The Duel of Dr. Hirsch (The Father Brown Classics, Episode 15)

The Duel of Dr. Hirsch is a short story by Gilbert Keith Chesterton: M. Maurice Brun and M. Armand Armagnac were crossing the sunlit Champs Elysées with a kind of vivacious respectability. They were both short, brisk and bold. They both had black beards that did not seem to belong to their faces, after the strange French fashion which makes real hair look like artificial. M. Brun had a dark wedge of beard apparently affixed under his lower lip. M. Armagnac, by way of a change, had two beards; one sticking out from each corner of his emphatic chin. They were both young. They were both atheists, with a depressing fixity of outlook but great mobility of exposition. They were both pupils of the great Dr. Hirsch, scientist, publicist and moralist.
