Scary, and bloody funny (literally), BBC Two introduces a new comedy-thriller from Reece Shearsmith and Steve Pemberton (two of the acclaimed creators of The League Of Gentlemen), which focuses on the lives of five apparently unconnected characters. Episode One begins with a mystery. Mr Lomax, a blind recluse with an unusual hobby; Robert, a telekinetic dwarf; Mr Jelly, an embittered, hook-handed clown; David, a serial-killer obsessed man-child; and Joy, a deranged but caring midwife, each receive black-edged cards bearing the anonymous message: "I know what you did." As the past catches up with these five apparently unconnected characters, their lives begin to unravel. Pemberton and Shearsmith are joined by a rich mix of talent, including Dawn French, Dame Eileen Atkins, Nicholas Le Prevost, David Bamber, Janet McTeer, Christopher Biggins, Daisy Haggard, Debbie Chazen, Daniel Kaluuya and Adrian Scarborough. If you thought The League of Gentlemen was warped, you haven't seen anything yet.
