Verity recap

Writer Lowen Ashleigh is hired by Jeremy Crawford to complete the bestselling series of his wife, Verity, who appears profoundly disabled after an accident. Staying in the Crawfords' home, Lowen discovers an unpublished autobiographical manuscript in which Verity describes an obsessive marriage, resentment of her twin daughters, and responsibility for Harper's drowning. Lowen also suspects that Verity is secretly alert and moving. As Lowen and Jeremy begin an affair, her fear of Verity grows. Jeremy reads the manuscript, confronts Verity, and joins Lowen in killing her while disguising the death. Later Lowen finds a hidden letter claiming the manuscript was merely a sinister writing exercise and that Verity feigned incapacity because Jeremy had attacked her after mistaking fiction for confession. Unable to know whether the manuscript or letter is true, Lowen destroys the letter. Pregnant and building a life with Jeremy, she keeps both their crime and the uncertainty to herself.

Lowen Ashleigh witnesses a pedestrian's violent death on a Manhattan street shortly before a publishing appointment. A stranger named Jeremy Crawford helps her clean the blood from her clothes, and she soon learns that he is attending the same meeting. Jeremy's wife, bestselling author Verity Crawford, is no longer able to write after a serious accident. Her publisher wants Lowen to finish the remaining books in Verity's series. Lowen is uneasy about taking over another writer's work, but the contract would rescue her from mounting financial trouble after her mother's death. Jeremy invites her to the family home in Vermont to search Verity's office for plans and background material. Lowen accepts the job and prepares for a short stay with the Crawfords.

At the Crawford house, Lowen meets young Crew and sees Verity, who appears unable to communicate or move intentionally and receives constant care. The household is burdened by the earlier deaths of Verity and Jeremy's twin daughters, Chastin and Harper. While sorting the chaotic office, Lowen finds a manuscript apparently written by Verity as a candid account of her life. Instead of useful notes about the published series, it describes Verity's intense fixation on Jeremy, the beginning of their marriage, and her troubled response to pregnancy and motherhood. Lowen hides the document and reads it privately. She is disturbed by its cold account of the family and increasingly drawn to Jeremy, whose grief and kindness make the intimacy of the manuscript feel dangerously immediate.

Lowen continues reading Verity's manuscript while working on the contracted novel. Its account portrays Verity as jealous of the attention Jeremy gave their children and especially hostile toward Harper. In the house, Lowen notices fleeting signs that Verity may be more aware than her condition suggests, but each incident is difficult to prove and Jeremy attributes some of Lowen's anxiety to exhaustion. Crew injures himself with a knife and gives an unsettling explanation involving his mother. Lowen and Jeremy become emotionally closer as he speaks about the losses that shattered the family. Lowen does not show him the manuscript, fearing both its effect on him and the possibility that revealing she has read it will end her place in the house.

The private account describes the deaths of both twins and presents the second death as deliberate: Verity claims she tipped Harper from a canoe and allowed her to drown. Lowen now views Verity as a threat to Crew and watches her constantly. At the same time, Lowen and Jeremy's attraction becomes a sexual relationship, binding Lowen more closely to the family and giving her another reason to want the manuscript's version of Verity exposed. Verity's seemingly impossible movements continue, including moments when Lowen believes she sees awareness and hostility in her face. Jeremy remains reluctant to believe that his wife could be pretending, and Lowen struggles to produce evidence that cannot be explained away.

Convinced that Verity can move, Lowen sets up a way to test her and obtains stronger proof that the invalid performance is false. The danger feels immediate when Crew repeats things that suggest private communication with his mother. Lowen confronts Verity and makes clear that she no longer accepts the deception. Her relationship with Jeremy is also no longer temporary: they imagine a future together even though Verity remains in the house. Lowen finally decides that withholding the manuscript is more dangerous than revealing it. She leaves it where Jeremy will find the passages concerning Harper, knowing that his understanding of his wife and his daughter's death will be transformed if he believes what Verity wrote.

Jeremy reads the manuscript and confronts Verity. She abandons the appearance of total incapacity, but Jeremy accepts the document as a confession that she murdered Harper. Lowen helps him kill Verity and stage the death so that suspicion will not fall on them. They later begin a new life together, and Lowen becomes pregnant. While clearing the old house, Lowen discovers a hidden letter from Verity to Jeremy. It offers a radically different explanation: the manuscript was an exercise in writing from the mind of an evil character, and Verity had pretended to be incapacitated because Jeremy had already found it, believed it, and attacked her. The letter explains many of the same events without resolving whether Verity is honest. Lowen destroys it rather than expose Jeremy or endanger her new family. The story closes with Verity dead, Lowen and Jeremy joined by love and a concealed killing, and the truth of the two documents unknowable.

Lowen finally lets Jeremy read the private manuscript, which appears to confess Verity's hostility toward Harper and describes Verity deliberately causing the child's drowning. Jeremy confronts his wife, and when Verity reveals that she can move and tries to defend herself, he and Lowen kill her and arrange the scene to resemble a natural consequence of her condition. Months later, Lowen is pregnant with Jeremy's child and the couple are clearing the Vermont house. Lowen finds a hidden letter addressed to Jeremy in which Verity claims the manuscript was only a writing exercise used to explore a villainous viewpoint. The letter says the frightening behavior Lowen witnessed came from Verity's attempt to protect herself after Jeremy found and believed the manuscript. Lowen cannot determine which document tells the truth. Recognizing that Jeremy could turn on her as he did on Verity, she destroys the letter and keeps its existence secret, preserving their shared version of events while accepting permanent uncertainty about the woman they killed.
