Plot Summary: What Actually Happens
The novel weaves together three storylines centered on one dangerous man.
Nina Swann is a widowed single mother rebuilding her life when she meets the charming Nick Radcliffe on a dating app. He seems attentive, warm, and exactly what she needs. Her daughter Ash is not convinced.
Meanwhile, Martha, a florist in a neighboring town, is married to Alistair, a man who vanishes for days at a time without explanation. She accepts his absences, until cracks appear in his carefully maintained life.
As Ash grows more suspicious of Nick, she begins digging into his past. The three women's stories collide when Nick's true identity unravels, exposing his con-man history and the aliases he has left behind across other women's lives.

Key Characters at a Glance
The novel's tension comes from how each character relates to the same man under different names. Nick Radcliffe is also known as Alistair "Al" in Martha's storyline and Sandy in his past.
| Character | Role | Relationship to Nick | Key Trait |
|---|---|---|---|
| Nina Swann | Protagonist | Girlfriend via dating app | Grieving, hopeful |
| Ash | Nina's daughter | Stepmother-figure skeptic | Observant, persistent |
| Martha | Florist | Wife of "Alistair" | Patient, loyal |
| Nick Radcliffe | Antagonist | Also Alistair/Sandy | Charming con man |
Jewell's multi-perspective structure means readers gradually assemble Nick's real identity from fragments. Each woman holds a piece of the puzzle the others lack.
Themes: Why the Story Resonates
The novel's power lies in its themes, which elevate it beyond a standard missing-husband thriller.
- Deception: Nick's entire persona is a constructed performance, maintained across multiple identities.
- Trust: Each woman must decide how much disbelief she is willing to absorb to preserve her relationship.
- Manipulation: Nick exploits vulnerability, particularly grief and loneliness.
- Identity: Aliases and invented histories blur the question of who Nick actually is.
- Intimate partner danger: The threat comes from inside the home, not outside it.
The Charm
Nick presents an idealized version of himself, tailored to each woman's emotional needs.
