Final Notice by Jo Dereske

So I'm a sucker for all things library - even airplane read mysteries. These have about the same literary weight as the Janet Evanovich or Diane Mott Davidson books but in this series the unlikely mystery solver is Helma Zukas, LIBRARIAN!!. And librarian in the Seattle area no less. There is even a love interest of sorts and a spicy friend. Not a meaningful, mystical read but a nice rest between the heavy hitters. And aren't all librarians mystery solvers of sorts? Of course they are!
