A regency romance and thriller combined: "The Marquess (Regency Nobles Book 2)" by Patricia Rice

The novel starts with a townhouse burning. The two cousins who live there manage to escape with their lives but the rich cousin is badly burned. The poor one wonders why people wanted something bad to happen with her nice cousin.

This romance novel is longer than the usual regency romance. This one does not stop after the hero and heroine slept with each other and fell in love (yes that seems the way to do it even in Regency romances nowadays). Only halfway down the book they then have to find out who is putting her life and that of her cousin in danger.

Although sometimes a bit slow the writer is good in world building and creating believable characters. I was sorry to see the book ending.
