“Book Descriptions: Rosamund and Geoffrey have a happy, companionable marriage, with only the adolescent eccentricities of their son Peter to disturb the even tenor of their life. Then Lindy--clever, attractive, unmarried, and very, very friendly--moves into the house next door. There's little to indicate that she is after anything more than friendship, but she changes Rosamund's life in too many ways for Rosamund to bear--and she takes over Geoffrey.
Which might have explained why Rosamund, running a high fever during an attack of flu, dreamed she had killed Lindy--except that after the flu and fever pass, there is, to Rosamund's mounting terror, evidence that the dream had not been a dream after all. Lindy has inexplicably disappeared. ” DRIVE
