Aldeburgh is, as any fan of the traditional ghost story knows, the place where M.R. James set 'A Warning to the Curious'. Well, you'll be pleased to hear that a genuinely eerie phenomenon has occurred there - a public pool has turned blood red. Not, though, because of some ancient curse - it seems they used a cleaning product that goes red in sunlight before dispersing. Well, that's the official story. But it still looks pretty weird.
