The So Blue Marble

THE SO BLUE MARBLE. IT PROMISED TREASURE AND DELIVERED MURDER.
Once the dashing, top-hatted twins had the marble, they would do to Griselda what they had done to others.
Her estranged husband, Con, a thousand miles away, could no longer save her. A bloody trail wound about the so blue marble, years of theft, torture, violence; whispers of secret riches, gold, diamonds, rubies as big as the moon. Soon it would be Griselda's chance to lie motionless.
An exquisite beauty with lemon-ice hair, a Princeton-educated inspector and identical laughing twins with lethal-tipped, gold-knobbed canes inhabit this startling mystery.
