Mair Smyth came into the life of reality TV producer Johnathan Walton as an angel, promising salvation and friendship in a time of need. And not just an everyday angel, a glamorous one—with a storied family in Ireland who is fighting her over a whopping $25 million inheritance. But one day, after trying to help Mair out of a legal “snafu,” Johnathan accidentally learns the truth about the woman who has become his best friend: she’s actually an international con artist who has scammed him and a slew of other victims out of hundreds of thousands of dollars, from Los Angeles to Belfast. As Johnathan uncovers con after con—involving BDSM sex rings, witchcraft, a phony cancer diagnosis, and the scamming of a Los Angeles politician—he and other victims band together to bring Mair Smyth to justice. But can they stop her? Or will she go free in a world where her next mark is just a friendly smile away.
