Pushed to breaking point, Cara Burrows abandons her family and escapes to a five-star spa resort she can't afford. Late at night, exhausted and desperate, she lets herself into her hotel room and is shocked to find it already occupied by a man and a teenage girl. A simple mistake on the part of the hotel receptionist but Cara's fear intensifies when she works out that the girl she saw in the hotel room is someone she can't possibly have seen: Melody Chapa, whose parents are serving life sentences for her murder. Cara doesn't know what to trust: everything she's read and heard about the case, or the evidence of her own eyes. Did she really see Melody?
