Meredith Barrett or Merry, aged 23, is the narrator of the novel, and the only surviving member of her household following the deaths of her parents and sister when she was eight. A Head Full of Ghosts uses verisimilitude, a literary device which aims to add a sense of realism and credibility in fiction. It gives the appearance of authenticity by using posts from a horror blog that Merry writes under the pseudonym “Karen Brissette.”
Merry is a quintessential unreliable narrator: She was a child when the events she recounts took place, has rewatched her family’s “documentary” The Possession countless times, scoured the Internet and other resources to discover everything she can related to the case, marinates in her obsession with horror, and freely admits that her memory is clouded and confabulated. Her memory appears to be selective, and she curates how and what she shares with Rachel, frequently excusing herself from blame for any inconsistencies due to her memory. One of the central uncertainties of the novel is the question of whether, at any given time, Merry herself believes what she is claiming.
As an eight-year-old, Merry is demanding, obnoxious, selfish, obstinate, and immature, beyond the scope of what should be expected from a child her age. She cannot stop herself from talking, and requires the undivided attention of others around her at all times when she is not attempting to eavesdrop on them or violate their privacy. Her emotions and cognitive state may have been impacted as a result of the horrific events which occurred within her family.
At the same time, her personality traits may also be independent of events. At 23, Merry demonstrates very little personal growth. She manifests a lack of empathy; is unable to perceive herself as anything other than the focal point of any given situation; has a flippant, jocular attitude toward what others consider “ghoulish” or upsetting; and has little awareness of how others perceive her. She is not a previously well-adjusted child whose life was decimated by tragedy. Instead, Merry is the product of a “dysfunctional” family, and seems to have changed very little despite watching her parents and sister die of potassium cyanide toxicity.
Merry believes herself to be a protagonist and heroic survivor. Instead, she functions as a deuteragonist, or person who is second in significance, to her sister Marjorie. Merry regularly refers to Rachel’s work, comprised of Rachel’s extensive research and interviews, as “our” book. She is mistakenly under the impression that she will be the focal point of the text. As the novel progresses, Rachel gradually loses trust and faith in Merry’s version of events, admitting that Merry’s decisions to obfuscate, manipulate, and engage in deception leave her uncertain how to proceed.
Marjorie Barrett, age 14, is the protagonist of A Head Full of Ghosts. Through her, the novel explores a key theme, Ordinary Human Malignancy Is the True Horror. Marjorie’s experience with escalating symptoms of mental illness and her parents’ failure to protect and help her are the ultimate tragedy of the novel. The narrative only reveals what Marjorie purportedly shared with Merry; it is through this lens that her experience is conveyed. Initially, Marjorie confides in her sister that she is convinced that her bedroom is rearranging and redecorating itself on its own, though she cannot pinpoint the changes and has never witnessed this happening. Increasingly, voices belonging to those she refers to as “them” speak to her; they suggest “disturbing” ideas, are frightening in their hopelessness, and nurture mistrust and dread.
Marjorie resents attending treatment with Dr. Hamilton and the effects of the medication she is prescribed; it is hinted that she is often noncompliant with her dosages. Marjorie is convinced that Dad poses a significant threat to their entire family, and tries to get Merry to understand that. When the “documentary” film crew arrives to record her exorcism, Marjorie claims that she intentionally ramped up her symptomology in hopes that an event like this would result in a financial windfall for their family, or the possibility that her father would be discovered to be a danger to them.
Despite the fact that many of Marjorie’s beliefs and experiences are not grounded entirely in reality, she is the most perceptive and intelligent member of her family. She maintains a measure of control over herself and the situation even as she experiences fear and mental illness.
Through Marjorie, the novel explores another key theme, Sacrifice and Exploitation of the Vulnerable. The “documentary” sensationalizes Marjorie’s mental illness. After jumping from the balcony, the state becomes involved but fails to protect her. Marjorie’s sense of impending doom increases despite twice-weekly visits from her psychiatrist. The appearance of a jar of potassium cyanide in the basement in conjunction with research on men who harm their families leads Marjorie to the conclusion that Dad plans to harm them all.
