Who narrates Agatha Christie's novel 'The Moving Finger'?

Agatha Christie's The Moving Finger is narrated by Jerry Burton.

Jerry is a wealthy former pilot whose flying career has been curtailed by a serious injury. He moves with his sister Joanna to the Devon village of Lymstock, where the siblings become targets of anonymous letters accusing them of an improper relationship. Jerry recounts the events in the first person, giving the novel a personal, observant perspective.

Although the book belongs to the Miss Marple series, Miss Jane Marple is not the narrator. She enters the investigation as an amateur sleuth whose understanding of human behaviour helps expose the truth behind the letters and the crimes connected with them.

Readers sometimes confuse Jerry with Luke Fitzwilliam, who narrates or features prominently in other Christie mysteries, or assume that Marple narrates every novel bearing her name. The Moving Finger was first published in the United States in 1942 and in Britain in 1943.
