A shriek rings out over the tents and boardwalks of Carnival l'Morai, followed by a plea for help from Marie, the blind juggler. Other performers arrive at the young woman's wagon to find her covered in blood. On the bed beside her lies the sword-swallower, impaled upon his own blade.

Marie and her friends have few clues to track down the murderer - until they find the next body and the next... Their quest to capture the killer reveals horrors undreamed of, even for a troop of freakish performers trapped in the heart of the Dark Domains.
