Murder Your Employer Ending Explained – A Complete Spoiler Guide

Warning: This article contains major spoilers for the entire plot of Murder Your Employer: The McMasters Guide to Homicide, including the climax, character fates, and the ambiguous postscript. Read only after finishing the book.

The Climax: How Cliff Iverson Deletes Merrill Fiedler

The novel’s central deletion takes place in Chapters XLV through XLVII. After graduating from McMasters, Cliff Iverson executes a carefully layered plan against his former boss, Merrill Fiedler.

Cliff poses as a florist named Ludis Lanka to gain access to Fiedler’s office at Woltan Industries. He arrives with a bottle of Zwack Unicum liqueur obtained from Jack Horvath’s widow, Lilliana. Inside the office, Cliff pours two glasses from the same bottle, which he has laced with delphinine, a fast-acting poison. Unbeknownst to Fiedler, Cliff’s own coffee cup contains potassium permanganate (Condy’s crystals), which instantly neutralizes the delphinine.

During their confrontation, Cliff presents Fiedler with a “way out”: a document exonerating Lilliana Horvath. Fiedler signs it but also tries to poison Cliff a second time by adding what he believes is extra poison to Cliff’s glass—only that “poison” is actually the antidote from the stoneware bottle. By attempting to murder Cliff, Fiedler inadvertently drinks the newly poisoned liqueur. Cliff later explains: “If you’d done nothing with the supposed poison, then we’d both be dying… but I would have let you have the antidote.” Since Fiedler acted, Cliff pockets a backup vial of antidote and lets the delphinine kill his employer. The death is swift and painful.

Afterward, Cliff stages the scene as a suicide. He uses a pawnshop typewriter with deliberately nicked typebars to forge a two-page suicide note in which Fiedler confesses to creating a deadly flaw in the W-10 aircraft and to gambling debts. Cliff trims the pages, attaches Fiedler’s genuine signature to the second page (which originally exonerated Lilliana), and places the stapled note next to the typewriter. He also resets the typewriter ribbon to hide earlier typing. The final scene shows Cliff burning his own written confession and cleaning the glass, leaving Fiedler’s body to be discovered Monday morning. The police will rule it a suicide.

Major Character Outcomes

Character Fate
Cliff Iverson Graduates McMasters. His thesis is approved. By Chapter LII, he becomes a faculty member at the school, working as a science professor. He reveals his survival to Gemma Lindley and her mother when they arrive as new students.
Merrill Fiedler Dies from delphinine poisoning. His death is officially ruled suicide, with a planted note that exposes his corruption.
Jack Horvath The reader learns (via Cliff’s final letter to Dean Harrow) that Horvath was not murdered by Fiedler; he committed suicide in Ellwood Park, staging it to look like a murder so his insurance policy would pay out to his widow. Cliff helped him acquire the antique .22 pistol.
Lilliana Horvath Exonerated by the forged suicide note. She survives, believing Cliff avenged her husband.
Gemma Lindley Arrives at McMasters as a new student in Chapter LII, accompanied by her mother Isabel. She does not complete her thesis within the novel.
Dean Harbinger Harrow Alive in the postscript, but his final fate is ambiguous (see below).
Jud Helkampf No specific outcome in the provided evidence; he appears as a senior student who wins the poison-dinner exercise in Chapter XII.
Simeon Sampson Aids Cliff’s graduation by confirming his thesis viability at the end of Chapter XXV.
Doria Maye (Dulcie Mown) Her deletion thesis against Leon Kosta is described in Chapter XXV, but her final outcome is not covered in the ending chapters.

Resolved and Unresolved Threads

Resolved

  • Cliff’s revenge: He succeeds in making Fiedler’s death look like suicide while exposing the W-10’s fatal wing-flaw.
  • Jack Horvath’s death: Clarified as a deliberate suicide for insurance money, not murder.
  • Lilliana Horvath’s legal risk: Eliminated by the false confession.
  • Cliff’s survival at McMasters: He graduates and becomes a faculty member, establishing a new life.
  • Gemma’s arrival: She joins the school with her mother, ensuring the next generation of deletists.

