Emile and the Dutchman — Joel Rosenberg

Emile and the Dutchman were made for each other, though neither would ever admit it. They compliment each other perfectly, covering each other's weaknesses and amplifying each other's strengths. They make the best team in the Thousand World Contract Service.

They are in the business of making first contact with alien species. They hold the power to welcome a friendly species into the galactic community or to completely shut off a hostile species. What constitutes `friendly' or `hostile' is completely dependent on the interpretation of Emile and the Dutchman.
