‘A Dead Man’s Debt’ by Grace Elliot.
Celeste Armitage has a plan…and that plan doesn’t include marriage.
After deliberately humiliating a suitor, Celeste’s despairing parents exile her to the country. But once there she discovers a sketch book of daring nude studies and is shaken to find the artist is her hostess’s eldest son, Lord Ranulf Charing. This darkly cynical lord is exactly the sort of dissipated rogue she despises most…if only her blood didn’t heat at the thought of him…
Nothing is as it seems. Lord Ranulf’s life is a façade. Only he can save the Charing’s from disgrace as a blackmailer seeks to ruin his late brother’s reputation. But just as Ranulf dares to open his heart to Celeste, the fury of his nemesis is unleashed… facing him with the stark choice between true love and family duty. However when Celeste guesses the truth behind his rejection, Ranulf underestimates her resolve to clear his name and in so doing places the woman he loves in mortal danger….
