"Thou shalt not steal is indeed the moral in this light-as-a-bubble comic caper" by the #1 New York Times-bestselling author (People). Appraising rare coins for Grandby & Sons, a venerable Madison Avenue auction house, is a dream come true for Mary Lou Bateson. She even gets a chance to inspect the Havistock Collection of priceless coins, which includes the Demaretion, a rare, ancient Greek silver piece. But when the Demaretion disappears just after her assessment, the young numismatist becomes the number-one suspect.   Placed on indefinite leave, Bateson enlists the help of a New York Police Department cop and an insurance detective to go behind the closed doors of one of New York's most powerful and untouchable families. The Havistocks are keeping some dangerous secrets, including a kleptomaniac daughter, a sex-addicted daughter-in-law, and a sleazy nest of adultery, pornography, and damning secrets someone is willing to kill to keep.
