The novel’s central symbol, the lake, represents the dangerous illusion of perfection that characterizes the town of Summit Lake and some of its inhabitants. On its surface, the lake is picturesque and serene, a feature that draws tourists and weekenders to what seems like an idyllic mountain retreat. This placid facade, however, conceals the murky depths that lie beneath, mirroring how the town’s pristine reputation masks the dark secrets and corruption that led to Becca’s violent murder.
Kelsey’s first impression from the bluff captures this dichotomy perfectly: “Somewhere in this quaint tourist town, a girl had been murdered. It seemed too nice a place for such a thing to happen” (21). This observation establishes the novel’s core tension between appearance and reality, suggesting that the most beautiful surfaces can hide the most brutal truths. The lake doesn’t change, but its meaning deepens as the investigation uncovers the secrets it metaphorically holds. It’s a constant, looming reminder that suppressing truth doesn’t eliminate it but merely submerges it, allowing it to fester in the depths. The stilt houses, perched precariously over the water, extend this symbolism, representing the fragile, carefully constructed lives of families like the Eckersleys, built just above the hidden things beneath the surface that may threaten to erode their foundations.
The journal, which Becca leaves in the coffeehouse and Millie later tucks into her recipe book at home, symbolizes unvoiced truth and the devastating consequences of secrecy. As a physical object, it embodies the hidden inner life Becca concealed behind her “squeaky clean” public persona, making its recovery the narrative key to unraveling the mystery of her murder. The journal thematically connects to The Destructive Power of Secrets and The Dangerous Illusion of Perfection, as its pages contain the truths (her secret marriage and pregnancy) that shattered her perfect image and ultimately led to her death.
The search for the journal propels Kelsey’s investigation, transforming it from a mere object into the central focus of her quest for clarity. Its confirmed existence heightens the narrative tension, especially since it’s missing from the official evidence list. Millie Mays’s recollection of Becca’s final hours underscores its significance: “When Livvy finally went over to talk to her […] she was scribbling away in her journal. Livvy said she was gushing” (80). This detail places the journal at the heart of Becca’s last confession, making it a sacred text of her final thoughts and feelings. Its eventual discovery isn’t just a plot resolution but also a symbolic act of giving voice to the dead, allowing the truth to surface and expose the destructive nature of the secrets it held.
The motif of running charts Kelsey’s psychological journey and embodies the novel’s theme of Investigation as a Path Toward Healing. For Kelsey, running is inextricably linked to her own assault, transforming a source of freedom and reflection into a site of trauma. Her return to this activity in Summit Lake isn’t merely for exercise but is a conscious and arduous effort to reclaim her agency and confront her deep-seated fear. The narrative highlights her internal battle before her first jog into the forest: “Nope. Won’t let you do it to yourself, Castle. With a deep breath, she took off into the forest in a slow jog” (31). This moment of determination signals the beginning of her healing process, which unfolds in parallel with her investigation into Becca’s murder. Each run through the woods of Summit Lake is an act of defiance against her trauma, allowing her to process her own pain by seeking justice for Becca.
The motif culminates in the novel’s final scene, when Kelsey runs her old path in Miami, passing “The Spot” where she was attacked. This final run isn’t one of fear but of triumph, symbolizing that by confronting the darkness in Becca’s case, she has successfully navigated her own, emerging stronger and no longer controlled by her past.
