Colette Marceau has been stealing jewels for nearly as long as she can remember, following the centuries-old code of honor instilled in her by her mother, Annabel: take only from the cruel and unkind, and give to those in need. Never was their family tradition more important than seven decades earlier, during the Second World War, when Annabel and Colette worked side by side in Paris to fund the French Resistance.

But one night in 1942, it all went wrong. Annabel was arrested by the Germans, and Colette’s four-year-old sister, Liliane, disappeared in the chaos of the raid, along with an exquisite diamond bracelet sewn into the hem of her nightgown for safekeeping. Soon after, Annabel was executed, and Liliane’s body was found floating in the Seine—but the bracelet was nowhere to be found.

Seventy years later, Colette—who has “redistributed” $30 million in jewels over the decades to fund many worthy organizations—has done her best to put her tragic past behind her, but her life begins to unravel when the long-missing bracelet suddenly turns up in a museum exhibit in Boston. If Colette can discover where it has been all this time—and who owns it now—she may finally learn the truth about what happened to her sister. But she isn’t the only one for whom the bracelet holds answers, and when someone from her childhood lays claim to the diamonds, she’s forced to confront the ghosts of her past as never before. Against all odds, there may still be a chance to bring a murderer to justice—but first, Colette will have to summon the courage to open her own battered heart.
