The Devil's Book
Isabella Thorne

Everyone knows Mr. Hobson is an evil man who killed his brother for the inheritance, and perhaps killed his earlier wives.
But Ruby will not gossip. She needs this job.
She has a fancy for a footman, Mr. Putnam, but it will be a long while before they are able to marry.
One day while dusting the library, a strange thing happens and she is convicted to act.
Ruby learns that God can always intervene in evil, and turn a man's heart, no matter how bleak the present may look.
A short, gothic tale with a HEA.
