I Am Watching You Summary (Spoilers Ahead)
Spoiler warning: this section covers the complete plot, including the ending.
In July 2015, Ella Longfield travels to London for a floristry conference. In her carriage are two sixteen-year-old friends from Cornwall, Anna Ballard and Sarah Headley, on their first solo trip to see Les Misérables. Two men, Karl Preston and Antony, join them and mention they have just left Exeter Prison.
The men invite the girls to a Vauxhall nightclub. Ella walks to the buffet car intending to warn them, feels humiliated by their reaction, and returns to a different seat.
The next morning she sees Anna’s face on a missing person alert. Ella contacts the police, but her identity leaks to the press, and she and her husband Tony face harassment that forces her to close her flower shop.
A year later, a Crimecatchers reconstruction brings the case back into public view. Ella begins receiving black postcards with cut-out letters, including the line “I AM WATCHING YOU,” and hires private investigator Matthew Hill.
Meanwhile, Sarah is hiding the truth. She had argued with Anna at the club and told her to get back to the hotel alone, then lied to police about it. Overcome by guilt, Sarah takes an overdose, survives, and leaves home to find her estranged sister Lily.
Anna’s father Henry Ballard is also hiding something. He claimed he had slept in his car on the night of the disappearance, but he was actually with a woman named April. When police learn his car was spotted near a station with trains to London, he becomes a suspect and locks himself in his barn with a shotgun.
Sarah then tells Lily that their father Bob abused them as children, and reports him, believing he may have taken Anna. Police clear Bob using hotel CCTV and mobile data.
In Spain, a viewer recognizes Karl Preston, and armed police surround his apartment. He takes a blonde woman hostage, causing worldwide speculation that Anna has been found alive. Matthew studies the photographs, notices the hostage’s body shape does not match Anna’s, and alerts DS Melanie Sanders. The woman is Karl’s girlfriend. Karl and Antony are arrested and cleared.
With every suspect eliminated, Barbara Ballard asks Matthew to review the case. Matthew brings Ella to the Ballard farmhouse, where she spots a Ten Tors photograph on the piano. In it she recognizes Tim Blackhouse, a childhood friend of Anna and her sister Jenny.
Ella realizes she saw Tim on the London train that day, though he had told everyone he was hiking in Scotland. In truth, he had signed into the trek to create an alibi and travelled south in disguise.
Tim had fixated on Anna for years, photographing her secretly and keeping diaries about watching her. As his secret begins to unravel, he goes to Ella’s shop in Trundale, where her son Luke is working alone.
Tim confronts Luke with the photograph and accuses him of being a rival for Anna. He locks the door and attacks Luke with a knife. Luke fights back, throws hot coffee, and stabs Tim with Ella’s red-handled pruning secateurs.
Police search a secret London flat owned by Tim and find Anna Ballard’s body stored in a freezer, along with boxes of stalking diaries and photographs. Anna had run into Tim outside the club, accepted his offer to wait for a taxi at his flat, discovered the photos, and been strangled with a belt when she tried to leave.
Luke survives with serious injuries, and Tim is left in a coma. Barbara later tells Ella that the first two hate postcards came from Anna’s sister Jenny, and that Jenny had confided in Tim, prompting him to send the rest.
Barbara asks Ella to make a meadow-style arrangement of wild flowers, hostas, primroses, and bluebells for Anna’s coffin instead of a traditional wreath.
In I Am Watching You, Teresa Driscoll closes with Ella promising to create it.
