Murder to a Jazz Beat

Jessica arrives early in New Orleans on a book tour and spends some time as a tourist in the French Corner. On the night her host takes her out to a night club for the final performance of a popular Jazz band before relocating out of state, the leader drops dead, apparently from a heart attack. However, at Jessica's prodding, the police discover he was actually poisoned and there were several people, including several bandmates, who wanted the man dead.
