Grim (Max's Grandfather)

Grim fears Max will repeat Killer Kane's violence because Kane — a man of similar large build — murdered Grim's own daughter, Max's mother. Unable to fully separate Max's imposing physical frame from the memory of what Kane did, Grim's protectiveness is shadowed by the terrible knowledge that he could not prevent that original crime. His guardedness is less about distrust of Max himself than about the trauma of losing his daughter and his dread of history repeating.

Grim and Gram are married co-guardians of Max who function as a complementary unit. Where Grim tends to tighten under pressure and express love primarily through vigilance, Gram is warmer and more openly nurturing. Grim frequently defers to Gram's steadiness when his own anxiety about Max or Killer Kane threatens to overwhelm the household, making their partnership a just-sufficient — if imperfect — safety net for their grandson.

Grim responds with frantic, desperate action — coordinating urgently with police and enduring what the novel frames as the worst hours of his life. The crisis strips away his habitual emotional guardedness and proves conclusively that his constant worry is rooted in deep love rather than indifference. Kane's Christmas Eve escape is the literal realization of the nightmare Grim has been bracing for since the story's opening pages.

Max lives in "the down under," a basement room, which reflects Grim's profound ambivalence toward his grandson. Grim keeps Max close — under the same roof — yet at an emotional and physical remove, unable to fully integrate him into the family's warmth. The arrangement quietly embodies Grim's inability to separate Max from the threat he associates with Killer Kane, making the living space itself a symbol of intergenerational trauma.

Grim begins by watching Kevin's visits with visible suspicion, uncertain what to make of the eccentric, disabled boy drawing Max out of isolation. Over time, however, he observes that Kevin's friendship unlocks something genuinely good and gentle in Max, and his resistance softens into grudging acceptance. He never becomes Kevin's champion, but this concession is significant for a man who does not lower his guard easily.

At the novel's close, Grim gently encourages Max to write down his memories of Kevin after Kevin's death. It is the most quietly significant gesture Grim makes — an act of faith in Max's mind and heart, and a recognition that his grandson has something worth preserving. The encouragement is also structurally crucial: it provides the entire novel's narrative frame, meaning Grim's trust directly produces the story the reader has just read.

Grim is neither a villain nor a warm patriarch — he occupies the uncomfortable middle ground between the two. His fear that Max carries Killer Kane's violent nature creates real emotional distance and functions as a kind of inherited harm, yet that same fear is born entirely from love and loss. Philbrick presents him as an imperfect but sturdy safety net: a man haunted by a murder he could not prevent, doing his flawed best to prevent whatever comes next.

Grim begins the novel in a posture of defensive anxiety, keeping Max at a physical and emotional remove. His trust loosens incrementally: Kevin's friendship offers early evidence that Max is not his father, and the Christmas Eve abduction crisis dissolves Grim's guardedness into something raw and honest. By the end, his encouragement for Max to write marks a full transition — from fearful warden to genuine supporter of Max's inner life.
