# XIV: Ada Mason's Story explained — The Mystery of the Blue Train

> Chapter companion for The Mystery of the Blue Train by Agatha Christie.

## What happens

In the Examining Magistrate's room at Nice, M. Carrège, the Commissary, and Van Aldin are joined by Hercule Poirot, who offers his assistance. They interrogate Ada Mason, Ruth Kettering's maid. Mason describes how, at the Gare de Lyon, Mrs. Kettering met a tall, dark gentleman and abruptly changed plans, sending Mason to the Ritz in Paris while she continued on the train. Mason confirms that her mistress left her jewel-case, containing valuable rubies given by Van Aldin, on the train. After Mason departs, Carrège reveals a letter found in Ruth's handbag, addressed to 'Chère Amie' and signed 'Armand,' which mentions the rubies and a planned rendezvous at the Isles d'Or.
