The Broken Teaglass, by Emily Arsenault

Wonderful, literate and intricate mystery. Lexicographers Mona and Billy discover a long ago murder mystery buried in the citation files where they work for America's oldest dictionary company. Aside from the unique nature of their jobs, the way the story came together in so many little pieces was great- this was very different, and very good. There was a kind of bildungsroman feel to it as well, which is so rare in a mystery.
