A detailed examination of the contents has proved them to be the original case files that detail the complete police investigation into - the Matter of the Hound of the Baskervilles.

For the very first time the public are able to read the witness statements, medical files and original police reports that chronicle the case from the death of Sir Charles Baskerville and the death of the hound at the hand of Mr Sherlock Holmes.
