The Night Hawks by Elly Griffiths (Ruth Galloway series No. 13)

Ruth Galloway a forensic archaelogist of repute does not like amateur detectives. Very little patience with them. She is however good at not showing exactly how she feels and when a body is discovered in a nearby trench, it is a Bronze Age one and right up her street. She did not think that it will lead to a murder and another body to be discovered and dealt with. She did not think very much of the Metal Detectorists who also haunted the sites hoping to discover buried treasure in large measure. She had her reservations about all of them. When the body count starts piling up, and when there are too many coincidences the mystery deepens. Added to the tension is the fact that DI Nelson is also the father of Ruth's daughter and there is so much unwritten past and present and future in their dealings. The fact that he is now married to someone else, with a very young baby son does not detract from the chemistry that exists between the two. Story No. 13 in the series, this is not getting stale or boring. Sent by Houghton Mifflin Harcourt for an unbiased review, courtesy of Netgalley.
