«Cool Air» by Howard Lovecraft

"Cool Air" is a short story by the American horror fiction writer H.P. Lovecraft, written in March 1926 and published in the March 1928 issue of Tales of Magic and Mystery.
The narrator offers a story to explain why a "draught of cool air" is the most detestable thing to him. His tale begins in the spring of 1923, when he was looking for housing in New York City. He finally settles in a converted brownstone on West Fourteenth Street. Investigating a chemical leak from the floor above, he discovers that the inhabitant directly overhead is a strange, old, and reclusive physician. One day the narrator suffers a heart attack, and remembering that a doctor lives overhead, he climbs the stairs and meets Dr. Muñoz for the first time.
The doctor demonstrates supreme medical skill, and saves the narrator with a combination of medications. The fascinated narrator returns regularly to sit and learn from the doctor. As their talks continue, it becomes increasingly evident that the doctor has an obsession with defying death through all available means.
