Impossible, because Sherlock Holmes wasn't a real person.
The Holmes in the new movie is not at all like the real Sherlock Holmes! To quote a critic (that I happen to agree with) he is like Rambo quoting poetry.
No, he was a work of complete fiction with no real historical basis.
The book you are asking about might be called 'Castle Rouge: A Novel of Suspense featuring Sherlock Holmes, Irene Adler, and Jack the Ripper' by Carole Nelson Douglas, which is a parody or pastiche of the Sherlock Holmes character. It is not a true Sherlock Holmes story. There have been many stories and books written by fans of Conan Doyle who have created alternative Sherlock Holmes stories, attempting to be as true to the original story as possible.

There were no connections between the two. Remember that Jack the Ripper was real and Sherlock Holmes was a fictitious character. There have been a couple of attempts to merge the two and there is at least one movie that connects the two.
