Talking to the Dead by Harry Bingham. "This suspenseful novel is the first in a series by Bingham featuring Welsh detective Fiona Griffiths, Cambridge-educated and idiosyncratic (to say the least). Fiona frequently obliges the reader (if not her bosses) by going rogue. The whole series is good, but start with the first."  Editor's note: As of this writing, the kindle version of this book is FREE.  if, like me, you are perversely put off by free books (or by the cheesy cover) don't be.  It's an excellent series.
