Who's murdering harmless old men? Who's poisoning the Patrician? As autumn fogs hold Ankh-Morpork in their grip, the City Watch has to track down a murderer who can't be seen.Maybe the golems know something - but the solemn men of clay, who work all day and night and are never any trouble to anyone, have started to commit suicide...
It's not as if the Watch hasn't got problems of its own. There's a werewolf suffering from Pre-Lunar Tension, Corporal Nobbs is hob-nobbing with the nobs, and there's something really strange about the new dwarf recruit, especially his earrings and eyeshadow.
Who can you trust when there are mobs on the street and plotters in the night and all the clues point the wrong way? In the gloom of the night, Watch Commander Sir Samuel Vimes finds that the truth may not be out there after all...
