You Have Been Warned - A Spoiler Free look at Ghost Stories

Not to be confused with Ghost Stories (when will they do that on Tabletop?), Ghost Stories is a play that's just started a new three month West End run.  I first saw it three years ago when it was on at the Duke of York theatre, and last weekend I caught the start of the new run at the Arts Theatre.  Now the show relies a lot on some pretty big secrets; in fact, as you leave, you walk past a sign saying how many people now know the secrets (which when I was there stood at just over 310,000).  As such, I am going to work very hard to make sure I don't give anything away, while still giving a full and fair review.  Challenge Accepted.
