Liza Colton has a career as a singer. Her mother is her manager and is overbearing.
Liza goes to a local doctor in Saratoga Springs because her voice is going. He prescribes food and rest. Lots of rest. Nick becomes involved in Liza's life and helps her out by hiding her at his house after a man came into the hospital and threatened her. Slowly, she trusts Nick with the secret that she has been in contact with her cousin, Emily, who was the initial target of the murder and is believed to have been kidnapped but is hiding out from the family as Emily (and Liza) believe Meredith is behind the attempted murder.
Patsy as Meredith has no plans of being left as a pauper and wants her husband dead so as to inherit. She also plans on killing Emily, and Liza if need be. She wants to find her identical twin - so that she can get rid of her as a threat.
There was not much about Louise Meredith in this book (that I remember). But the police were filled in on Liza's suspicions, especially as the man kept hounding her - until he was killed when being chased by police.
Nick and Liza develop feelings towards each other, but Liza believes she is incapable of having children and Nick has dreams of a large family. Liza is found by reporters, and leaves for her apartment, then stays in hotels under assumed names.
Nick's ex-wife, Daphne, tells him that he has a child - but Nick is highly suspicious. His suspicions are confirmed - he is not the child's father. But it is too late to inform Liza of this fact, as she has read the papers and believes it...... so their reunion when Nick starts his vacation to look for her and she is in Saratoga Springs is not the stereotypical reunion. Instead, they profess their love for each other later, and THEN Liza tells him that she is pregnant and the complications her body has.
They plan to elope and inform people of their marriage afterwards.
