Into the Water

by Paula Hawkins

Following the unexplained death of her sister, Nel, in a pool at the foot of a cliff, Jules Abbott returns to Beckford, a fictional town in Northumberland, to care for her niece, Lena. The novel is told in a mixture of first-person and third-person narrative.

Jules had been estranged from her sister Nel due to an incidence from their childhood. Nel assumed that Jules had seduced her boyfriend Robbie even though he was sexually abusing Jules. Lena is furious at Jules for not speaking to her mom. Lena believes that her mom jumped into the 'Drowning Pool', a place where multiple women throughout the town's history have died. Lena blamed her friend Katie's death on her mother's obsession with the pool. Jules does not believe that her sister committed suicide. She heard fear in Nel's last voicemail, imploring Jules to meet her. Jules informed Detective Sean Townsend about this. Detective Sergeant Erin Morgan sensed Sean's distress in the case and found out that his mother also committed suicide in the Drowning Pool.

Helen Townsend stays at her father-in-law Patrick's cottage as her husband betrayed her. Louise, Katie's mother, was relieved that Nel died as she holds her responsible for inspiring girls to become curious about the Drowning Pool. Her son Josh, however, is terrified that his mom was not at the house when Nel died.

Jules searches for her mother's bracelet which Nel wore all the time and is shocked to find that it is missing. Louise finds diet pills prescribed to Nel among Katie's belongings and tells Sean that Nel's murder should be made public. But it turns out that Katie asked Lena to buy her the pills.

Mark Henderson, Lena's teacher, finds Nel's bracelet in Helen's drawer while searching her room. Josh and Lena breaks his windows as revenge for Katie's death. Josh tells Sean that Mark seduced Katie, and Lena reveals that Katie sacrificed herself to protect Mark from being arrested for statutory rape. Louise confronts Lena for keeping the information from her, and Lena tells her she threatened Katie to end her relationship with Mark. After Louise leaves, she tells Jules that it was Nel who made the threat.

Erin comes to know that Nel and Sean had a relationship. She asks Sean about it and he barks at her to check his records. She meets Nickie, a con artist who tells her that she must look upon Lauren (Patrick's dead wife) and not Helen.

Lena waits for Mark at his home and tries to kill him but ends up injured. He ties her up and tries to escape with her in the car. He confronts her at his ex's cottage and tells Lena that he loved Katie and did not kill Nel. They fight, and Lena likely kills Mark. Lena tells Jules that Nel was murdered, having learned from Mark that Helen Townsend had a bracelet in her office that was missing from Nel’s body after her death. Jules goes to the Townsend house and accuses Helen of murdering Nel. Patrick (Sean's father) then confesses to killing Nel and to killing his own wife, Lauren, years ago.

In the months after Patrick’s confession, each of the characters leaves Beckford. Jules and Lena go to London and have a much stronger relationship than they did at the beginning. Patrick is in jail. Helen and Sean leave together, but Sean disappears one day and Helen does not look for him. Sean, in an undisclosed location, tries to come to terms with himself and admits that it was he who killed Nel.
