Amid Zydeco rhythms and popping champagne corks, bead-draped revelers are moving into the streets, and Jekyl Hardy is playing host to a party in his elegant French Quarter apartment. On a wild night like this, anything can happen. The guests - including scrapbook-store owner Carmela Bertrand - never imagine it will be murder. But as the evening progresses, Jekyl's neighbor, float designer Archie Baudier, is found on the balcony choked to death with a barbed wire garrote.

The only things wilder than the crime are the far-flung theories about who did it - from a ritualistic slaying to a mob hit to the outlandish work of a rival Mardi Gras float builder. Handsome detective Edgar Babcock isn't buying any of it. Neither is Carmela, and the odd clues are bringing out the sleuth in her: gold paint on the victim's shoes, a strange coin found next to his body, his ransacked apartment, and the peculiar fact that no one at the party really knew him. Only one thing is clear: Whoever killed Archie is following Carmela - straight into the chaos of Mardi Gras.
