Around one in the morning, the preliminary results came back.

Whatever had been in that mug was not an herbal supplement.

It was a prescription medication, present at a concentration far beyond any amount a doctor would ever administer — a dose the toxicologist described, plainly, as more than enough to kill an adult.

I did not need the clinical words.

I had trained as a physician.

I understood exactly what a lethal dose meant, and I understood that it had been waiting for me in a warm mug with my name on it.

I will not put the details here, and it is not only the law that keeps me from it.
