Sex and Salmonella than any of the other Tory Bauer mysteries because it was the first one to come out nationally (though it's the 2nd mystery in the series- long story). It only had one printing, and it's the rarest of the titles. For awhile, back in the 90's, used paperback copies of the book were selling for over $100. Don't worry, the ebook price will be $2.99, just like Funeral Food. I think there are a lot of people who never got to read this book, and soon (like, within a couple of weeks), it'll be available again!
And yes, there is a carnival in the story.
Many thousands of thanks to my son Curtis, who is doing the covers for me, even though he has plenty of his own work to do.
