Martha Kirkland: The Secret Nabob

The Secret Nabob by Martha Kirkland was published by Signet in January 1996 and is the story of Madeline Wycliff who has two sisters causing her stress on top of their financial losses which is heading towards disaster when the new mysterious neighbor moves into Balenger Hall and becomes intimate with their family.

I think that this is a pretty cover by Allan Kass. Our hero seems to have been out riding and stops to greet the heroine. The different colors are vibrant and springlike.  The heroine seems to like his attention and we predict a summer wedding!
