Where Memories Lie by Deborah Crombie

Police detectives Gemma James and Duncan Kincaid are having a dinner party for their colleagues when Gemmaʼs friend, Dr. Erika Rosenthal, calls and asks for her help. Erika has seen a picture in an auction catalog of a brooch her father made over fifty years ago. Erika lost the brooch in Germany during World War II and sheʼs wondering how it came to be in the brochure. Gemmaʼs inquiries about the piece of jewelry cause the auction house employees to become very uneasy. Then someone is killed and Duncan and his team head up the investigation. Gemma unofficially helps out while simultaneously dealing with the sudden illness of her mother and lingering thoughts that she and Duncan should marry. The mystery goes back and forth between the past (where the reader learns that Erikaʼs husband was murdered in the 1950ʼs) and the present in order to uncover the culprit. Another enjoyable police procedural from Crombie.
