> Chapter companion for The Mysterious Affair at Styles by Agatha Christie.

## What happens

Hastings visits Poirot at his cottage to recount the events of Mrs. Inglethorp's death. Poirot emphasizes the importance of every detail, even seemingly trivial ones like Mrs. Inglethorp's appetite at supper. They proceed to Styles Court, where Poirot examines the boudoir and retrieves a curious crumpled envelope from Mr. Inglethorp's desk. John Cavendish meets them and expresses concern about publicity, while Poirot cryptically remarks that the difficulty of how to treat Alfred Inglethorp 'will not exist long.'

## Key lines

> We will examine—and reject. Those of importance we will put on one side; those of no importance, pouf!—blow them away!

We will sort through the facts, keeping the important ones and discarding the trivial.

_Poirot explains his method of investigation to Hastings._

> Beware! Peril to the detective who says: ‘It is so small—it does not matter. It will not agree. I will forget it.’ That way lies confusion! Everything matters.

A detective must never dismiss a small detail, no matter how insignificant it seems, because ignoring it leads to mistakes.

_Poirot emphasizes the importance of every fact, no matter how minor._

> You have not told me if Mrs. Inglethorp ate well last night.

You forgot to mention whether Mrs. Inglethorp had a good appetite at supper.

_Poirot points out a crucial omission in Hastings' account._
