As previously revealed, Lynsey (Karen Hassan) will soon be left horrified when Silas issues her with a sinister challenge. The evil villain promises that if she correctly guesses who he's lining up as his next victim, he'll hand himself in - but if she fails, another girl will die.
Silas (Jeff Rawle) already has heavily-pregnant Mercedes McQueen held captive in a vault, while Theresa, Amy, Texas and Lynsey herself are also possible targets.
Lynsey has until midnight on Halloween to solve Silas's mystery - but does she have any chance of playing him at his own game?
Hollyoaks airs weeknights at 6.30pm on Channel 4 and 7pm on E4.
