The Chalk Pit by Elly Griffiths - unbelievably, this is the 9th book in the Ruth Galloway series, and as usual it starts with the discovery of some bones in a "secret" tunnel under the city of Norwich, found when a local architect has a survey done with a plan to build an underground restaurant. His plans are seriously thrown out when Ruth reveals that the bones are probably only about 10 years old, therefore work has to stop as it could possibly be a murder victim. Then 2 homeless men are stabbed to death, one on the steps of the police station, and women start to go missing, including one who is the partner of one of the police team investigating the cases. This was another enjoyable read, with Ruth's daughter Kate now growing up, and more developments in Ruth's already complicated private life. 7.5/10
