Historical fiction. Good concept. Dual timelines. But not a great novel.

London, 1953.  Louise is still adjusting to her postwar role as a housewife when she discovers a necklace in a box at a secondhand shop. The box is marked with the name of a department store in Paris, and she is certain she has seen the necklace before, when she worked with the Red Cross in Nazi-occupied Europe —and that it holds the key to the mysterious death of her friend Franny during the war.

Flashback to NAZI occupied Paris. Lévitan—a once-glamorous furniture store converted by the Nazis into a forced labor camp, and Helaine, a woman who was imprisoned there, torn apart from her husband when the Germans invaded France.

The two stories are intertwined, but how?

That’s the mystery.
