The Four Temperaments — Yona Zeldis McDonough

Oscar Kornblatt has been a first violinist with the New York City Ballet for so many years that he scarcely notices the throngs of eager young dancers who fill the ranks of the corps de ballet. But Ginny Valentine catches his eye, and when he comes to know her he becomes utterly enchanted by her. One night when Ruth, his quietly independent wife, is away, he brings Ginny back to his Upper West Side apartment and the two become lovers.

While the affair doesn't last, Oscar's attachment to Ginny continues to flourish. He invites her to join his family for Thanksgiving dinner, where she meets and falls in love with Oscar's eldest son, Gabriel, home from San Francisco for the holiday. Gabriel, married to a beautiful, highly unstable woman, finds himself falling under Ginny's spell. As the bonds of the family begin to erode, Ruth takes drastic and shocking measures to salvage what is most precious to her: her baby granddaughter, Isobel.
