Hi, this site isn't connected with any of the organisers whose events are listed here, but I'd try contacting some of the venues directly who've hosted murder mystery dinners and so on, like Hythe Imperial or Tim's Tapas or Bar Vasa and see who they used. Good luck and have a good birthday.
This is my site The Folkestone Gerald that I set up in a fury of excitement when we first came to Folkestone sometime in 2004. I'd been a frequent visitor for a while previous to that but I am technically one of those Down From Londons you get now. The site was updated more frequently with a calendar of events and voting for favourite venues and things, + I hear it was a useful resource for those who were moving to the area. Now I've moved out of Folkestone again (though just a couple of miles) it doesn't get as much love as it used to. Ironic really as Folkestone itself is now becoming the exciting place we always thought it was just about to. My name is not Gerald by the way, the name comes from a fake paper in an episode of Brasseye or something, the Portsmouth Gerald, and how there is a local newspaper here called the Folkestone Herald. Puns like this are great aren't they? Do contact me if you have anything to offer, email anythign @ this domain, or try @folkestone or @pauly on the twitter.
