In 1974 a budding writer, 3 musicians, & a hanger-on spend the summer at an Italian villa. The summer ends in murder but the 2 women in the party go on to achieve enormous artistic & commercial success. In the present day, frenemies Emily & Chess stay in the villa to reconnect & jumpstart their flagging writing careers & end up uncovering new information about the murder.
I preferred the historical story but both were interesting till the end.
