EastEnders' Shirley Carter will begin to grow suspicious of Phil Mitchell next week amid his ongoing problems with DCI Keeble.
Things will get worse for Phil in the upcoming episodes when Keeble threatens to go after the rest of his family unless Jimmie is dropped from defending Billie in court.
The DCI gets her way as Ritchie goes on to tell a distraught Billy that Jimmie can no longer represent him and, as Phil is speaking with Shirley at The Vic, he's clearly filled with guilt as he watches their interaction.

Shirley quickly becomes suspicious when she notices Phil and Ritchie's subtle exchange, and when Phil receives a text from Keeble to meet, Shirley secretly follows him and gets some incriminating evidence on Phil which she can use to her advantage.
As Rocky attempts to make a speech for Jay, Shirley comes up with a devious idea...
Phil isn't the only Mitchell Shirley will use to her advantage, though. Next week, she'll blackmail Sam for more money and threaten to tell Phil she's been scamming him for months if she fails to comply.

Jonah, who's been looking for Sam, grabs her arm, but Phil intervenes and punches him, though Jonah makes a chilling threat to the family in return.
