Circles of Death by Marcia Talley is the twentieth book in her Hannah Ives series.

Noel, a young friend of Hannah’s, appeals to her for help. Noel and her sister both took a DNA test and discovered that, not only are they not sisters, but they are not related at all.

Hannah uses her genealogical skills to begin tracking down relatives of Noel’s. With those relatives, they can begin finding someone who might be able to shed some light on the mystery.

At the same time, Noel and Hannah look into the poisoning of several eagles nearby and discover a farm that is using a banned pesticide. The man Hannah suspects of using that pesticide is murdered, his body floating to her dock.

The twin investigations lead to a long ago murder. Although the identity of one of the murderers is not difficult to figure out, the identity of the other was a total surprise.

I’ve read that this might be the last of the Hannah Ives mysteries. I am sorry to hear it. I so enjoy spending time with her and her family and friends.
