Stranded between the year's two spookiest holidays is The Secret Of Crickley Hall, (Sunday, 9pm). It may sound like a mysterious Noel Edmonds vehicle, but it is in fact a major three-part spine-tingler based on a James Herbert novel.
You can tell it's 'major' and 'three-part' because it's in absolutely no hurry to get anywhere. Like Don't Look Now it starts with every parent's worst nightmare. But for the rest of the hour it doesn't do a whole lot, just busies itself with setting things up for the next two weeks.
