The Black Diamond

Sylvia Thompson, using the name Jane Bingham, became nursemaid to Bobby Palin in order to find out what had really happened to her sister, Bobby's former helper. In no time she found herself in love with her employer, suspicious of his second wife, and horrified by her sister's fate--which might have been sealed by the infamous black diamond mourning ring. Victorian Gothic by Joan Smith, writing as Jennie Gallant; originally published by Fawcett Crest
