Dexter Morgan is the lead and title character of both the Dexter Novels and the Dexter Comics, all written by Jeff Lindsay.

Dexter is a charming forensic blood spatter analyst, who also happens to be a serial killer.

Lindsay's first novel, Darkly Dreaming Dexter, inspired the Showtime series DEXTER which generally followed its events throughout Season One. From Season Two onward, the series became a separate universe with new characters and events.

In the TV series, Dexter Morgan himself was far more "human." Over time, he began to discover the importance of friends and family, and experienced the feelings of love and grief.


Dexter is the adopted child of Harry Morgan and Doris Morgan, as well as the adopted brother of Deborah Morgan.

During his time at Coconut Grove High School, Dexter was bullied by a Cuban student known as Steve Gonzalez. After a pep talk with his father, Harry, Dexter attempted to make Steve pay for the abuse to the point of putting Steve on his table. However, Dexter was interrupted and was unable to kill Steve.

As a teenager, Dexter realized that he was uninterested in sex or dating and needed instruction by his father on how to interact with women.

As stated in Darkly Dreaming Dexter, after high school, Dexter completed his studies at the University of Miami.

When Dexter was 19, Harry fell ill of coronary disease and was confined to a hospital where Harry spotted First Nurse who was purposefully overdosing patients on morphine. Harry gave Dexter his permission to kill her. She was Dexter's first human victim.

Later, Dexter married Rita Bennett, who became Rita Morgan. He has a biological daughter named Lily Anne Morgan and two step-children, Cody and Astor Bennett.


Dexter is the title character of each of the books and, as such, is the main focus of each novel, mostly told from his perspective.

Near the end of the first book, Brian and Dexter meet in a shipping container similar to the one they were held in as children, and Brian recounts what happened. He says that one of the bodies they were surrounded by could have been their father for all they knew. Deborah is awake when Dexter arrives at the cargo container, and she learns of Dexter's hobby as a serial killer. After the death of Detective LaGuerta, Deborah begins to accept Dexter.

Dexter is forced to wear his "disguise" all the time because Sergeant Doakes is following him, trying to catch him in the act of killing someone. In desperation, Dexter tries to discover something about Doakes that might be useful in getting Doakes off his tail. However, he finds out very little. Dexter realizes that Doakes and Kyle Chutsky know each other after Doakes has Captain Matthews call in help from Washington when a still alive, dismembered body is found. Dexter learns from Deborah and Chutsky that Doakes served in a black-ops mission in El Salvador. He also learns about Dr. Danco, the man responsible for the mutilated body. When Chutsky himself is taken, Deborah pleads with Dexter to find him. Luckily for Dexter, his new friend - Luis Barba - understands his lizard brain, becoming Dexter's new side kick and student. Luis also helps with distracting Doakes. Not long after, Dr. Danco sends Chutsky's finger with the ring still attached. Dexter keeps the ring to give back to Deborah, but Rita finds it and believes that Dexter is meaning to propose to her. Dexter, Deborah, and Doakes work together to find members of the El Salvador unit. During a chase through Miami, Dr. Danco runs Dexter and Deborah off the road. Dexter and Doakes set up a trap to lure the doctor but it enables Dr. Danco to capture Doakes. Dexter traces Doakes' cell phone to an alligator farm where he finds Chutsky and helps him escape. However, Dr. Danco still has Doakes, and then Dexter himself is captured by Dr. Danco. It is only the timely arrival of Deborah and Chutsky that saves him.

