Prologue – Summary & Analysis: This is Why We Lied

⚠️ Spoiler Warning: This guide contains detailed spoilers for the entire novel. Proceed only if you've finished reading or are comfortable knowing the plot.

Summary

Will Trent and Sara Linton are on their honeymoon at the McAlpine Family Lodge. After a tense dinner involving Mercy McAlpine and her family, the couple steals away to a secluded lake. Sara swims naked; Will joins her. They share an intimate moment, but their happiness is shattered by a blood‑curdling scream.

Will’s law‑enforcement instincts kick in. He runs toward the sound, while Sara follows more slowly. The scream comes again—a woman pleading for help. Will races through the woods, finds a cabin on fire, and searches inside, but the building is collapsing. He escapes just before the roof falls.

Emerging from the smoke, he spots a body half‑in, half‑out of the water. It is Mercy McAlpine. She has been repeatedly stabbed. Will checks for a pulse and finds she is still alive. Mercy, barely conscious, gasps out last words for her son Jon: he must get away, and Will must forgive him. Will promises to deliver the message. Mercy dies.

Sara arrives and stops Will from performing chest compressions—his hand has been impaled on the broken knife handle still embedded in Mercy’s chest. The Prologue ends with Will reeling from physical and emotional wounds.

Character Development

Will Trent: His vulnerability and tenderness with Sara contrast with his relentless determination when danger arises. The scene reinforces his trauma‑informed perspective (e.g., comparing Mercy’s skin to his mother’s autopsy photo) and his deep need to protect the vulnerable.
Sara Linton: While less active here, her calm professionalism as a doctor and her emotional support of Will are evident. She trusts Will’s instincts and later intervenes medically.
Mercy McAlpine: Though she appears only briefly alive, her fierce maternal love and her tragic end are central. Her final words prioritize her son’s safety over her own life.
Jon (mentioned): Mentioned only through Mercy’s dying plea, he becomes a symbol of the collateral damage of violence.

Themes, Symbols, or Motifs

Beginnings and Endings: The honeymoon—a symbol of new life—is violently interrupted by death. The idyllic lake and stars are juxtaposed with blood and fire.
Domestic Violence / Family Secrets: Sara’s earlier line, “Places like this, you scratch a little bit under the surface and all sorts of bad things come out,” foreshadows the hidden toxicity of the McAlpine family.
Sacrifice and Duty: Will’s immediate decision to run toward danger mirrors his lifelong pattern of putting others before himself. Mercy’s final concern is for Jon, not herself.
The Fragility of Life: Witnessing Mercy’s sudden death reinforces the ephemeral nature of happiness; Will’s own injury underscores the personal cost of justice.

Why This Chapter Matters

The Prologue establishes the central murder that will drive the narrative. It introduces Will and Sara in a moment of rare personal happiness, making the violent intrusion even more jarring. Key threads are set: the mystery of who killed Mercy, the role of her family, and Will’s emotional involvement with Jon’s fate. The chapter also plants the symbolic “Jackal” figure (mentioned by Will), hinting at a past that may resurface.

Study Questions and Answers

1. What does the lake scene reveal about Will and Sara’s relationship?
It shows their deep intimacy and trust. Will feels a happiness he has never known, and Sara openly expresses her desire for him. This peaceful moment makes the subsequent violence more shocking and underscores what Mercy’s death steals from her own family.

2. Why does Sara stop Will from performing chest compressions?
She sees that the broken knife handle is still buried in Mercy’s chest. Pressing down would push the blade deeper, severing nerves and possibly causing Will’s hand irreparable damage. Her medical training overrides instinct.

3. What is a possible symbolic meaning of the burning cabin?
The cabin, which is under renovation and partially boarded‑up, can represent the faulty, hidden structures of the McAlpine family. Fire consumes it just as violent secrets consume Mercy. Will’s near‑entrapment foreshadows the personal danger he will face in unraveling the truth.
