Delusion in Death (In Death Novel)

It was just another after-work happy-hour bar downtown. The noise intensified. The crowd seemed oppressive. Some sharp words were exchanged, some pushing and shoving. Then the madness descended. And after twelve minutes of chaos and violence, eighty people lay dead. Eve Dallas is trying to sort out the inexplicable events. It appears the bar patrons were exposed to a cocktail of chemicals and illegal drugs that could drive people into temporary insanity - if not kill them outright. But that doesn't explain who would unleash such horror - or why. Eve's husband, Roarke, happens to own the bar, yet he's convinced the attack wasn't directed at him. It's bigger than that. And if Eve can't figure it out fast, it could happen again, anytime, anywhere. Because it's airborne.
