Kristal Cahll, a young clerk in the auction house, is killed in a suspicious hit and run accident.  This is the first of several suspicious fatalities befalling people connected to the auction.

In 1952, David was murdered while he was working on an expose of Nazi sympathizers.  The case was never solved.

James and Kincaid no longer work together. Superintendent Kincaid works in Scotland Yard, and Gemma is stationed at Notting Hill.  When Gemma’s investigations find links to the past and to David’s murder,  Kincaid is forced to pick up the "cold case." The two find  a web of treachery and deceit.

Kincaid and James have settled down with their sons from previous relationships (13-year-old Kit and 5-year-old Toby).  Gemma is trying to decide whether to accept Duncan’s proposal of marriage, while she has to come to terms with her mother’s cancer.

Where Memories Lie is well written with an interesting plot, smooth dialogue and a colorful cast.  It relates the progress of the love story between the two detectives, and their interaction with their families and friends.  It is like visiting old friends.

It shows the consequences of prejudice, greed, ambition and pride.  An appalling chapter of European history is exposed, showing how events dating even half a century ago can reach out to influence the present. As usual, Crombie has written a novel that keeps the reader’s attention continuously.  It doesn't seem possible, but she just gets better and better.

Highly recommended.
