Edinburgh’s annual GhostFest is now firmly established in the calendar of “things to do in Edinburgh”. The most recent happening, from 9 to 18 May, featured a whole range of events not included in any of the previous GhostFests – some pure entertainment and some of a slightly more serious nature. The festival is now four years old, and still delivers fun to a wide audience, from the open minded through to the true believer with a scattering of skeptics for good measure. One complaint is simply that there are now so many things happening that it is physically impossible to attend everything.
