SOLVED. Anti hero, teacher/painter heroine, hit put on them both

[Rebecca]

The heroine painted a portrait of a man, who has a scar I think, and it's hanging in a gallery somewhere. The hero sees the painting, recognizes that it looks like him, even though they've never met. An attempt is made on the heroine's life and the hero saves her, taking her to his house with ultra high security. They end up falling for each other, but they're not safe there and they end up being attacked in his home, have to fake their death and live on some island somewhere. In the end I think she's also pregnant.
