Jack breaks Danny's arm

Jack Torrance breaks his three-year-old son Danny's arm in a fit of rage after Danny spills beer on his manuscript, an act that becomes the defining trauma of the Torrance family and a recurring symbol of Jack's violent temper and alcoholism. The event, which occurs during the worst period of Jack's drinking, nearly destroys his marriage and leaves Danny with a permanent physical and psychological scar. It is the single most concrete manifestation of Jack's capacity for violence against his own family, a secret that haunts every subsequent relationship and decision, and a key that the Overlook Hotel later exploits to possess him.

Causes and Background

The breaking of Danny's arm is the culmination of Jack's escalating alcoholism and uncontrolled temper. At the time, Jack is a heavy drinker, and his writing is going badly. He has been working on a three-act play, The Little School, and one evening, while Jack is on the phone, Danny, then three years old, pours a can of beer all over the scattered pages of the manuscript, apparently to watch it foam. Jack returns to his study to find the papers ruined and Danny standing there in his training pants, grinning with pleasure at his work. The sight triggers an immediate and overwhelming rage. Jack later recalls that the words "see it foam" played over and over in his mind "like a single sick chord on an out-of-tune piano," completing the circuit of his fury.

The Act of Violence

Jack grabs Danny's hand and bends it to make him drop the typewriter eraser and pencil he is holding. Danny screams. Jack then whirls him around to spank him, his large adult fingers digging into the scant flesh of the boy's forearm and meeting around it in a closed fist. The sound of the breaking bone is described as a "clean sound with the past on one side of it and all the future on the other," like a breaking pencil lead or a small piece of kindling snapped over a knee. The snap cuts through Jack's red fog of rage, and he is immediately flooded with shame and remorse. He sees Danny's face drain of color and his eyes grow large and glassy, and he hears his own weak, drunken voice asking, "Danny, are you all right?"

Immediate Aftermath and Family Crisis

Wendy, hearing Danny's scream, rushes in and sees the peculiar angle of Danny's forearm, which no arm is meant to hang. She sweeps Danny into her arms, screaming, and dials the hospital. Jack stands stunned and stupid, and when his eyes meet Wendy's, he sees that she hates him. The incident nearly ends their marriage. Wendy later recalls that she had been pondering divorce for months, and the broken arm was the final push. She tells herself that the divorce is necessary for her son's sake, and that Jack is a lush with a bad temper who has accidentally or not accidentally broken their child's arm. The memory of Danny in his cast becomes a recurring, painful image for her, a symbol of Jack's destructive potential.

Long-Term Consequences and Recurrence

The broken arm becomes a permanent reference point in the family's history. Jack, in his moments of self-loathing, thinks of it as the worst thing he has ever done. He later admits to Dr. Bill Edmonds that he meant to do it, that "someplace inside I really did mean to do that to him. Or something even worse." The event is directly linked to Jack's decision to stop drinking, a promise he makes to himself in the aftermath. However, the trauma resurfaces throughout the novel. When Danny later stutters in a trance, Jack screams at him, "Don't stutter!"—a reaction that terrifies both Danny and Wendy, who sees it as a return of the old, violent Jack. The memory of the broken arm is also what Wendy immediately fears when she finds Danny catatonic on the stairs, and it is the accusation she hurls at Jack when she believes he has attacked their son again. The Overlook Hotel itself uses Jack's guilt and capacity for violence against his family, ultimately driving him to attempt to murder them with a roque mallet, a grotesque echo of the earlier, less fatal assault.
