Proof of Heaven

Dr. Potter bent over and focused on the manometer, the transparent
vertical tube into which the cerebrospinal fluid would emerge. Laura’s
first surprise was that the fluid didn’t drip but gushed out—due to

Her second surprise was the fluid’s appearance. The slightest opacity
would tell her I was in deep trouble. What shot out into the manometer
was viscous and white, with a subtle tinge of green.
My spinal fluid was full of pus.
