Chilworth

A worker from Chilworth was one of the first to search Agatha Christie's car before police were called. They said that at first they thought it had been stolen and dumped near the lake. When told it belonged to Agatha Christie they said they'd never have believed it. (TV: The Unicorn and the Wasp)

Behind the scenes
As we know that The Unicorn and the Wasp takes place in Surrey, the Chilworth mentioned in The Daily Courier is most likely the real world Chilworth Manor.
