Next week EastEnders fans will see Ian Beale (Adam Woodyatt) become increasingly desperate to keep his whereabouts on the night of daughter Lucy's murder a secret.
Warning: spoiler alert!
Having paid Rainie Cross (Tanya Franks) for sex on the night in question, Ian decides to confront Rainie and convince her that it is in her best interests to stay quiet.
A show source told Daily Star Sunday: "Ian's had a lot of sympathy and everyone has rallied round him since Lucy's death. If they should find out what he was doing on the night she was murdered it would cause quite a scandal."
The source continued: "The police would want to know why he lied about his whereabouts and his life would once again be in ruins.
"How far Ian is prepared to go to keep Rainie quiet remains to be seen."
The scenes will air on BBC One and RTÉ One on Monday July 21.
