Do you think this is a waste of time?

I have a posting on craigslist for a HUGE lot of vintage books. The books are from 1932, and it's a collectors edition. It's 82 books. It's a collection of "the Works of" and has many of the authors from back in the day, like Shakespeare, Hawthorne and so on.
Anyway, a lady responded to my ad yesterday asking if I was "Still in possession of the books?".

I wrote her back, and said that I was.

This morning, I get this response from her. I'm copying the email that I received here.

Hi Craig,

I am interested, but how would I know you aren't scamming me? Your advisory is somewhat of a put off. Tell me more about the books. Their history up to your possession of them, and more about your self. You don't give prospective buyers much to work with.

Do you want to sell the books, or scare people away?

What in the world? Why is this how she responded? I've never dealt with someone like this on Craigslist before. Is this a waste of time? Is this person probably not even interested in the books at all and is just trying to get on my nerves? My listing is PERFECTLY clear, I stated info in the ad, and this email from this person is making me feel a little creepy. Should I respond to it? Should I just ignore? I feel like telling this person NEVERMIND I do have the books but I don't want to sell them to you. LOL

And part of me thinks they are scamming me, because they are calling me "craig".
What do you think?
