Adina knows more about Baroque art than anyone else in the United States. Ester knows more about forging Baroque art than anyone else in the United States. Their every encounter simmers with flirtation and frustration. But as long as they stand on opposite sides of the law, their relationship remains firmly in "dalliance" mode.Then the Chicago Museum calls Adina to authenticate a long-lost painting by underappreciated Baroque master Artemisia Gentileschi. Though the painting is obviously one of Ester's forgeries, Adina is tempted to authenticate it anyway, to both bring attention to an underappreciated artist and perhaps have a chance at more than angry words and stolen moments with Ester.
