Mystery shadows the canals of Doskvol, a murky port city besieged by ghosts. The Silkworms are a criminal crew torn by internal conflict as an apocalyptic prophecy unfolds in the background of the colorful Festival. Inspector Cellars pursues justice, and uncovers a threat that could destroy the world. This is the third book in a series inspired by "Blades in the Dark," a role playing game by John Harper.
