Captives of the Night by Loretta Chase

When the intriguing Comte d'Esmond enters a room, women swoon and men gnash their teeth. The count is fully accustomed to this reaction and brilliant at exploiting it. What he isn't prepared for is Leila Beaumont. One look from her tawny eyes is dangerously captivating. How ... troublesome. Esmond can't afford the distraction of an entanglement, however passionate it promises to be. He's supposed to be working --- for the government! --- and his employers want Leila's corrupt and treacherous husband brought to justice. When the spouse, unsurprisingly and conveniently, gets himself murdered, all Esmond has to do is clear Leila of suspicion and proceed to the next assignment.

But not being hanged for her husband's murder isn't enough for Leila. She wants to learn the truth --- all of it --- from Esmond, a man who's been lying all his life

Lord of Scoundrels by Loretta Chase

DETERMINED LADY

Tough-minded Jessica Trent's sole intention is to free her nitwit brother from the destructive influence of Sebastian Ballister, the notorious Marquess of Dain. She never expects to desire the arrogant, amoral cad. And when Dain's reciprocal passion places them in a scandalously compromising, and public, position, Jessica is left with no choice but to seek satisfaction...

LORD OF SCOUNDRELS

Damn the minx for tempting him, kissing him... and then forcing him to salvage her reputation! Lord Dain can't wait to put the infuriating bluestocking in her place—and in some amorous position. And if that means marriage, so be it!—though Sebastian is less than certain he can continue to remain aloof... and steel his heart to the sensuous, headstrong lady's considerable charms.

The Last Hellion by Loretta Chase

A ferocious conflict of wills...

Vere Mallory, the Duke of Ainswood, has everything--he's titled, he's rich, he's devastatingly good looking--and he seems determined to throw it all away. Disreputable, reckless, and wild, the last of the Mallory hellions is racing headlong to self-destruction...until a mind numbingly beautiful blonde Amazon knocks him off his feet--literally.

An incendiary passion...

Lydia Grenville is dedicated to protecting London's downtrodden. Dissolute noblemen like Ainswood are part of the problem, not the solution. She would like him to get his big, gorgeous carcass out of her way so that she can carry on with her work. The problem is, Ainswood can no more resist a challenge, especially in female form, than he can resist the trouble she seems to attract.

If they can only weather their personal firestorm...
they might survive the real danger that threatens all they hold dear.
