Three Silver Birches — Ruth McCarthy Sears

Lovely young Christy Haven needed three years of medical treatment to recover from the shock of her father's mysterious death. Now, as she returned to her family home of Three Birches, it seemed as if her nightmare of fear was beginning again.

Christy's mother was now married to a man Christy despised. Even more horrible, her mother seemed completely under his spell and totally controlled by the servants he had hired to replace the old family retainers. When she realized that her father had died by a murderer's hand, Christy felt stripped of all defenses, and found she could rely one only the help of the handsome stranger she had met on the plan coming home. There was terrifyingly little time left to unmask the killer Christy knew, before she became the next victim!
