The Head Collector Book Club Questions
by Mark Griffin
These questions assume everyone has finished the book and contain spoilers, including the ending.
At first glance this novel is a tense procedural, but the real discussion fuel comes from its tangled questions about grief, perception, and who gets trusted. The characters carry private losses into an investigation full of bad assumptions, slippery suspects, and psychological games, so readers will likely disagree about motives, evidence, and what counts as recovery.
Use these questions as a loose menu rather than a test. Pick a few that spark strong reactions, ask everyone to point to specific scenes, and let the conversation move between character choices, investigation ethics, and mental health. Spoilers appear below, so finish the book first.
Grief, Family, and First Impressions
- 1.Early on, Mary Jane Rosette dreams of chasing Benji the parrot before waking restrained in the basement and speaking to Roger; how does that disorientation affect the way you read the later claim that her death was a self-inflicted guillotine suicide?
- 2.At Mary Jane's house, Oswald seizes on the open basement door, her lack of make-up, the unburned candle, and the cortisol test to argue murder; did his reasoning persuade you, and why or why not?
- 3.Detective Anderson keeps her dead husband's clothes, watch, sleeping pills, and cufflinks and says 'Hello, beautiful' to his photo, while Oswald wears hair ties for Leo, Robert, and Hannah; how does the novel use private grief to shape their investigation of Mary Jane's death?
- 4.Roger Rosette tells Anderson and Oswald he still thought of Mary Jane as his wife, and Clementine curls on the sofa during the interview after finding her mother's body; how did their grief affect your suspicion of Roger or your sympathy for Clementine?
Suspects, Surveillance, and Police Assumptions
- 5.Errol Jameson Green invents Lucy Wentworth, harasses Mary Jane, and keeps a wall of photographs of women, yet Oswald dismisses him as too dumb for the murder; did you see Errol as a credible suspect, and what does his treatment reveal about how the investigation handles dangerous but non-murderous men?
- 6.Oswald and Anderson find bleach-soaked clothing, empty tins, urine and faecal matter in a cooler, and endoscopic cameras in Mary Jane's attic; how does the killer's long stay in the house change the way you understood the murder and the surveillance of Clementine?
- 7.The unlogged can opener in the doorbell footage leads Oswald to argue that the killer walked out disguised as a CSI; how did this 'hiding in plain sight' turn affect your view of the police investigation and Anderson's assumptions?
- 8.Harper identifies the basement angel as St Dymphna, the patron saint of mental illness and suicides, and the second victim has St D markings cut into his eyelids; what does the novel suggest by making a martyred saint central to the killer's ritual?
Manipulation, Trust, and Recovery
- 9.Martin Brown chairs the Hope Gateway meeting, offers to sponsor Mary Jane, and later confesses to killing Laura Brown, Mary Jane, Karl Lobanov, and Jason Warden; how does his role as a trusted recovery-room figure make his psychopathy more disturbing?
- 10.Martin repeatedly gaslights Oswald—denying the 'finally get together' remark and claiming he told Oswald about Karl when Oswald was at USM—before Oswald realizes his fingerprint was used on Karl's fake confession; how did this manipulation affect your trust in Oswald's judgment?
- 11.DA Charles Reese calls the case airtight and fast-tracks the partial fingerprint on Karl's note, while Oswald warns it is secondary transfer and calls 911 to complain about Reese; did you agree with Oswald's decision to file that complaint, even though he knew it was self-sabotaging?
- 12.Oswald tests Martin with a yawn and later Martin describes making people think he is good as the 'gold standard of psychopathy'; how convincing did you find the yawn test as a clue, and what does it reveal about Oswald's methods?
- 13.Oswald's visits to Nora and Anthony Bennet in separate prison wings reveal a family history of attempted mutual murder, while his mother tells him not to put all psychopaths in the same category; how does Oswald's family background shape his ability to recognize Martin Brown?
Confrontation and Aftermath
- 14.In the Hope Gateway Church basement, Martin shows Harper on a monitor and forces Oswald to play a suicide game; Oswald shoots out the camera, fakes his death, and eventually shoots Martin; did you agree with his choices, and what did you make of Martin's claim that 'Your life is in my hands. I decide'?
- 15.The novel ends with Oswald at the bathroom mirror saying 'Good morning, Oswald Bennet,' breaking down, and then saying 'One day at a time,' while a speaker tells Maisie that 'Life is everything in between'; did that ending feel like closure for Oswald's story, and how did it connect to the book's treatment of depression and recovery?
