Di Cesare's Pregnant Mistress (Harlequin comics)

Interior designer Tamsin, by the bane of her own beauty, is mistaken to be aiming for a seat as the wife of the Earl of Grainger. While there is nothing but amity between the two, the earl's dear friend Bruno plots to tear the two apart. Bruno approaches Tamsin with his debonair charm and quickly leads her, naked, into his bed. Little does she know that it's merely a trap to show the earl how loose of a woman Tamsin really is!
