I Found You Summary: The Deep Dive
SPOILERS WARNING: This section reveals the full plot, including the ending.
Alice Lake lives in Ridinghouse Bay, a small coastal town in East Yorkshire. She is a single mother of three, scraping by as an artist. One rainy night, she spots a man sitting alone on the beach. He has no memory of who he is or how he arrived.
Alice takes him home and calls him Frank. He is kind, gentle, and deeply confused. She tries to help him uncover his identity, posting his photo online and retracing his steps. Frank experiences fragments of memory—a carousel, a drowning, a girl’s face—but nothing clear.
Meanwhile, Lily Monrose lives in Surrey. She is Ukrainian, newly married to a man named Carl, and pregnant. Carl disappears three weeks after their wedding, failing to come home from work. Lily reports him missing.
The police deliver a shocking truth: Carl Monrose does not exist. His passport is fake. His identity is a complete fabrication. Lily is left alone in a foreign country, married to a ghost.
In another timeline, the novel flashes back to 1993. The Ross family—Tony, Pam, Gray, and Kirsty—arrive in Ridinghouse Bay for their annual summer holiday.
They meet Mark Tate, a charismatic nineteen-year-old who lives nearby. Mark becomes obsessed with fifteen-year-old Kirsty.
Mark invites Gray and Kirsty to a party at his house. The night turns violent when Mark tries to assault Kirsty. Gray intervenes, breaking his wrist in the struggle.
Mark drags Kirsty into the North Sea. Tony Ross suffers a fatal heart attack on the beach while trying to rescue them. Both Kirsty and Mark are presumed drowned.
Gray, traumatized, develops a fugue state and forgets the entire event. He spends the next twenty-two years living in Croydon, believing his sister died in an accidental drowning.
Then, twenty-two years later, Gray spots Mark in London. Mark is alive. He faked his death. All of Gray’s memories come flooding back.
Gray stalks Mark, kidnaps him, and imprisons him in an abandoned building site. He tries to strangle Mark, believes he has killed him, and flees back to Ridinghouse Bay. He collapses on the beach—the same beach where Alice finds him.
As Alice helps Frank recover, Lily’s investigation brings her to Ridinghouse Bay. She meets Alice and Frank in a local café. Lily shows them a photo of her missing husband. Frank instantly recognizes the face. He is Graham Ross. The man he “killed” is Lily’s husband.
The group tracks down Mark’s aunt, Kitty Tate. Kitty reveals the horrifying truth: she found Mark and a barely alive Kirsty on the rocks after the 1993 incident. Mark forced Kitty at knifepoint to let Kirsty die without medical help. He then buried the body in Kitty’s garden.
Lily calls the police. Mark, however, was not killed by Gray—he escaped and fled to the Scottish Highlands. He takes a landlady and her daughter hostage before authorities finally apprehend him.
Kirsty’s remains are recovered and given a proper burial in Croydon. Mark faces multiple charges, including abduction and unlawful burial.
Lily moves to Putney to start a new life. Alice and Graham reconnect at the funeral, acknowledging their bond and planning a future together after Graham completes his psychiatric treatment.
