 The series premiered on April 11, 2010, and concluded on December 29, 2013, comprising four seasons and 36 episodes.

The Courir de Mardi Gras (] ] ) is a traditional Mardi Gras event held in many Cajun communities of south Louisiana on the Tuesday before Ash Wednesday.
 Courir de Mardi Gras is Cajun French for "Fat Tuesday Run".
 The rural Mardi Gras celebration is based on early begging rituals, similar to those still celebrated by mummers, wassailers and celebrants of Halloween.
 As Mardi Gras is the celebration of the final day before Lent, celebrants drink and eat heavily, and also dress in specialized costumes, ostensibly to protect their identities.
 Popular practices include wearing masks, capuchons, and costumes, overturning social conventions, dancing, drinking alcohol, begging, feasting, whipping, etc.
 Because of violent activities associated with the Ku Klux Klan, Louisiana has a state law prohibiting the wearing of hoods and masks in public.
 Mardi Gras is one of the few occasions when exceptions are allowed, as are Halloween celebrations and religious observances.
 Two HBO series (the crime drama "True Detective" and the post Hurricane Katrina themed "Treme") make reference to the tradition.

 The series features Powers Boothe as Raymond Chandler's title character, and was the first drama produced for HBO.
 It was an early example of the uncompromising commitment to authenticity HBO would become known for in period pieces, recently showcased in "Rome" and "Deadwood", the latter of which also featured actor Powers Boothe.
 Unlike other modern incarnations of the Marlowe character, the HBO series kept the show set in the 1930s, true to the original Raymond Chandler stories.
