Collection of short ghost stories, one story about a sceptic ghost investigator [s]

[Gordon]

I remember reading this book in the 90's. It was a collection of short ghost stories, with a picture of a b/w castle on the cover. I don't remember a lot of the stories but there was one in particular about a sceptic ghost investigator who had a TV show. And on the show he was going to televise live him visiting the reportedly most haunted house in the country and staying overnight. So many people were watching it and hoping to see a ghost that it actually created a ghost in the house, I believe the book referred to that as a "spark" from all the people watching. I unfortunately can't remember anything else about it sorry...
I've tried Googling the cover but nothing turned up that was quite like it (some similar but not the same).
Any help appreciated!

Just checked and unfortunately that's not it, cheers though

An absolutely kick-ass collection of short stories. I had it out of the library a hundred times as a kid. In the story you are thinking of, the guy actually has a radio show. I have encountered the story in a collection for adults as well, under the title “The Believers”.

That'll be it! Really remember enjoying that one.
I must have gotten confused with the TV/Radio show as it's been a long time since I've read it!
Thanks very much for the help, I'll probably buy it now :)
