The Arrangement

Widow Gail Saunders is struggling to support her eight-year-old son, Nicky, by running a small riding school when the Earl of Savile arrives to tell her that Nicky has unexpectedly inherited money from Savile's cousin. Gail and Nicky spend the summer at Savile Castle, where Gail falls in love with the charming Raoul, a man as far above her in social station as the sun is to the earth.

To add to her troubles, someone seems to be trying to kill Nicky. The threads of the story unwind to an unexpected yet satisfying conclusion (which I am not about to reveal here!).
