Grist Mill Road is the second novel by English author Christopher J. Yates published in 2018 by Picador.
In 1982, three teenagers are involved in a crime in a forest 90 miles north of New York City. Hannah (the rich daughter of a cement dynast) is tied to a tree, Matthew shoots her with a Red Ryder BB Gun and she loses an eye. Patrick (Patch) is secretly watching, counting the shots over 40 times, and he thinks that Matthew had killed her. Later Patrick returns and finds that Hannah is still alive, unties her, and brings her back to the town where she is taken to hospital. Then Matthew is convicted and sent to prison. But Hannah believes Patrick is totally innocent.
In 2008 New York City Patrick is married to Hannah in a luxury apartment overlooking Times Square in New York City. Patrick believes he should have prevented Matthew's attack on Hannah, for which he feels guilty. He has lost his job at a bank in the depression and now writes a cooking blog. Patrick feels paranoid and depressed; then he notices a proposal sent to his blog by an unknown admirer. Intrigued by the offer, he discovers it was sent by Matthew who wants to clear the air with Patrick and help him establish a restaurant in the countryside.
In a series of flashbacks, narrated by Matthew, it is revealed that prior to shooting Hannah she had seen him engage in a homosexual act with an older man. She confronts him at his house and accuses him of being a homosexual himself. MatthewâÂÂs father overhears the conversation and threatens to kill her, but doesnâÂÂt. Enraged that his son might be gay, MatthewâÂÂs father takes him for a walk in a nearby forest, gun in hand. Believing that his father is going to kill him, Mathew smashes a rock into his fatherâÂÂs head and forces his body off a cliff, killing him. Later, he confesses to Hannah that he killed his father.
Later, Matthew armed with a BB gun, Hannah and Patrick are in the woods. Patrick walks away, uncomfortable with being part of the threesome. Agreeing to play a Houdini-like game of escape, Hannah allows Patrick to tie her up to a tree. Once she is tied up, he attempts to have sex with her but she fights back. Angered by her refusal and blaming her for his fatherâÂÂs death, he grabs the BB gun and begins shooting Hannah.
It is 2008 and Hannah has discovered that Patrick was a witness to the shooting, something he has never told her. Patrick has convinced himself that Matthew is responsible for her discovering the truth and creating a rupture in their marriage. He also believes that Matthew is responsible for his being fired. Certain that Matthew wants Hannah for himself, while they are scouting rural sites for the restaurant, Patrick smashes a rock into MatthewâÂÂs head, the same type of rock Matthew used to assault his father before killing him. When Matthew regains consciousness, he discovers that he is tied up with rope. At gunpoint, Patrick forces him into the trunk of his car and drives him to the tree where Matthew had tied up Hannah many years earlier.
Hannah deduces that Patrick wants to kill Matthew. She leads police to the scene of the shooting decades earlier where they find Patrick holding a shotgun to Matthew who is tied up to the same tree. Ignoring poilice commands to drop the gun, Patrick shoots Matthew, killing him. In turn, Patrick is shot in the chest by the police. Patrick dies in HannahâÂÂs arms.
