The following is a list of characters from the book and television series Ghostwriter.

The titular character of the series is an enigmatic figure. The mystery of Ghostwriter's true identity is never fully answered, although several clues are given during the course of the series in several of the cases (the following facts are from "Ghost Story", the pilot episode, unless otherwise stated):

• He was a man when he was alive, but is now a ghost.
• He wanted to protect "the children".
• He can only be seen by those to whom he reveals himself.
• He can read and feel emotions.
• He cannot hear.
• He communicates by writing.
• He cannot talk.
• He was alive before:
  1. the Federal Bureau of Investigation was formed (1908).^[1]
  2. Walt Disney became famous (after 1920).^[2]
  3. Elvis Presley (born 1935).^[3]
• He cannot see pictures.^[3]
• He wrapped around the Prison Ship Martyrs' Monument as if happy or familiar with it.^[3]
• He requires team cohesion in order to "survive". ("Get the Message")
• He can travel through time. ("Just in Time")
• He can travel across the Internet. ("Who is Max Mouse?")
• At one point, he remembers he was chased by dogs. ("A Crime of Two Cities")

The producers' intent was to reveal Ghostwriter to be "a famous 15th- to 16th-century writer, but not Shakespeare" at the end of the first season, although this eventually never happened.^[4]

D.J. MacHale, who wrote the pilot episode, stated: "If memory serves, Ghostwriter was supposed to be an ancestor of Jamal's, who was an escaped slave from the south who educated himself and learned the value of reading".

According to producer and writer Kermit Frazier: "Ghostwriter was a runaway slave during the Civil War. He was killed by slave catchers and their dogs as he was teaching other runaway slaves how to read in the woods. His soul was kept in the book and released once Jamal discovered the book".^[5]

When the show began, it was based around four main characters, all students at Zora Neale Hurston Middle School and Washington Elementary School in Fort Greene, Brooklyn, New York. The "team" later expanded to include six (later seven) active members, one MIA member, one member in Australia, two members in England, and three members in 1928.

To become a member of the team, a kid would have to be able to read the words that Ghostwriter manipulates. There was normally an induction ceremony for each new member that joined the team. At this ceremony, they would be given a special pen with a string to be placed around the neck so the members could write to Ghostwriter no matter where they happened to be and to note all of the clues in their investigations. When a team meeting was required, one of the members would use Ghostwriter to send out the message "rally", followed by the first initial of the member that was hosting the meeting (usually either Jamal, Alex, Lenni or Gaby). Alex, Jamal, and Lenni also came up with a special Ghostwriter handshake for the team.

Members of the team also use a casebook. A casebook is a binder with papers for noting all the suspects, evidence against them, and clues in their investigations, allowing the team to review them. Alex later coins the review under the term "rewind", which the team likes and it became their catch phrase. As Gaby said, "solving a case is like putting a jigsaw puzzle together, and the casebook is where (they) keep all the pieces". Basically, a casebook is an effective tool to "start piecin' the puzzle. Organizing stuff, getting it together". Ghostwriter would also read whatever was written within the casebook, and then help the team to find more clues. There is also another casebook especially made for Ghostwriter to help him figure out who he was.

Make a casebook to keep track of all the clues:

• Make a page for each suspect.
  • SUSPECT: Who might have done the crime?
  • EVIDENCE: Where was the suspect and why would he or she do it?
• Make a page for OTHER CLUES.
  • Write facts that may be important to help solve the case.^[6]

Jamal (portrayed by Sheldon Turnipseed) is level-headed and intelligent; the first person Ghostwriter reveals himself to and the de facto leader of the Ghostwriter team. In the first episode of the series, "Ghost Story, Part 1", seventh grader Jamal is cleaning out the basement of his family's brownstone with his father, Reggie Jenkins (portrayed by Samuel L. Jackson in the first three cases and Dean Irby afterwards) and his mother Doris Jenkins (portrayed by Elizabeth Van Dyke), when a spirit emerges from a book that has fallen on the ground and begins communicating with Jamal through words.