It is revealed through third person narrative of an entity referred to as "IT" that the Dark Passenger is an independent agent inhabiting Dexter, rather than a deviant psychological construction. Later, Dexter realizes the Dark Passenger is related to Moloch, a Middle Eastern deity worshiped in Biblical times. The Dark Passenger is one of Moloch's many offspring; Moloch had many children (formed through human sacrifice), and learned to share its knowledge with them. Eventually, there were too many, and Moloch killed the majority; however, some of them escaped into the world. In the novel, Dexter learns of the Dark Passenger's true nature when it briefly "leaves" him, frightening him into researching possible reasons for its existence. Dexter comes to accept his role as stepfather to both children very seriously, albeit in his typical fashion. For example, while on a stakeout, he begins to wonder if Cody had brushed his teeth before bed and if Astor had set out her Easter dress for picture day at her school. These thoughts distract him from hunting an intended victim, which thoroughly annoys him.

Lindsay deviates from the supernatural subtext of the previous book, and focuses on psychological suspense. The book opens in Paris, with Dexter and Rita on their honeymoon. While visiting an art gallery, Dexter and Rita are introduced to the concept of body parts being used as art by an avant-garde performance piece called "Jennifer's Leg" in which the artist amputates her own limb. When they return to Miami, Dexter crosses paths with two new enemies; a suspicious homicide detective, and a new serial killer in town targeting tourists. Thought to be one of the killers displaying corpses in public, Dexter murders Alex Doncevic. He later finds out that Doncevic was not a killer. He and Brandon Weiss were just stealing corpses of already dead people from the morgue and displaying them with decorations. Doncevic's death causes Brandon to become an actual serial killer. Alex is the first somewhat innocent victim of Dexter.

Dexter finally decides to give up his dark hobby after witnessing the birth of his daughter Lily Anne. He believes that for the first time in his life he is feeling genuine emotion. Meanwhile, Dexter becomes reacquainted with his brother Brian, who knows about Dexter's child. Dexter struggles with the burden of feeling emotions while attempting to give up his serial killing life. At one point, Dexter indulges himself after getting angry, but he immediately vows not to do it again. At the end of the novel, Dexter sets out to kill Bobby Acosta, the son of a city commissioner who gets away with murder and cannibalism, after Deborah realizes that Bobby's father will simply pay for the entire thing to disappear.

Dexter is spotted while performing his Hobby. This person soon begins to torment Dexter while also beginning their own killing spree. Dexter finds himself in a game of Cat and Mouse, as Dexter tries to find out his tormentor's Identity.

When movie star, Robert Chase, and a group of actors descend on the Miami Metro Police Department for "research," Chase becomes fixated on Dexter Morgan, the blood spatter analyst. Chase shadows Dexter's every move, trying to learn what makes him tick. This makes it difficult for Dexter to continue his favorite pastime of hunting down killers who've escaped prosecution.

Dexter is arrested on charges of murder. He has lost everything -- including his wife, his kids, and the loyalty of his sister. Now completely alone, Dexter faces a murder charge (for a crime, ironically, he did not commit). His only chance for freedom lies with his brother, Brian, who has a dark plan to prove Dexter's innocence... but the stakes are deadly.

Freshly arrived to the airport, Dexter is greeted by Sergeant Shawna Wiggs, who escorts Dexter to the Canberra Police HQ. They begin to investigate the murders of immigrant Asians.

Main article: Dexter's Kill List (Novels/Comics)

Attempted Victim

  • Debra Morgan - Influenced by his newfound biological brother, Brian, Dexter reluctantly attempts to kill his adoptive sister, Deborah. However, in a rapid change of mind, he does not go through with it, against his brother wishes.


  • Interesting side note, Dexter has never killed a main antagonist in the novels. While he indeed killed a main antagonist, Steve Gonzalez, this happened in the comic books.
  • Author Jeff Lindsay, in talking about Double Dexter refers to Dexter as a man you shouldn't be seduced by, "Some believe that Dexter cares about justice. Dexter doesn't care about justice, he cares about killing." This differentiates the serial killer in the TV series that appears to have some sense of justice (such as his actions in Season Two) from the one in the novels, where he is more inhuman.
  • Despite the fact that Michael C. Hall's likeness cannot be used in the comics, the cover of issue 5 clearly resembles Dexter, with the hairstyle and face traits of his television counterpart.
