I have far too many things I'd like to talk about, so I'd like to ask your opinion.  Out of all the stuff you've seen on this blog, what do you think might make the most interesting talk for a library audience?  Keep in mind that some of the audience, but not all, will be mystery fans.  Some, but not all, will be historical fans, and of course everyone is a reader.  What do you think for a subject?

If you happen to be within reach of Merrylands, I'd love to see you there.
