Summerton: Lady Eleanor Mysteries, Volume 1 (Unabridged‪)‬

He married for money, she wed by force. On the brink of losing everything, the Duke of Summerton marries heiress Caroline Howlett, but at what cost? She wants neither his crumbling estate nor his title, and what is he, as a man, without them? Before he can resolve this dilemma, something more dangerous than doubt threatens their marriage. When Caroline said she'd rather be dead than married to the duke, she hadn't meant it literally. Forced into marriage by her guardian, Caroline doesn't give a fig for the idle life of the aristocracy. She wants to run her father's enterprises, and she will, once dead bodies stop getting in the way. Aided by Summerton's widowed aunt, amateur sleuth Lady Eleanor, the duke and his reluctant bride scramble to discover just who is trying to kill them. Neither considered love part of the bargain.
