Nathan Duncroft is a character appearing in the episode A Grain of Truth of the ITV crime drama Midsomer Murders.
Nathan works for Herron's Farm along with his dad, Jack Duncroft. They provide grain to Tom Larkton's mill.
In revenge against the mill, Denise Bantrig posted a text that the Herron's Farm was using pesticides
Tom cancelled their contract because he thought they were using pesticides under the radar. Nathan denied it. Nathan goes to talk to Chrissie about the grain contract. His dad is ill and he needs the contract. Chrissie says that Nathan made the decision to use pesticides and she doesn't want to lose their organic status. Nathan says he's always defended Chrissie in the village.
Nathan is cleaning the silo when the door is locked and grain starts coming in from above. Nathan is suffocated with grain in the silo.
Gabriel Arnson killed Nathan because he thought he poisoned Chrissie with Ergot. He didn't know that Nathan hadn't planted the Ergot
