My daughter suddenly became unwell at her birthday celebration. I thought it was just a frightening accident. Then security footage revealed my sister’s secret.

Nobody answered.

Allison looked directly at Vanessa.

“She made the lemonade. She brought Lucy that cup herself.”

Vanessa answered quickly.

“Because she is my niece and the birthday girl.”

Michael moved the cup away from everyone else.

“Nobody touches this until the paramedics arrive.”

That was when another detail returned to Allison.

Vanessa had not poured Lucy’s drink from the large dispenser in front of the guests.

She had come from the kitchen carrying the unicorn cup already filled.

At the time, it had seemed like a small thing.

Now it was part of a sequence.

The drink had tasted strange to Lucy. She had described it as tasting “like medicine.”
