were sent?

Genuine - something containing information that only the killer could have know when it was written, some specific details etc.
