There are several tales about the origin of “the third degree,” a saying commonly used for long or arduous interrogations. One theory argues the phrase relates to the various degrees of murder in the criminal code; yet another credits it to Thomas F. Byrnes, a 19th-century New York City policeman who used the pun “Third Degree Byrnes” when describing his hardnosed questioning style. In truth, the saying is most likely derived from the Freemasons, a centuries-old fraternal organization whose members undergo rigorous questioning and examinations before becoming “third degree” members, or “master masons.”
