The Mad Hatters Tea Party

Alice spawned multiple personality threads to analyse the results. There was a chemical. Inert, and not lethal. But it was unusual. It looked like one of the medications that Dr Travis took for his heart. The human analysis showed that this was the case, but to Alice it looked... Unusual.

Gathering up the threads, like a spider gathering up her silk, Alice came across a conclusion that seemed as strange as the compound itself.

The molecule in question became lethal when it was inverted. Maybe it had been inverted while inside Travis's system, and then changed back?

Curiouser and curiouser!
