Plot Summary: What Happens in Something in the Water
Erin Roberts thought she had the perfect life with her husband Mark, but their honeymoon discovery changes everything in ways they never expected.
The Central Premise
Erin and Mark Roberts plan their dream honeymoon in Bora Bora after their wedding. They want to relax and enjoy their new marriage in paradise. But their underwater adventure leads to a discovery that will haunt them forever.
While diving, they find a sunken plane with a mysterious duffel bag inside. The bag contains a large amount of cash and important documents. These items belong to dangerous people who will stop at nothing to get them back.
The couple faces an impossible choice that will test their marriage and morals. They can report the find to authorities or keep the money for themselves.
Key Plot Points
Mark recently lost his job at the bank, leaving the couple facing serious money problems. The stress of unemployment weighs heavily on both of them. The discovery seems like the perfect solution to all their financial troubles.
The beautiful setting of Bora Bora contrasts sharply with the dark events that follow. What should be a romantic getaway becomes a nightmare of fear and violence. The couple must cover up their actions while staying one step ahead of danger.
Mark’s behavior becomes more controlling and suspicious as the story progresses. He makes decisions without telling Erin and puts them both at greater risk. His final betrayal reveals the truth about their marriage and his real feelings.
Thematic Elements And Literary Devices
Steadman weaves together multiple themes that examine human nature and the choices people make when faced with temptation and desperation.
Major Themes in Something in the Water
The book examines how ordinary people react when faced with extraordinary moral dilemmas. Steadman shows that anyone can become capable of terrible things under the right circumstances.
Money serves as both salvation and corruption throughout the narrative structure. The characters believe that wealth will solve all their problems, but learn otherwise.
Trust forms the foundation of all relationships in the store, but proves to be fragile. Erin and Mark’s marriage cannot survive the secrets and lies they tell each other.
Greed and Moral Corruption
The temptation of easy money proves too strong for both Erin and Mark to resist. They convince themselves that keeping the money is justified because they need it desperately.
Their criminal behavior escalates throughout the story as they try to cover their tracks. Each new lie requires more lies to maintain, creating a web of deception.
Both characters lose their moral compass as they prioritize money over everything else. They stop caring about right and wrong and focus only on survival.
Trust and Betrayal in Marriage
The relationship between Erin and Mark appears strong at the beginning of the story. They seem to communicate well and make decisions together as a team. But the pressure of their situation reveals cracks in their foundation that were always there.
Secrets and lies gradually replace honest communication between the couple throughout the book. Mark begins making important decisions without consulting Erin about the consequences.
The story raises questions about whether Mark ever truly loved Erin or if he was manipulating her. His willingness to betray her suggests that his feelings were never genuine.
Consequences of Choices
The couple’s initial decision to keep the money creates a butterfly effect that spirals out of control. Each choice they make leads to more difficult decisions and worse consequences. The story shows how one bad decision can destroy an entire life.
Several moments in the story represent points of no return for both characters. They have opportunities to stop and change course, but choose to continue down the wrong path.
The ending raises questions about justice versus survival in impossible situations. Erin must choose between doing what is legally right and protecting herself and her unborn child.
Writing Style and Narrative Structure
Catherine Steadman’s writing is crisp, engaging, and easy to get lost in. She balances tension with character development:
Non-linear Storytelling
The book opens with Erin digging a grave, immediately creating questions that drive the entire narrative. This technique hooks readers and makes them want to understand how events led to this moment.
Steadman uses flashbacks to slowly reveal the events that led to the opening scene. This structure allows her to control the pace and build suspense effectively throughout the book.
The non-linear structure keeps readers engaged and guessing throughout the entire story. Each chapter reveals new information that changes how readers view previous events.
First-Person Perspective
Erin serves as an unreliable narrator whose version of events cannot always be trusted. Her perspective colors every event and interaction in ways that may not be accurate. Readers must constantly question.
The first-person narration creates intimacy between Erin and readers that makes her choices more impactful. Readers feel connected to her decisions and find themselves questioning what they would do.
The “what would you do?” element engages readers on a personal level throughout the story. Steadman forces readers to examine their own moral boundaries and limits through Erin’s choices.
