Alec Mackenzie’s Art of Seduction by Jennifer Ashley

Alec Mackenzie knows that Lady Celia is key to finding his missing brother. The trouble is, Alec is supposed to be dead, and he needs the world to keep believing he is.
The artful ways of Alec Mackenzie.
Alec will do anything to find his brother, including pretend to be a penniless drawing master to London aristocrats. The one man who might know where his brother is being held is a powerful duke, and that duke has daughter who needs art lessons …
Lessons can lead to startling revelations …
Lady Celia is intrigued by the Scotsman, so obviously a warrior, who pretends he is not. She is also intrigued by his instruction on painting the human form, something no young lady should take an interest in. But Celia, ruined by The Disaster and already beyond hope, dares to let the Highlander teach her all he knows …

Note: Alec Mackenzie is the brother of Malcolm from The Stolen Mackenzie Bride. He is an ancestor of the Mackenzie family whose story begins with The Madness of Lord Ian Mackenzie.
