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, Annabel was arrested by the Germans, and Colette’s four-year-old sister, Liliane, disappeared, 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’s life begins to unravel when the long-missing bracelet suddenly turns up in a museum exhibit in Boston.
