Steve Pemberton has warned this series of Whitechapel is set to scare viewers.
The actor, who plays the show's Ed Buchan, explained to TV Times that there would be a lot of spooky scenes coming up.
He said: "Spooky things start to happen at the station, unexplained occurrences that are really scary and creepy. It feels like something is coming alive and a presence is lurking there.
"It gets progressively worse each week and every character is affected in a different way. You sense there is a manifestation of evil which is stalking them and it gets really dark. That's the big thing this series - it's going to be very frightening for people - hopefully."
Steve admitted he would be following a few superstitions in the hope that the series goes down well.
He said: "There are always things that are unexplained and we all do things like touch wood or make a cross or say a silent prayer. I don't believe in anything like that, but I always touch wood. I am touching it now and hoping that this series goes down well."
Whitechapel continues on ITV on Wednesdays.