Jamal lives with his parents and his grandmother (portrayed by Marcella Lowery); his older sister Danitra is away at college. Midway through the second season, Jamal's young cousin, Casey, also comes to stay with the family. Jamal's interests include karate and science; he dreams to one day be "a scientist that performs experiments in outer space".

Lenni's father is a musician. Her mother died when Lenni was a young child. Midway through the series, Lenni's father begins to date a British woman named Sally. Though Lenni likes Sally very much (she was the one who introduced them), she has trouble coping with her father's new relationship.

Frank Flynn, Catherine Canellan, and Lucy Canellan lived in Jamal's house in 1928; all are the children of Irish immigrants. Catherine and Lucy's father, a physician, was Frank's foster father and mentor in medicine. Ghostwriter helps Frank because of his future importance as a cardiac surgeon and to Jamal's family. Catherine was with him when Ghostwriter appeared in front of him, and he later writes to Lucy to convince her to help Frank.

After the team helped prove his innocence, Frank eventually followed his mentor's footsteps to become a physician and worked at the Brooklyn Children Hospital. He was also a well-known philanthropist in the city who would help lower-class families who could not afford medical care.

He performed a heart surgery on Jamal's father, Reginald "Reggie" Jenkins, when Reggie was four years old. This was pivotal to the formation of the Ghostwriter Team because if Frank had not operated on Reggie, Reggie would have died during his childhood. As a result, Jamal would have never been born and Ghostwriter would never have met Jamal. This meant the other team members would never have met Ghostwriter and the team would never have been formed. Under a causal loop of time travels, the Ghostwriter Team is inadvertently responsible of shaping Frank's life as a physician and his eventual operation on Reggie Jenkins, Jamal's and his sister Danitra's births, their first meeting among each other as seen on the five-part pilot episode "Ghost Story", and other outcomes throughout the series because of the team's existence.

Frank and Catherine are married at some point after they have reached adulthood. Not only has Frank fulfilled his destiny as it should be, but Catherine also becomes a successful mystery novelist. Frank died on May 1, 1992, at the age of 76, a year before the team meets Catherine, and Lucy's fate is never revealed onscreen.

Frank, Catherine, and Lucy only appear in the episode "Just in Time". After that case ends, they are not seen or mentioned again. They were portrayed by Louis Todaro, Grace Johnston, and Stephi Lineburg, and the older version of Catherine was by Augusta Dabney.

Sam and Becky Wentwood live in the United Kingdom. Their parents own a bed and breakfast. They met Jamal and Ghostwriter while Jamal's family was vacationing in London. They only appear in the episode "A Crime of Two Cities". After that case ends, they are not seen or mentioned again. They were portrayed by Paul Francis and Candace Hallinan.

Other cast members include:

• Lt. Isaiah McQuade (Mike Hodge), a detective who serves as the Ghostwriter Team's police contact.
• Calvin Ferguson (Wil Horneff in "Ghost Story", Joey Shea thereafter) is a narcissistic peer of Alex, Jamal, Lenni, Rob, and later Tina at Hurston Middle School, serving as the Ghostwriter Team's enemy. Calvin is jealous of the team's numerous successes in solving their neighborhood's crimes since "Ghost Story", and is determined to learn their secret, even emulating their investigative methods.
• Jeffrey Baxter (Jon Hershfield), Calvin Ferguson's friend.

Jackson as Jamal's father Reginald "Reggie" Jenkins in the first three cases (later replaced by Dean Irby), Mark Linn-Baker, Julia Stiles, Max Wright, Spike Lee, Patricia Barry, Daisy Fuentes, Orlagh Cassidy, Judge Reinhold, Melinda Mullins, Annabelle Gurwitch, Robin Leach, Salt-N-Pepa, Madhur Jaffrey, Harry Connick, Jr., CeCe Peniston, David Patrick Kelly, Charles Mann and Bo Jackson.
