Sweet, so just hang around pubs in Cheltenham till you find the spook pub, then pal up with them, find out who would most likely take a bribe (I don't know, maybe one who plays the puggies[0] a lot would be a good place to start) offer a big wad of cash and boom! you can find out about anything or anyone... Shit, that's probably how the tabloids know who to send PI's after, there must be stuff leaking out of that place :-(
