Mrs. Theresa Marshall has it all at 44. A 5th Avenue residence and a showplace in Southhampton, along with being rich and well pedigreed in New York 20th Century WASP society. She stands by her philandering husband, Sylvo, who she knows has had a mistress since they married. Enter, war hero, ace pilot who lives to tell his story. Young, handsome Captain Octavian Rofrano quickly becomes her twice-a-week lover. She calls him Boy. Did I mention he was young? He is 22 and their sexual attraction sizzles! Octavian, though inexperienced but proper, wants her to obtain a divorce and marry him.

However, a woman with her social standing and fabulous wealth does not need to divorce as she and Sylvo have an understanding. You can cheat but be discreet. This is the first part of the love triangle...Older woman with a young man, Mrs. Marshall and the Boy.

Her brother, Jay, or Ox, as she calls him is a bachelor, man about town who is almost past his bloom. He is pedigreed, drinks too much and has no money. He meets 19 year old Sophie Fortescue, heiress to her inventor father's' fortune. She is lovely, innocent, and unsophisticated. Her inheritance adds a lot to his attraction and Ox needs to share his intentions with Theresa, his beloved sister.

When he tells Theresa that he has fallen in love and wishes to marry Sophie, she is pleased and wants to help. She coaxes Ox to be romantic and urges him to send a Cavalier with an engagement ring to propose to Sophie on his behalf. She sends Octavian as the Cavalier and when he presents Sophie with a gorgeous engagement ring and a formal request for marriage to Ox, the sparks fly! The second part of the love triangle....young woman with an older man. Sophie and Octavian.

The roaring 1920's era in Manhattan is filled with booze, adultery, glitz and glamour set in an unforgettable time. Jazz is the music of the day and speakeasies with gin is where the action is. Scandals, a long ago unsolved murder, dubbed as "The Trial of the Century" is solved. Filled with lies, secrets and betrayals, the plot weaves through twists and turns with an ending filled with surprises. I loved this book, as I have all of Beatriz William's offerings. A special talent who takes me on delightful journeys, meeting characters I sometimes love, sometimes hate.

A CERTAIN AGE is based on Richard Strauss's Opera DER ROSENKAVALIER which enacts a struggle between the old and the new, both with money, youth and maturity. Along with a rivalry between a beautiful young virgin and a woman of "a certain age." It was pure magic. I am still thinking about it long after I turned the last page, completely captivated.
