Once Upon a Time in Bath (The Brides of Bath #6)
Cheryl Bolen

When Miss Dorothea Pankhurst arrives in Bath with her ailing father—and the four cats she’s never without—she is ignorant of the ways of Society. Then the kindly Lord Appleton and his gracious sister take her under their wing. She’s immediately smitten with the handsome viscount and thrilled beyond measure when he asks for her hand in marriage.
After the murder of a young dealer at the gambling house where Appleton played, Dot and Appleton grow closer as they work together to find the killer. But they’re not fully aware of the sinister forces trying to pull them apart . . .
