What's inside (8 sections)
I picked up The Exorcist because I had seen the 1973 film years ago and assumed I knew the story. Cold room, spinning head, priests, pea soup. That was about the size of it in my memory. Reading William Peter Blatty's novel, first published in 1971, was a different experience. The HarperTorch edition I read runs 385 pages, and a lot of those pages are not about shocks at all. They are about a tired priest who misses his mother, an actress who cannot protect her daughter, and an old archaeologist who has seen something bad before. I finished it late at night with the house quiet and I did not sleep well, not because of one scene but because the book is patient about dread.
The basic shape is simple. Chris MacNeil, a successful actress in her early thirties, is in Washington for a film shoot. She rents a house in Georgetown with her twelve year old daughter Regan, plus two live in helpers, Sharon Spencer and Karl. Regan starts hearing scratching in the attic. She plays with a Ouija board and talks about a friend named Captain Howdy. Her personality shifts. Then her body changes in ways doctors cannot explain. After hospitals and tests fail, Chris turns to priests. Father Damien Karras, a Jesuit psychiatrist at Georgetown University, is asked to look at the case. Father Lankester Merrin, older and ill, is brought in for the rite itself. What follows is slow, ugly, and sad. The pace stays steady rather than frantic, which makes the bad parts hit harder when they arrive.
An actress, a rented house, and Captain Howdy
Chris MacNeil is not the usual horror mother. She is divorced, working long hours on a film directed by Burke Dennings, a loud British man who drinks too much and swears at everyone. Chris is capable and funny and openly atheist. She loves Regan in a practical way. She remembers lines, hits marks, argues with the studio, then comes home and tries to be present. Sharon helps with schedules. Karl and his wife Elvira handle cooking and cleaning. It reads as a busy but stable home, the kind where money solves logistics but not fear.
Blatty takes time to set up the Georgetown house. Brick, narrow stairs, Regan's bedroom upstairs with a window that later matters a great deal. The attic noises start small. Rapping. Scratching. Chris thinks rats. Karl checks. No rats. Regan says her bed shakes at night. She complains that it moves and will not stop. Chris at first treats it as nerves. A child in a new city while her mother works nights. That feels reasonable.
Then there is the Ouija board. Regan says she talks to Captain Howdy through it. At first the answers are childish. Questions about school, about her father in Europe, about horses. Chris is mildly amused. Sharon is less so. The board spells odd things. Regan's voice changes when she talks about Howdy. She uses words she should not know. She wets the bed after years of not doing so. She becomes rude in a pointed way that does not sound like a twelve year old testing limits.
One early scene that stayed with me has Chris coming home to find Regan asleep with the board and asking about it in the morning. Regan is vague. She smiles in a way Chris does not recognize. Blatty does not push it. He lets Chris rationalize, which is what a parent would do. Move her to a bigger room. Spend more time together. Call her father. It is only when Regan's face changes, her voice drops, and her strength spikes that rationalizing stops working.
Burke Dennings is part of this section too. He likes Regan and teases her. He directs Chris in scenes about student protests, which dates the book. His death later lands because Blatty made him alive here.
Doctors, tests, and no answers
The middle of the book is medical. Chris takes Regan to doctors, then to specialists, then to a hospital for observation. Blatty describes the process in detail. Blood work. Spinal tap. EEG. Psychiatric interviews. The famous arteriography scene, where dye is injected to image vessels in the brain, is written with clinical care. Regan screams. Blood spurts. Chris watches from behind glass and nearly faints. The doctors speak in careful terms. Temporal lobe disturbance. Psychomotor epilepsy. Hysteria with conversion symptoms. They suggest Librium and rest.
Nothing helps. Regan worsens. Her face swells. Sores form around her mouth. She curses in a low rasp, in languages she never learned. She throws a heavy dresser with impossible force. During a small party Chris holds for the film crew, Regan comes downstairs, urinates on the rug, and tells an astronaut guest he will die up there.
Blatty writes these scenes without winking. He stays close to Chris. Her money gets the best doctors, but it cannot buy a name for what is happening. One night Regan begs for help in her own voice, small and scared, then shifts back into something else that laughs.
This medical stretch will test some readers. Consultations stack up and the language gets technical. I found it effective because it closes off escape routes. When a senior doctor finally says, quietly, that exorcism has helped in cases like this through suggestion, Chris is furious and then, days later, desperate enough to call the university.
The strength of this section is Chris herself. She does not convert. She does not suddenly pray. She asks for help because her daughter is dying in front of her.
Karras and Merrin
Father Damien Karras is the heart of the novel. He is in his mid thirties, a Jesuit priest and trained psychiatrist, working with students and patients at Georgetown. He is strong from boxing, smart, kind, and exhausted. His mother, an old immigrant woman who speaks little English, lives alone in New York. Karras placed her in a hospital and carries guilt about it. When she dies while he is in Washington, he cannot get there in time. He dreams about her. He hears her voice. He wonders if he failed her for wanting a life of study instead of staying near.
Blatty gives Karras long interior passages. He prays and feels nothing. He counsels others and cannot counsel himself. His superior, Father Dyer, a younger priest who loves movies, tries to pull him out of gloom with humor.
Father Lankester Merrin enters from a different direction. The prologue finds him in northern Iraq, at an archaeological dig near Nineveh. He is in his seventies, ill with heart trouble. Workers uncover a small statue of Pazuzu, a winged demon king. Merrin stares at it and feels fear he thought he had put away. He has faced this before in Africa, years earlier, in an exorcism that nearly killed him.
