Acting DI Samantha Nixon is on a single-minded mission to find the Sun Hill serial killer when a young woman called Vicki Casson goes missing. The latest clue is a website found by Simon Kitson which shows photographs of the body of one of the previous victims, posted by an anonymous user calling himself ""The Baptist"". When Nixon's teenage daughter Abigail is brought into the station drunk, will Nixon recognise this cry for help from her desperately lonely daughter? When a newborn baby is abducted from St Hugh's hospital, DS Debbie McAllister takes on the case, despite being on maternity leave. PC Kerry Young demands an answer from her fiance, PC Luke Ashton, about his true feelings.
