The show must go on as murder music & mayhem run riot in the night... 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. & she doesnt hold with that sort of thing. So theres going to be trouble (but nevertheless a good evenins entertainment with murders you can really hum...)
