A woman rising out of grief, and a man baffled by familial and marital treachery, intersect via a stoically terrified child. They independently and together try to thread their ways though the baffling outcomes and actions that the motives of others have subjected them to. Such a good book. I have read this quite a few times since I first came across it and it never ceases to make my spine tingle and raise the odd goosebump with the ratcheting tension. Such a good romantic thriller. Mary Stewart is the master of this style of story.
