Debra Charlotte Morgan (spelled Deborah in the novels) is a fictional character created by Jeff Lindsay for his "Dexter" book series.

Jeffry P. Freundlich (born July 14, 1952), primarily known by his pen name Jeff Lindsay, is an American playwright and crime novelist best known for his novels about sociopathic Miami Police Department forensic analyst and serial killer-killing vigilante Dexter Morgan.

The first book in the Dexter series, "Darkly Dreaming Dexter" (which Lindsay wanted to name "Pinocchio Bleeds" after his middle daughter suggested it but his publisher disagreed) was included on the original nomination list for the Mystery Writers of America's Edgar Awards in the Best First Novel category.

"Dexter" aired as a series on Showtime with the first season based on "Darkly Dreaming Dexter" and actor Michael C. Hall playing the character. The show eventually ran for eight seasons, though subsequent seasons had original storylines that departed from the plots of Lindsay's books. Lindsay had a cameo role in the tenth episode of the third season of "Dexter".
