• Before Harry starts the conversation with her he thinks to himself "I decided to be careful. What were the odds she was really a little girl, as she appeared?" Hint hint.
  
• When Harry identifies her as the "Famous ghost of Graceland" she laughs and says "I have been called so" A pretty evasive answer, and more interestingly one that sound to me like something one of the Fae would say if avoiding the truth but speaking no lies.
  
• She seems to have a lot of knowledge about Dresden's current condition at the time, and knowledge of his new status as the Winter Knight, which I think is what she refers to when she calls him a "newborn". This is speculation on my part, since she then claims that Harry will be a "monster", but it is entirely possible to me as well that she could be referring to Harry's new status as a soul, or even something that has changed post-Changes in his mysterious-birth/starborn stuff. Regardless she knows way more than we'd expect a ghost to, even a really powerful one.
  
• Inez also seems to have some future knowledge of Harry's possible or even likely future, or at least knowledge of large events that are very much likely to happen in the future, which considering the enormity of the events that Harry is increasingly involved with is a scary amount of knowledge.
  
• She identifies monsters as "power and choice", which sounds like Dresden to me, who is usually reiterating that what you choose to do with your power is what defines you. Monsters also "provide a forge for the steeling of souls." Which seemed like an interesting bit of foreshadowing...
  
• Inez also says "This little world is so small. So dull. So dreary[...] You aren't shackled here, Mr. Dresden. Why remain?" You can take this to mean that she sees Harry' spirit could have/can move on to What-Comes-Next, but I dont't necessarily believe that that is what she is referring to if you assume that Inez is not merely a ghost. In either case, its a lot of insight for her to have.
  
• At the end of their conversation Harry says "You aren't the ghost of a little girl." To which she smiles and says "If I am no ghost than why do you look so haunted?", and then she abruptly vanishes without any fanfair, noise, visual, or any other indication that she was leaving somehow. You could take this to be an indication that she was a ghost, but I think that's a mistake. First off, this is after Harry notices that the statue is missing, i.e. Inez is the statue. If the ghost was controlling the statue, wouldnt the physical statue be there in place if the ghost teleported away in the same manner that Harry did in Ghost Story? If your next thought is that she is a ghost but she used magic to move the statue, that doesnt seem likely either as we later see that a ghost's magic doesn't work on the physical world. We also discover later that only absolutely insane ghosts can interact with the physical world. But Inez doesn't strike me as a pyscho-killer ghost; she's too polite, too talkative, too seemingly knowledgeable and too not-a-shade-at-Mortimers-house, like all the other insane killer ghosts.
  
• Harry then then remarks on her disappearance and refers to her as another "cryptic supernatural entity" like he so often has to deal with.
  
• Then Harry talks to the statue of Eternal Silence, who I and probably everyone else assumes is Demonreach. The very first thing Silence/Demonreach says is "An insufferable entity[...] Her soul is made of crooked lines." Her soul, he says, and as we know from Ghost Story someone's soul is very much not their ghost. As far as I can tell too, there is no reason why Demonreach would lie about this either. More importantly, or perhaps most importantly, is that shortly afterwards Harry is nearly blown apart by Demonreach's sheer force of will capital letters mind talk, part of in which Demonreach explains that "PRECONSIDERED VOCABULARY EXHAUSTED." It's a fairly short amount of dialogue leading up to that point too, meaning that 1) Demonreach knew in advance who Harry was going to be talking to, and 2) wanted Harry to know said hinty snippets of information about her/it.
