Penny Dreadful

Hi!

In a Downton Abbey episode of season 6 someone says "It's not a Penny Dreadful with confessions from the box." They were discussing a police investigation or trial or something.

What does it mean in this context? When I try to google it, all I get is results for the TV series of this name, which I never watched, so I have no idea what it is about.

Many thanks!
