Episode 3

Claudia sees George turn up for his class as usual and is horrified that he hasn't been arrested. Ejected from the Winter house for giving them false hope, she refuses to believe that George could be innocent and desperately starts digging into his past, choosing to ignore her increasing unease about her son's strange behaviour. Claudia learns from Joanne's wheelchair-bound son Simon that Joanne may have been the last to see Emily alive. At the same time, she discovers that George was involved in another death, and is convinced that he really is the culprit. A confrontation uncovers the truth and Claudia realises the damage she has done — but not before the media announce a suspect has been arrested for the murder of Emily.
