'There's a kind of magic in masks. Masks conceal one face, but they reveal another. The one that only comes out in darkness . . .' The Opera House in Ankh-Morpork is home to music, theatrics and a harmless masked Ghost who lurks behind the scenes. But now a set of mysterious backstage murders may just stop the show. Agnes Nitt has left her rural home of Lancre in the hopes of launching a successful singing career in the big city. The only problem is, she doesn't quite look the part. And there are two witches who would much rather she return home to join their coven. Granny Weatherwax and Nanny Ogg have travelled to Ankh-Morpork to convince Agnes that life as a witch is much better than one on the stage. Only now they're caught up in a murder mystery featuring masks and maniacal laughter. And the show MUST go on . . .

Terry Pratchett
Engelsk forfatter som er kendt og elsket for sine "Discworld" bøger som der nu er kommet næsten 40 af. Det hele startede med bogen "The Colour of Magic" som udkom I 1983, om en klodset troldmand ved navn Rincewind. 3 år senere udkom fortsættelsen og siden har Pratchett ikke fået nogen nattesøvn fordi sultne fans sad og ventede på hans næste bog. Det stadigt voksende person galleri består blandt andet af heksen Granny Weatherwax, kufferten Luggage, døden DEATH, og vagten Vimes. Der er blevet lavet en del skuespil baseret på Pratchett's bøger og der er også blevet lavet tegnefilmsudgaver af to af dem.
