The Stone Circle - Elly Griffiths

nIn a chilling entry to the award-winning Ruth Galloway series, Ruth and DCI Nelson are haunted by a ghost from their past, just as their future lands on shaky ground. n DCI Nelson has been receiving threatening letters. They are anonymous, yet reminiscent of ones he has received in the past, from the person who drew him into a case that's haunted him for years. At the same time, Ruth receives a letter purporting to be from that very same person--her former mentor, and the reason she first started working with Nelson. But the author of those letters is dead. Or is he? n n The past is reaching out for Ruth and Nelson, and its grip is deadly. nn
