Thread of Suspicion — Jane Peart

When Nell Winston is offered a position as a companion to Allegra Selkirk, a young woman who has been paralyzed in a carriage accident, she considers this unexpected opportunity a welcome change from her job as dining room hostess at a seaside resort. But upon her arrival at the Selkirk's isolated country estate, she discovers a situation far different from what she imagined. From the moment Nell steps through the magnificent front door at Hope's End, she fells uneasy. Her reception is unwelcoming, if not hostile, and every method she uses to encourage Allegra is met with resistance. As their friendship develops and Nell's affection for the young woman deepens, she determines to discover the secrets that keep Allegra a helpless invalid. When Nell follows the thread of suspicion that leads to unexpected sources, she finds not only Allegra but also herself in deadly danger.
