A patient mentions his lost thumb took six months to grow back, and his doctor realizes something has gone very wrong with humanity.

Robert J. Martin's 1962 story opens on a routine booster-shot visit whose small anomalies hint at a large and disturbing change in the human body. Tense, idea-driven hard SF that lets its horror dawn through clinical detail. Read it for a quietly alarming golden-age tale where a doctor's chart reveals more than a patient bargained for.