Merry claims that Marjorie’s plan was to introduce the poison to their family’s dinner so that they could incapacitate their parents and seek help from the police. Instead, Marjorie eats the poison herself, suggesting she was deeply unhappy and wanted to die by suicide. Her toxicology report noted that none of her antipsychotics were present in her system at the time of her death.
Merry claims that her sister had schizophrenia, though it is unclear whether Merry assumed this or if Marjorie was professionally diagnosed. Marjorie’s actions seem to indicate she experienced psychosis if in fact she intended to kill herself and her parents. Many who experience paranoia and psychosis believe that they must destroy an imminent threat against them, and often themselves, in order to protect others and escape a terrible fate.
John Barrett considers himself to be the head of his household. However, he fails to embody the traditional responsibilities of such a role.
Directly out of high school, he was employed at a local toy factory, where he worked for 19 years until it closed. When the novel begins, he has been unemployed for 18 months, exasperating his wife, as he has not found gainful employment, nor does he help her with housekeeping, chores, or the more stressful demands of parenting their children. He has a temper and his parenting style, which consists of intimidation and yelling, has deteriorated in recent months.
He has been a lapsed Catholic for several years. When his daughter gets sick, he begins attending a local church and lies to his wife, claiming that he is looking for work. He goes against his wife’s wishes, taking their daughter to see his priest without asking. Having not seen the progress he expected with Marjorie’s psychiatric treatment, he becomes convinced that a holy intervention is necessary. He eagerly embraces an exorcism from the Catholic church, relying on Father Wanderly’s advice. He pressures and wears down his wife until she acquiesces, and even when she vehemently objects to elements of their approach, he bulldozes her concerns.
As his daughters watch, his emotional state is impacted, even after the funding from The Possession solves his financial problems. He becomes violent with protestors outside his house and is combative with his wife. He is zealous in his religious beliefs despite little understanding of Catholicism and lack of comprehension of the Bible. When Marjorie’s exorcism fails, he threatens to sue the church and the production company. He sees himself as entirely without blame, a person to whom things happen instead of someone who plays a part in what occurs in his life.
His fingerprints are found on the jar of potassium cyanide that Merry and Marjorie integrate into the spaghetti sauce. This suggests that Marjorie’s suspicions about him may be right—that he shared characteristics with other fathers who kill themselves and their families, and may have done the same to his. At the same time, it could also indicate that someone else put his fingerprints on the jar, or that they were there for benign reasons.
Sarah Barret or Mom, along with Marjorie, bears the greatest burden in A Head Full of Ghosts. Mom works full time as a bank teller. She is committed to pursuing and participating in qualified psychiatric treatment for her daughter, despite the financial strain that it is placing on their family. She is frustrated with her husband for not finding a job, especially as foreclosure is looming and their daughter seems to need more intensive, and therefore expensive, care. She frequently expresses her indignation that others in the house don’t offer to help with housework, especially as she works 40 hours a week.
She does her best to be patient with Merry. Where her husband thinks that Merry is funny, Mom recognizes that Merry doesn’t seem to care about crossing others’ boundaries. Mom tries to be kind but strict in reminding Merry that people have the right to privacy and that she does not have the right to demand attention from them. She tries to help Merry understand what is happening to Marjorie, while attempting to shield her from the most serious and frightening aspects of Marjorie’s condition.
Subtle changes in her behavior, which soon become more pronounced, indicate how she is being impacted. She used to smoke outside; now she smokes in the house. She also begins drinking regularly and is less patient with Merry and the camera crew. Though she is an atheist, Mom eventually acquiesces to Dad’s demand to rely primarily on the church’s guidance and pursue an exorcism for their daughter.
At the same time, she advocates for retaining Dr. Hamilton’s care of Marjorie. It is likely that, given their dwindling financial circumstances, Mom decides that she will allow the exorcism— not because she thinks it will be effective, but because it will save them from destitution. Later, as the situation becomes more dire, Mom repeatedly expresses her doubts and regrets. She tries to advocate for her daughter, insisting that Marjorie still has control and can stop the proceedings at any time.
She and Marjorie appear to share a special bond. As the two most mature people in the house, they seem to understand one another, even though Marjorie’s illness and her newfound adolescent sense of independence create frequent disagreements and rifts between them.
