Carrigstown is all go these days. If it's not affairs, it's kidnappings. Well okay, there's only been the one kidnapping recently, but it's been going on for an AGE. Six months to be exact, which is the equivalent of at least two years in soapland.

Young Katy went missing on the show back in May, and while initially there was no sign whatsoever of her, Fair City marked their 4000th episode in September with viewers getting a look at Katy alive and well but trapped in some kind of bunker.

Since then, we've been speculating on who exactly could be behind Katy's disappearance, with RTE releasing a list of five possible suspects last week which included, Oisin, Tommy, Ciaran, Cathal and Stella, with 45% voting Ciaran as the kidnapper in our poll. Tonight, however, you are finally going to find out who is behind it.

There are also going to be some violent scenes between Emmet and Tommy but we cannot tell you if they're related to the big reveal or not.

However, we do have some sneak-peak images of Emmet going all Bryan Mills on Tommy Dillon. And sure poor Debbie is distraught.

Catch it all unfold tonight on Fair City at 8pm on RTE1.
