Greetings, Ghostwatchers! Well, who'd have thunk, Ghostwatch briefly returned once more to BBCTV last night, specifically BBC Two, during the most recent edition of Victoria Coren Mitchell-hosted, perpetual-brain-fazer, Only Connect. Yes, the game-show so intimidatingly tough, even I can't think of an adequately clever and pithy way to describe it. ... It's like, steak? A really well-done steak? Nah, forget it.
