Answer Key

Plot and Sequence

Question 1: B — The narrator is a flower delivery driver bringing a bouquet addressed to Nina Swann & Family, observing a wake through the window (Chapter 1). The condolence card arrives later from Nick (Chapter 3), the Zippo comes by post (Chapter 5), and the soaps appear as a Christmas gift much later.

Question 2: C — Paddy is pushed under a train by Joe Kritner two weeks before the novel opens (Chapter 2). Drowning is how the antagonist appears to die, and suicide is Luke Berner's fate.

Question 3: C — Nick sends a copper Zippo lighter with a note claiming it belonged to Paddy, which Jane Trevally later disproves—Paddy never owned a lighter (Chapters 5 and 24). The gold ring is found, not sent; the photo album belongs to the family; the medical bag is the antagonist's own.

Question 4: C — Ash discovers a large gold ring in her mother's bedroom rug and pockets it (Chapter 14). Nina speculates it is a memento of Nick's supposedly dead fiancée. The hidden phone is found by Martha, the dog tracker is Martha's device, and the ladybird charm and pacifier clip are found in Nick's coat pocket by Ash.

Question 5: Model answer — Ash shows a photo of Nick to the shop assistant, who identifies him as Alistair, Martha's husband. Ash learns he has been away since before Christmas, supposedly caring for his mother with Alzheimer's. This confirms Nick's double life and that he is a married father living in Kent (Chapter 60).

Question 6: C — At the pavilion, Emma calls him a loser, he punches her, his sons pin him down demanding to know what happened to their mother, and he breaks free, runs across the beach, and walks into the icy sea (Chapters 77–78). No body is recovered.

Question 7: B — Joe Kritner recoils at the photo of Nick Radcliffe and confirms Nick is the "Silver Man" who approached him outside Leicester Square station with a fabricated story about a terrorist bomb (Chapter 68). CCTV footage is sought to corroborate the testimony.

Question 8: Model answer — His unnamed first wife (the only one who knew his real name, Simon Smith) reveals she was the woman captured on CCTV wearing Tara's clothes as a decoy, and she admitted to helping Simon dismember Tara's body and dispose of it around the M25. She arranged for a plainclothes detective to wait in her Algarve cottage and stepped aside as police arrested him, accepting she would go to prison too (Epilogue).

Character Motivation

Question 9: B — Ash consistently voices concern that Nick is after her mother's money, noting his unglamorous rented flat in Tooting and his eagerness to invest Nina's assets in the Bangate Cove scheme (Chapters 11, 20, and 29). Her distrust deepens with every lie she uncovers.

Question 10: C — In Chapter 28, Damian tells Amanda he lost money in a Ponzi scheme and owed a violent loan shark, so he faked his drowning. Options A and D are lies he tells to other victims; murder comes later.

Question 11: Model answer — Martha clings to the belief that she has the "best version" of him, rationalizing his behaviour as ADHD and emotional baggage. She recalls the good moments—his tenderness with Jonah about gender identity, his help at the flower shop, his charm—and fears dismantling the family unit she has constructed. Her self-deception only breaks when she sees the evidence of the champagne receipt from the night Nala was hospitalised (Chapters 22, 33, 47, and 50).

Question 12: B — In Chapter 51, Alistair recalls Paddy humiliating him in an alleyway, and he seethes with envy over Paddy's restaurant success and family. In Chapter 54, he stalks Ash on social media and fantasises about ruining Paddy. He never had a business deal with Paddy, Nina did not hire him, and his goal is destruction, not genuine investment.

Question 13: Model answer — Emma Greenlaw contacts Ash because her mother, Tara, disappeared after confronting Nick (then calling himself Jonathan) at a Tooting flat. Emma warns Ash that Nick is a psychopath who kills when his cover is blown, and she urges Ash not to spook him but to gather evidence carefully before acting (Chapters 62).

Theme and Symbolism

Question 14: B — The pink box first appears with the Zippo, then as a Christmas soap gift to Ash, and Marcelline reveals her ex-boyfriend Jason gave her an identical one. Tracing the soaps leads Ash to Martha's shop. The box embodies Nick's shallow, recycled romantic gestures and becomes a crucial clue (Chapters 11, 45, 52, and 60).

Question 15: B — Each ring exposure coincides with revelations about the antagonist's compartmentalised life. Alistair claims he lost his ring at a gym that does not exist; Ash's found ring suggests another hidden relationship; the stolen sapphire ring funds his escape. Together they symbolise the fraudulent performance of commitment (Chapters 15, 22, 23, and 31).

Question 16: Model answer — The sea represents escape, erasure, and the final dissolution of identity. Nick pitches coastal schemes at Bangate Cove, stalks women near seaside towns, and ultimately walks into the water, leaving no body behind—mirroring how his identities vanish without a trace. The sea swallows evidence as thoroughly as he covers his tracks.

Question 17: B — Ash explicitly notes the frozen food as a marker of time standing still since Paddy's death: one year later, the freezer still holds items from her father's lifetime. It symbolises Ash's stagnation and her resistance to moving forward (Chapter 7).

Synthesis

Question 18: Model answer — Both women rationalise red flags: Ash initially fears Nick is a gold-digger but cannot convince Nina; Martha dismisses Alistair's absences as ADHD and work crises. For Ash, the breakthrough comes when she visits Enderford and learns Nick is Alistair, a married father. For Martha, the shattering moment is finding the champagne receipt from Paddy's restaurant dated the night Nala was hospitalised—proving Alistair lied about his whereabouts during a family crisis. Both must overcome the powerful desire to preserve the relationships they have built around the deceiver.

Question 19: A — Across Laura, Tara, Martha, Nina, Jessie, and numerous other victims, the antagonist follows the identical template: intense charm and love-bombing, escalating financial exploitation, elaborate lies about sick mothers and dead fiancées, and abrupt vanishing—or violence—when exposure threatens. The pattern is explicitly documented in Emma Greenlaw's timeline (Chapters 62 and 76).

Question 20: B — The Facebook group "DON'T LET HIM IN" organises the victims for the final confrontation (Chapter 76). Beyond the literal warning, the title encapsulates the novel's central caution: predators like Simon Smith gain access by exploiting trust, loneliness, and the desire for love. The phrase applies to every woman he targeted.
