Nightingale at Noon — Margaret Summerton

This is MELINDA VAUGHN -- young, beautiful, innocent of the world beyond her father's strange, shifting household, never asking why they were bound to the bleak house on the moor.

By the time she realized her father's life was in danger, she had fallen in love with his brooding, intense nemesis.

The two men--and the house--shared a secret almost too terrible to contemplate, with death as the denouement.

Melinda knew she could save only one of the two men she loved most in the world--but by saving one, she would have to destroy the other.