I loved how Blatty keeps Merrin distant for a long stretch. We get letters. We get other priests talking about him. When he finally arrives in Georgetown, he is frail and calm. Karras looks at him and worries the old man will not survive stairs, let alone what is upstairs.
The contrast drives the book. Karras has training and doubt. Merrin has experience and belief worn down to bone. Karras wants a psychiatric explanation because he is a psychiatrist. Merrin wants Karras to accept that explanation is not the same as cure. Their early meetings are careful. Merrin asks about Karras. Karras deflects. Merrin waits. It is a portrait of two tired men circling a house they both dread entering.
Burke Dennings, Kinderman, and the turn
Burke Dennings dies on the steps below the MacNeil house. His body is found twisted at the bottom of the long outdoor stairs that drop toward M Street. At first it looks like a fall after drinking. Kinderman, a police lieutenant with a rumpled coat and a habit of humming and asking odd favors, investigates. He asks Chris about Burke. He asks Sharon about comings and goings. He asks Karras about missing Mass. He is polite to the point of comedy, offering candy, apologizing for bothering people, then asking one more question that cuts.
Kinderman matters because he brings an outside eye. He notes that Burke's head was turned almost around. He notes that Karl, the housekeeper, looks suspicious on paper, though Karl is loyal and scared rather than guilty. His scenes with Dyer at the movies, talking about grief while eating popcorn, are among my favorites.
Regan's condition sharpens after Burke's death. She knows things she should not know. She repeats phrases from Karras's dead mother in a guttural voice. Sharon cannot stay in there long. Chris barely sleeps. She tells Karras she will do anything.
Karras visits and watches. He records. Part of him still looks for fraud. Regan, in a changed voice, describes his mother's last days in detail he never told anyone. That breaks something in him. He goes to his superiors and says the criteria for exorcism may be met. Permission is sought. Merrin is named as exorcist. Karras is named as assistant. Merrin tells Karras not to listen, not to argue, not to engage beyond the rite.
This is also where Blatty leans into theology. Why would God allow this. Why a child. Merrin's answer, when it comes, is spare. The point is to make those around her doubt love itself. I found those pages heavy but honest.
The rite
The exorcism takes up the last stretch and Blatty writes it as work, not fireworks. Merrin and Karras enter Regan's bedroom, now cold enough that breath shows. Merrin sets out the stole and ritual book and begins in Latin. Karras answers. Regan screams and laughs and vomits. The bed lifts and slams.
What makes it frightening is the talk. It uses Latin back. It brings up Karras's mother again, begging in her voice, asking why he left her alone. Karras shakes. Merrin tells him to keep praying, not to converse.
Blatty stages the rite in rounds. They leave, rest, return. Hours pass. Sharon and Chris wait downstairs. Kinderman waits outside in the street.
Merrin dies in the room. His heart gives out after strain and cold and age. Then the voice turns fully on Karras, mocking him as a failed son and a failed priest. Karras invites it into himself. He shouts to take him instead and throws himself through the window. He falls down the same stone steps where Burke died. Dyer reaches him in the street and gives last rites. Karras dies. Regan lives.
I had remembered the film's version of this and expected more noise. On the page it reads as bleak mercy. Karras, who felt he abandoned his mother, refuses to abandon Regan.
The coda is quiet. Chris and Regan prepare to leave Georgetown. Regan sees Dyer's collar and kisses his cheek without knowing why. Kinderman and Dyer strike up a friendship. That refusal to tie it shut is the bravest choice in the book.
What held up and what wore me down
Three things held up. First, the sense of place. Georgetown in winter, the university, the stairs, the hospital corridors, Iraq at the start with heat and dust. Second, the people. Chris is sharp and loving without being saintly. Karras is sad without being weak. Kinderman could have been comic relief and instead becomes moral weight.
What wore me down was real too. The procedural middle drags if you do not care about medical detail. Pages of consultation notes and church bureaucracy slow the story right when Regan is suffering. The theology talk gets thick. Blatty was a Catholic writing about belief from inside, and at times characters speak in essays rather than in voices.
Readers should also know the book is graphic. The crucifix scene, the vomiting, the language, the wounds. Blatty does not look away. Some of it serves the point that this thing hates bodies and loves shame. Some of it will simply disturb, especially around a child. If you are sensitive to medical scenes, this will be hard.
I closed the HarperTorch edition thinking less about Pazuzu than about Karras visiting his mother and feeling he had failed her. That guilt is the engine. The 1973 film by William Friedkin follows this closely, but the novel gives you more of the interior cost. If you want fast scares, this may feel slow. If you want horror that sits with grief and belief until both ache, it still works more than fifty years after 1971.
FAQ
Who performs the exorcism in The Exorcist?
Father Lankester Merrin leads the rite with Father Damien Karras as assistant. Merrin has faced possession before in Africa, while Karras is a Jesuit psychiatrist doubting his own faith.
How is the novel connected to the 1973 film?
William Friedkin's 1973 film adapts Blatty's 1971 novel closely, keeping Chris, Regan, Karras, Merrin, Kinderman, and Burke Dennings. The book gives more medical detail and interior monologue than the film can show.
Why does Chris turn to priests?
Doctors run blood work, EEGs, spinal taps, and arteriography without finding a cause. When a physician mentions exorcism has helped similar cases through suggestion, Chris asks Georgetown University for help.
