The Alibi Man by Tami Hoag

This is another crime thriller by Tami Hoag and again she keeps the romance fairly low key. She does have one of those damaged heroines though (I think this is the second in a series featuring Elena Estes). This can sometimes seem like a plot device rather than a an essential part of the character. Good plot though and interesting developments (although a depressing view of the moneyed horsey set in Florida).
