You find a box in the attic.
Ready-for-retail-sale bottles are stacked in this box. They are labeled “Purity Pills”. A stack of papers lies atop the bottles. The papers give the chemical formula for the pills, directions for synthesis, and explain that any man who swallows a pill will have perfect rational control over his libido.
A note on top of the stack reads: “If this gets out, we’re ruined. — H. H.”
