For 10 points, identify this mysterious author of The Treasure of the Sierra Madre.
One of this man's recurring characters was introduced in his first novel, The Cotton-Pickers and later appeared a third time in The Bridge in the Jungle. That character made his most famous appearance in a novel by this man in which he is shanghaied into serving on the Empress of Madagascar after earlier being stranded in Antwerp and forced to take a job as a drag man aboard the Yorikke. The most famous novel by this creator of Gerald Gales and author of The Death Ship stars the prospectors Curtin, Howard, and Fred C. (*) Dobbs, the latter two of whom are eventually caught and executed by the Federales. The 1948 John Huston adaptation of that novel by this man popularized a line he'd originally written as "In fact, we don't need badges. I don't have to show you any stinking badges!" He may be synonymous with his ostensible agent Hal Croves, while others think his true identity is Otto Feige or Ret Marut.
