Rosalind Harker has given a lot of insight into RJ (His hands, his voice, his love for classical music (Bach) etc etc.)

The question is WHY is Jane not putting these to test? Why?

He is focused on his list of suspects, which is understandable, But what is stopping him from putting these men in front of Harker?

Don't you think that this list is made up? a diversion? Else, I think Jane would be the first person to use Harker for eliminating suspects from his list.

Also, he never made an attempt to get in touch with Rosalind......whats up with that? Some might argue that he may not want to risk rosalind's life by getting in tough with her.....but if RJ wants to kill her, he will anyways.....

I know heller mentioned that list is legit, but tell you what, he is a fictional writer, and like all fictional writers.....he may have lied to the press (with good intentions of providing us with a surprise ending)
