Outro: Next week, The Doctor and Leela will look into the mystery of the light that failed, the lighthouse at Fang Rock. It wasn't shot out by a kid with a BB gun. No, something more sophisticated than that: the minion of an alien battle fleet in deep space, intent on using the Earth as a battleground. Join us next Sunday night at 11 and witness "The Horror of Fang Rock." [source: ChicagoEpguides]
