Question: Which Pulitzer Prize winning author was featured in a 2014 documentary about Edward Snowden? 
Context: Lew Archer is a fictional character created by Ross Macdonald.  Archer is a private detective working in Southern California.  Between the late 1940s and the early 1970s, the character appeared in 18 novels and a handful of shorter works as well as several film and television adaptations.  Macdonald's Archer novels have been praised for building on the foundations of hardboiled fiction by introducing more literary themes and psychological depth to the genre.  Critic John Leonard declared that Macdonald had surpassed the limits of crime fiction to become "a major American novelist" while Pulitzer Prize winning author Eudora Welty was a fan of the series and carried on a lengthy correspondence with Macdonald.  The editors of "Thrilling Detective" wrote: "The greatest P.I. series ever written?  Probably."

The Elizabeth Bishop House, also known as the Bulmer House, is an historic single-family house that today is used as an artists' retreat in Great Village, Nova Scotia.  The house is associated with Pulitzer Prize winning author Elizabeth Bishop who in her youth lived in the house each summer with her maternal grandparents, William Brown Bulmer and Elizabeth (Hutchinson) Bulmer.  Bishop based many of her stories (such as "In the Village") and poems (such as "Filling Station") on aspects of Great Village and Nova Scotia.  Although the Bulmers bought the property in 1874, it is not known when it was built.  On May 21, 1997, the Bulmer House was recognized as a Nova Scotia Provincially Recognized Heritage Site for its connection to Elizabeth Bishop and her writings as well as for its architectural significance; it is a good example of a typical 1 ⁄ -storey Classical Revival dwelling dating from between 1800 and 1850, a type common to rural Nova Scotia.
