Storyline The Truth:
The Truth (Discworld #25)
There's been a murder. Allegedly. William de Worde is the Discworld's first investigative journalist. He didn't mean to be - it was just an accident. But, as William fills his pages with reports of local club meetings and pictures of humorously shaped vegetables, dark forces high up in Ankh-Morpork's society are plotting to overthrow the city's ruler, Lord Vetinari.
