At my sister’s wedding, my champagne tasted strange and my vision went blurry. Her mother-in-law grabbed me. “You are making a scene,” she hissed, covering my mouth during the vows. She had me locked in a storage room to silence me. She didn’t realize a server had seen what happened—and had already taken action.

How did my sister’s wedding turn into a crime scene in under twenty minutes?

My sister Felicity was halfway down the aisle when I realized the champagne I’d just sipped tasted wrong. It was bitter and chalky, with a weird metallic aftertaste that made my tongue feel thick. I set the glass down and tried to focus, but my vision started getting blurry. The string quartet playing Canon in D sounded like it was underwater. My hands started tingling first, then my feet. I stared at the champagne flute, realizing something was seriously wrong.
