Whiskey Beach by Nora Roberts

Eli Landen is suspected of murdering his adulterous wife, but there is no evidence to convict him.  Needing to escape, he returns to his family's ancestral home of Bluff House.  Eli finds himself caught off guard by his attraction to Abbra Walsh, the house's caretaker.  Then Abbra is attacked at the house by a mysterious intruder.  Eli knows that somehow this is connected with his wife's murder and other accidents that have been happening at Bluff House.  He realizes until he can solve the mystery he will never be at peace.  This was a very good romantic suspense novel with the mystery playing out to the very end.  I really liked it and would definitely suggest.
