Cruel Zinc Melodies — Glen Cook

Glen Cook's popular P.I., Garrett, uncovers the dark side of the fantasy city of TunFaire, where no one is to be trusted -- especially not beautiful women.

Garrett's P.I. instincts warn him that the knock on his door one winter morning means trouble. He's not wrong. His visitors are a pack of young lovelies led by his main squeeze, Tinnie Tate, and her friend Alyx Weider, the spoiled, sassy daughter of the largest brewer in town.

Alyx's father needs Garrett's help. He's building TunFaire's biggest theater, but the workers are being attacked by all manner of creepy things -- from giant insects to shadowy ghosts. Garrett takes the case because, after all, working for the Weiders means free beer. But as Garrett will soon learn, taking a job at this theater also means serious drama.
