As a side benefit of pet-sitting for porcinea, I found and read two Amanda Cross books I hadn't realized existed. (The other is a short story collection.) Honest Doubt is her first novel with a detective other than Kate Fansler (though Kate is a character in this one), and her first novel told in first-person rather than tight third.

It also has footnotes. Not weird or silly footnotes a la Nabokov (I'm told) or Pratchett: actual academic-style footnotes, to books and stories the characters refer to. I had a lot of fun reading it: it flows well, and the viewpoint character is good company. Then I got to the end, wandered off, and started scribbling notes.
