Lonesome Road

There were times when Rachel Treherne fervently wished that her beloved father had left his fortune to somebody else, so overburdened did she feel with the administration of her estate. And never more so than now for, although she was surrounded by relatives who depended on her, whom she loved and who must surely love her, there was no doubt in her mind that somebody was trying to kill her. Threatening letters could be ignored, odd tasting chocolates can be rejected, but when snakes are left in her bed, Rachel is convinced that someone means her terrible harm.
Her only chance of a future life lay with Miss Silver, and Miss Silver was well on the way to unmasking the murderer when they struck again.