Unresolved

  • Dean Harrow’s fate: The postscript cuts off mid-sentence as his honour guard arrives to take him to the kiln room to view his bust. It is heavily implied that the “meeting your maker” joke may be literal—his guards (Stedge, Tarcott, Daimler) might be executing him. The text never confirms his survival or death.
  • Gemma’s thesis: Who she plans to delete is not revealed.
  • The W-10 aircraft: While the suicide note confesses to the flaw, no explicit scene shows the plane grounded or fixed. The reader assumes the confession will trigger an investigation.
  • The board’s reaction: Erma Daimler initially opposed the publication of the guide but later relents, quoting Shakespeare. The broader institutional consequences remain off-page.

Theme Resolution

The novel’s central ethical question—“is this murder necessary?”—is answered ambiguously. Cliff’s deletion succeeds through manipulation of Fiedler’s own murderous intent. The book suggests that justified homicide requires the target to be a true villain who cannot be stopped legally. Fiedler, who caused deaths through design flaws and ruined lives, fits that category. Yet Cliff’s methods involve deception, forgery, and psychological entrapment, complicating any simple moral judgment. The theme of abuse of power and retribution is fully resolved: Fiedler’s arrogance (assuming he could outsmart Cliff) leads directly to his death. Meanwhile, institutional secrecy and loyalty are reinforced: McMasters protects its own by either graduating students or eliminating them. Cliff’s transition to faculty highlights how the school perpetuates its methods across generations.

The Postscript and Dean Harrow’s Ambiguous Fate

Chapter 55, the Postscript, is written from Dean Harrow’s perspective. He celebrates the guide’s publication despite board opposition, praises Erma Daimler for reversing her objections, and announces plans for future volumes. He then hears his honour guard arriving and says he will conclude after viewing his own bust being removed from the kiln. The text ends mid-sentence: “if I have accomplished nothing more than to have introduced you to the bas—” An editor’s note reads “[The text ends here. —Ed.]”

This abrupt cutoff is widely interpreted as either:

  • A playful meta-joke, with the dean’s death/hiatus interrupting the manuscript.
  • A literal indication that Dean Harrow was killed by his own honour guard (perhaps Erma Daimler orchestrated the “meeting your maker” ceremony as a retirement or termination).
  • A cliffhanger for the planned series, leaving his survival uncertain.

No sequel has been published as of 2025, so the ambiguity stands.

6 Reader Questions Answered

1. Did Cliff Iverson actually kill Merrill Fiedler?

Legally and narratively, yes. While Fiedler poisoned himself, Cliff engineered the circumstances knowing Fiedler would try to kill him. Cliff admits, “I am just as responsible for this deletion as any McMasters graduate had ever been.” The book treats it as a successful deletion.

2. What was Jack Horvath’s real cause of death?

Horvath committed suicide by gunshot in Ellwood Park. He intentionally made it look like murder so his life insurance policy would pay out to his wife. Cliff helped by buying the antique .22 pistol from a pawnshop. This twist is revealed in Cliff’s final letter to Dean Harrow (Chapter L).

3. Is Dean Harrow dead at the end of the book?

The text leaves his fate unknown. The postscript cuts off mid-sentence as he descends with his honour guard to view his bust. Given the school’s ruthless policy toward threats, it is possible he was killed to ensure the book’s publication wouldn’t expose McMasters. However, the tone is playful, and he may simply be interrupted.

4. Did Gemma Lindley succeed in her own deletion?

No information is provided. She appears only as a new student in Chapter LII, and her thesis target is never mentioned in the provided evidence. The novel ends before her story is resolved.

5. What happened to the W-10 aircraft’s dangerous design flaw?

The forged suicide note confesses that Fiedler created the flaw while trying to sell designs to a competitor. The note is left for police, implying an investigation will ground the plane. The novel does not depict the outcome, but the confession is intended to save lives.

6. Will there be a sequel?

Dean Harrow mentions future volumes covering mates, relatives, and “Murder Those Cruel to You in Adolescence.” The author Rupert Holmes has not announced a sequel. The ending is designed to allow further installments, but none have been released as of 2025.

Conclusion

Murder Your Employer delivers a technically clever climax that honors its McMasters teachings: make the target do the work, disguise the death as something else, and walk away clean. The ending provides closure for Cliff’s arc while leaving enough ambiguity—especially around Dean Harrow—to fuel speculation. It reinforces the book’s darkly comic thesis that some employers deserve deletion, provided the deed can be ethically and safely executed.
