Arrowsmith by Sinclair Lewis

In college Martin had been a "barb"-he had not belonged to a Greek Letter secret society. He had been "rushed," but he had resented the condescension of the aristocracy of men from the larger cities. Now that most of his Arts classmates had departed to insurance offices, law schools, and banks, he was lonely, and tempted by an invitation from Digamma Pi, the chief medical fraternity.

Digamma Pi was a lively boarding house with a billiard table and low prices. Rough and amiable noises came from it at night, and a good deal of singing about When I Die Don't Bury Me at All; yet for three years Digams had won the valedictory and the Hugh Loizeau Medal in Experimental Surgery. This autumn the Digams elected Ira Hinkley, because they had been gaining a reputation for dissipation-girls were said to have been smuggled in late at night-and no company which included the Reverend Mr. Hinkley could possibly be taken by the Dean as immoral, which was an advantage if they were to continue comfortably immoral.
