The Woman in Blue by Elly Griffiths

I've been missing Elly Griffith's heroine, archeologist Ruth Galloway, for a while, so was thrilled to have the opportunity to read this new tale in the series.  Time surely flies, as her little Kate is now old enough to go to school and they are blessed with a very flexible childminder so that Ruth can pursue her academic career as well as getting involved in helping to solve murder cases in close co-operation with Kate's father, Harry Nelson and their druid pal, Cathbad,  There is more suspense than archeology in this adventure, except that Ruth comes up with a pivotal piece of evidence in the course of her investigations.  The book is atmospheric and well written, and the developing background story of the character's relationships develops in counterpoint to a threatening series of crimes that kept me guessing.
