Novel characters Darkly Dreaming Dexter characters The original Dexter novel, Darkly Dreaming Dexter, upon which the TV series' first season is based, includes the characters of Dexter, Debra (as Deborah), Rita, LaGuerta (first name Midgia), Batista, Doakes (first name Albert), Masuka (as Masuoka), Harry, Astor, Cody, Doris, Laura (although unnamed), Brian, Camilla Figg, Captain Matthews, Mike Donovan (as Father Donovan), Jamie Jaworski, and Nurse Mary (only referred to as "Last Nurse"), although some of them with different characteristics. Notably, Rita's ex-husband is referred to (although not by name), but the character himself does not appear.

The character is separated into two for the TV show, with Tony Tucci as the arena security guard and Neil Perry confessing to the killings.

Thus (with few exceptions) the characters from the subsequent novels (Dearly Devoted Dexter, Dexter in the Dark, Dexter by Design and Dexter Is Delicious) do not appear in the television series, nor do the characters introduced in seasons 2–5 appear in the books. Kyle Chutsky is a federal agent who appears only in the book series. He is a former Special Forces operative who worked alongside Sgt. Doakes. When a member of their old unit is found with all of his body parts removed, Doakes recognizes the work of his former comrade, Dr. Danco, and Chutsky is called in to help with the case. In the course of the investigation, Chutsky is captured by Dr. Danco. His little finger, on which he wears a distinctive ring, is amputated and mailed to
