>There's no forensics in Victorian England.

Doesn't Sherlock mention at some point in one of the books being able to teat a stain on a jacket and tell if it's blood or a fruit stain? Also people have used sorts of forensics for thousands of years. Granted it being used with crime solving seems to be more recently in the past couple hundred years.. but it was definitely around in Victorian England. Also thank you for saying this cause it made me go down a rabbit hole looking it all up lol. It's fascinating
