Pbs show was about two kids a boy and a girl and they were going through this dimension with a headless dude. First they were in this library and saw help backwards on the window. Please anybody help me with this show?

Are you looking for Ghost Writer?

No it wasn't ghostwriter. I know that show. One of guy in this dimension his head was floating around and telling these two kids what they have to do. Hope you can figure it out.

I remember that show too!! I have no idea what the name of it was but I remember that the bad guy rode a motercycle and wore black... I'm looking for a answer too- I posted what I could remember about it just recently hoping for an answer. And your right- it's not ghostwriter. I watched that show religiously, it wasn't that one. But the girl was his younger sister-not older.

Putnme1 - I think I found what you're looking for -try this address to a show called Storylords...
