Shirley and Andrew vow to unmask the killer

The Mitchells are panicking over DS Crisp's latest arrest. At the same time, Shirley visits Andrew and Dot to apologise for her recent behaviour. She admits that she wanted Andrew to be guilty as she was jealous over his closeness to Heather.

Keen to make amends, Shirley visits the police station with Andrew and verifies his story by presenting the train tickets to DS Crisp. Later, things look worse for the Mitchell schemers as Shirley - with Andrew's help - vows to find the identity of Heather's killer.

Meanwhile, Jean and Michael discuss the murder case during a chat at The Vic. As the person arrested by the police had lots of money on them, Michael teases Jean that she could be the murderer's next victim due to her scratch card win. He then plants the seed that Jean should invest the cash…

Elsewhere, a guilt-ridden Mandy knows that she has to do the right thing, although she isn't the only one with a secret in the Beale household - Ian is still planning to buy back the café.
