For Melissa May, happily married to Gavin for the best part of thirty years, life couldn't get much better. Then Melissa's world is ripped apart when she discovers Gavin is HIV positive. The shock of his duplicity and irresponsible behaviour re-awakens a psychiatric condition Melissa has battled since childhood. Fuelled by rage and a heightened sense of right and wrong, Melissa takes matters into her own hands. Homicide detective Adam Stanley is investigating what appear to be several random murders. When evidence comes to light, linking the victims, the case seems cut and dried and an arrest is made. However, despite all the damning evidence, including a detailed confession, Adam is certain the killer is still out there. Now all he has to do is prove it.
