Peter Murdoch: Rival, Reluctant Companion, and Sacrificial Hero in Katabasis
Overview of Peter Murdoch
Peter Murdoch is a fellow Cambridge postgraduate in analytic magick, an intellectual prodigy who becomes Alice Law's fiercest rival and later her reluctant companion on a journey to Hell. Beneath his confident, blithe exterior, Peter hides a chronic illness (Crohn's disease, which he calls "the Beast") and carries secret guilt over his role in Professor Jacob Grimes's death. His arc moves from competitive detachment to deep vulnerability, culminating in a self-sacrifice that saves Alice and redefines their relationship. This analysis distinguishes between explicit facts from the Katabasis text and interpretive readings of Peter's character.
Plot Role and Motivations
Peter enters the story when he discovers Alice's pentagram for descending to Hell and insists on joining her. His official reason is practical—he claims she will need help navigating the courts and carrying supplies—but deeper motivations emerge over time. He has been researching the underworld independently and feels responsible for Grimes's death: he carelessly proofread a paper containing lethal pentagrammic errors, leading to an explosion that killed multiple people. Peter also intends to retrieve Grimes's soul, partly to atone for his own negligence and partly because he secretly loves Alice. He plans to ask her to sacrifice him in an exchange for Grimes—offering himself as the price—rather than trading her soul, as she initially fears.
Traits Shown Through Actions
Peter's genius manifests in his quick mastery of magical theory and his ability to alter Alice's pentagram perfectly (Chapter One). He is unfailingly polite but oblivious to social norms, often rambling about philosophical problems rather than focusing on immediate tasks. His physical vulnerability appears during the climb of the bone wall in Chapter Three: despite suggesting the climb theoretically, he suffers a panic attack due to his fear of heights and must be talked down by Alice. This moment reveals hidden fragility beneath his confident exterior.
Peter's emotional withdrawal after their intense collaborative project (Chapter Thirteen) shows his tendency to pull away when intimacy threatens his carefully guarded independence. His later confession in Chapter Twenty-Three that he never planned to betray Alice—that he instead wanted her to sacrifice him—reveals a deep capacity for self-sacrifice driven by guilt and love. His chronic illness, revealed in Chapter Twenty-Two, explains his lifelong determination to hide weakness and his fear of being seen as dependent.
Chronological Arc
First Year at Cambridge: Peter meets Alice at a departmental tea. They bond over sharing Grimes as an advisor and later work late nights together in the lab, developing a private language and falling into an intense intellectual and emotional bond. Alice realizes she is falling in love. When the project ends, Peter inexplicably withdraws, offering only cold politeness.
Two Years Later (Present): Peter discovers Alice's descent plan and insists on accompanying her. During the journey through Hell's courts, their rivalry resurfaces—they argue over maps, time limits, and strategy. Peter's hidden illness and guilt are slowly revealed. In the Court of Desire, Alice reads his notebook and misinterprets his plan as intending to trade her soul.
The Betrayal at the Weaver Girl's Test: Alice, fearing betrayal, chooses the green apple (self-preservation) while Peter chooses red (together). This fractures their partnership.
Confession and Sacrifice: Trapped in the Escher illusion of the Violence court, Peter admits his true plan—to ask Alice to sacrifice him. He then activates the sacrifice himself, cutting his arm and chanting to send Alice out alone, giving his life to save hers.
Resurrection and Reunion: Alice later destroys Grimes's shade and uses the exchange to resurrect Peter. They ascend from Hell together, their relationship transformed.
Relationships: Alice and Peter
The relationship between Peter and Alice is the emotional heart of Katabasis. It evolves from rivalry to deep friendship to romantic love, though both conceal their feelings. Peter's withdrawal after their first collaborative project wounds Alice deeply, and she never fully trusts him again until his confession. Their shared abuse under Grimes—his theft of Peter's research, his sexual assault of Alice—bonds them in trauma. Peter's sacrifice is the ultimate expression of his love, mirroring the trust-and-betrayal themes that run through their journey.
Key Decisions and Consequences
- Deciding to join Alice's descent: Puts them both at risk but also provides the emotional support and eventual sacrifice needed to survive. Consequences: Alice discovers his notebook and suspects betrayal; they fight and separate; he ultimately saves her.
- Hiding his chronic illness and guilt: Maintains his façade of effortless brilliance but prevents Alice from understanding his vulnerabilities. Consequences: she misinterprets his motives and chooses the green apple.
- Sacrificing himself in the Escher trap: The pivotal decision. Peter uses the Hangman's Paradox to create an escape for one person and chooses Alice. The consequence is his temporary death, later reversed, but the act proves his love and dissolves all deception.
- Confessing his true plan: In the cave of Violence, he admits he intended to ask Alice to sacrifice him. This restores trust and deepens their connection, allowing Alice to later resurrect him.
Theme and Symbol Connections
Peter embodies several major themes in Katabasis. His hidden illness links to the sacrifice-and-redemption theme: he offers his own life to atone for his role in Grimes's death and to save the woman he loves. His chronic condition also connects to memory-and-identity: he hides the Beast because he fears it would redefine how others see him, just as Alice's perfect memory (from Grimes's tattoo) challenges her sense of self. His withdrawal after their project illustrates the theme of academic ambition and abuse: he prioritizes his career and self-protection over emotional connection, mirroring the toxic environment Grimes created.
Peter also reflects the nature of Hell: his own hell is partly self-inflicted through guilt and secrecy. The fact that Hell's landscape mirrors sinners' moral universes applies to him as well—his private shame over his illness and his complicity in Grimes's death haunt him as much as the external obstacles.
Five Book-Specific Questions and Answers
1. Why does Peter insist on joining Alice's descent to Hell in Chapter One?
Peter insists because he has been researching Hell independently and feels guilty over his role in Grimes's death—he missed lethal errors while proofreading a paper, causing an explosion that killed multiple people. He also loves Alice and wants to protect her, though he does not admit this openly.
2. What is the "Beast" Peter refers to, and why does he hide it?
The Beast is his Crohn's disease, a chronic inflammatory condition. He hides it out of shame and a lifelong determination to appear strong and independent. He fears that showing vulnerability would undermine his reputation as a prodigy and burden others.
3. At the Weaver Girl's test in Chapter Twelve, Alice chooses the green apple. Why does Peter choose red?
Peter chooses red ("together") because he genuinely trusts Alice and wants to continue their partnership. His choice reflects his hope that they can overcome their rivalry and work as a team, while Alice's green apple choice reveals her deep-seated fear that he will betray her, based on his earlier withdrawal and her misinterpretation of his notebook.
4. What does Peter confess in Chapter Twenty-One that changes Alice's understanding of him?
Peter confesses that he never planned to trade Alice's soul for Grimes's. Instead, he intended to ask her to sacrifice him because he blames himself for Grimes's death. This confession dissolves all deception between them and restores her trust.
5. How does Peter sacrifice himself in Chapter Twenty-Three, and what is the result?
Trapped in the Escher illusion of the Violence court, Peter uses the Hangman's Paradox to create an escape for one person only. He cuts his arm and chants, sending Alice out alone onto a barren plain. His sacrifice kills him temporarily, but Alice later resurrects him by destroying Grimes's shade in a magical exchange. The act proves his love and allows them to ascend from Hell together.
