The Stone Circle: Ruth Galloway #11    by Elly Griffiths Order:  USA  Can Houghton Mifflin, 2019 (2019) Hardcover, e-Book      Reviewed by Lyn Seippel The newest Ruth Galloway mystery harks back to the first installment of the series with an anonymous letter sent to DCI Nelson. It refers to a missing child and looks very much like letters he received on a case from years past. That case that was solved with the help of forensic archeologist Ruth Galloway. The present case is also about a missing child. It's a cold case from 1981. The disappearance of a young girl during a street party celebrating the wedding of Prince Charles and Lady Diana Spencer was never solved. The letters Nelson received then and now are anonymous, but although intended to mimic the original letters, the new ones can't be from the same writer. The originals were later traced to Ruth Galloway's mentor, Norwegian professor Erik Anderssen. Anderssen has been dead for years, but someone knows enough about the first case to use the information to have the body turn up at a current archeological dig run by Erik's son Leif Anderssen. Meanwhile Nelson's wife is about to give birth to a baby boy and Ruth is thinking of moving to Cambridge. She's in a relationship that could make her happy, and with Nelson about to become a father again, she must think of her own future and that of her young daughter. It would be hard to imagine Ruth living somewhere other than the saltmarsh. The story's surprising ending is another salute to the first book in the series. I always enjoy the Ruth Galloway series. The characters draw me in even more than the mystery that holds the story together. Even the smallest role may be a continuing one with tendrils that might help solve a future mystery.
