A Wicked Business by Emma V Leech

Fate or fortune…
In Felix Knight’s opinion, his father is the greatest industrialist that ever lived. Born in the workhouse and now one of the wealthiest men in the land, Gabriel Knight is impossible to ignore, and he has enemies who despise him for his rise to power.
Living in the shadow of such a towering figure isn’t easy, however, and Felix is working all hours to emulate his charismatic and successful sire. The last thing he needs right now is a distraction.

Which is a pity…
A woman of spirit and determination…
Lady Belinda Madox-Brown is tired of men believing she exists only to look pretty and laugh at their jokes. Her father has little interest in her beyond her value on the marriage mart and Belinda has had enough. She wants to do something, and a close friendship with her rather unconventional lady’s maid has provided the perfect outlet. But women cannot just go around spending money and creating business opportunities without a man – drat it.
