The Booktalk agent listing is a textbook example of why researching agents through such online resources is not a great idea. It is incredibly out of date--along with currently active agents, it lists agents who have been out of business for ages or who have moved on to new agencies or simply have changed their addresses.
I can find some references to Caroline Carney and Book Deals Inc. dating back to before the turn of the century, but nothing recent. I suspect that this agent is not currently in business.
