Doc Disinfectant

Crossing over quickly, Doc picked up a book, opened it and used it like pincers to pick up the strange scarlet missive. He carried it into the laboratory, and dunked it in a bath of concentrated disinfectant fluid, stuff calculated to destroy every possible germ.

"I've heard of murderers leaving their victims an envelope full of the germs of some rare disease," he told the others dryly. "And remember, it was a strange malady that seized my father."
