At Last the Rogue Returns by Adele Clee

A lady discovers that the monster of her nightmares just might be the hero of her dreams.

The lady labels him a devil.
Miss Lydia Lovell is on a quest for justice. For years, Lord Greystone’s tenants have suffered at his hands. While he abandoned his estate to rusticate abroad, poverty and illness crippled those who depend upon him. Now Greystone has come home, and Lydia is determined to make him pay.

Greystone returns for revenge.
Having spent five years abroad making his fortune, Miles Oakley, Viscount Greystone, returns to England with one goal in mind – to ruin those responsible for his mother’s humiliation. The plan is in place. But when a spirited lady accosts him at the manor’s gates, hurling her ridiculous accusations, he discovers another shocking betrayal.

The course of true love never runs smoothly.
But Lydia has more to worry about than Greystone’s tenants. Her brother’s cunning wife wants control over Lydia’s inheritance and is plotting ways to accomplish her goal. And damn Greystone. Lydia cannot fight her attraction to the man she’s spent years despising.
When threats of murder and blackmail throw them together, and passion burns with ferocious intensity, Miles and Lydia must overthrow their enemies if they have any hope of surrendering to love.
