Louise Bourget

"Naturally, if I had been unable to sleep, if I had mounted the stairs, then perhaps I might have seen this assassin, this monster, enter or leave Madame’s cabin, but as it is — Monsieur, I implore you — you see how it is? What can I say?"

- Louise Bourget to Poirot; note the use of "if" and "perhaps" in her sentence that implied she was lying

Louise Bourget is a minor character and the third victim in Agatha Christie's Death on the Nile. She is the maid of Linnet Doyle, the novel's first and primary victim. She was questioned by Poirot after the death of the Linnet, due to possibilities for her to witness the murder.

However, like many other victims in Agatha Christie's novels, she can be considered as a villainous victim after her true nature was revealed to be a greedy liar who attempts to gain profits from the murder. She was later killed by the culprit for meddling their plans.

She was portrayed by Jane Birkin in the 1978 adaptation and by Félicité Du Jeu in the 2004 adaptation in Agatha Christie's Poirot.

Overview
Louise witnessed Simon Doyle murdering Linnet, but she chose to blackmail Simon with it and lied to Poirot that she never saw the murder, resulting in a confusion on Poirot and Colonel Race's investigation upon the case. Louise soon became victim of Jacqueline de Bellefort when Poirot had discovered the oddness in Louise's testimony, which frequently used "if" and "perhaps".

Mrs. Otterbourne witnessed Jacqueline entering Louise's cabin before stabbing her, but was killed by Jacquelin before she had the chance to warn Poirot.
