You saw something terrible? now you?ll never be safe again. Ellie can?t stop having nightmares. It?s been the same ever since she saw the car accident where a man lost his life. Awaiting the trial of the dangerous driver where she?s the primary witness she finds herself befriending Samantha the widow of the man who died. And - as their children also become friends - their lives become intrinsically entangled. But then Ellie starts thinking she?s being followed. She wants to believe it?s paranoia. But then she receives a note - written in red ink like blood - it says just one word: ?LIAR??
