An evenings entertainment- with murders you can really hum
The Opera House, Ankh-Morpork a huge, rambling building, where innocent young sopranos are lured to their destiny by a strangely-familiar evil mastermind in a hideously deformed evening dress. At least, he hopes so. But Granny Weatherwax, Discworlds most famous witch, is in the audience. And she doesnt hold with that sort of thing.
