Random London Ghost Of The Day
Some say that the modern buses have no soul. Perhaps that's no bad thing, if the legend of the Notting Hill ghostbus has any merit. Legend has it that a spectral bus — much like the Knight Bus from Harry Potter — haunts the streets around Ladbroke Grove station. The first recorded incident was in 1934, when a man driving along Cambridge Gardens suddenly swerved, crashed and died. Some witnesses swore that the driver had taken action to avoid an approaching bus, which had then vanished; others only saw the sudden swerve. More reports appeared. Witnesses would often see the diabolical omnibus around 1.15am, usually in May. It is described as a driverless Number 7, and always with its lights switched off. The last serious report came in 1990, so the next one's long overdue. It's all obviously poppycock, of course, but keep the story in mind if you find yourself in Ladbroke Grove after the Tube has gone. (Originally published by the same author in Curiocity.)
Weather
What's that coming over the hill is it some sunshine? Is it some sunshine? Why, yes it is some sunshine. The BBC predicts several hours of unsullied brightness until the clouds remuster in the late afternoon. It'll remain fairly chilly, though.
