10. What colour was Mrs. Inglethorp's despatch case?
From Quiz The Mysterious Affair at Styles
Answer:
Purple
When Poirot is brought to investigate, he finds it of extreme importance to pay a visit to Mrs. Inglethorp's bedroom. Here, he outlined the evidence that he was able to find.
1. A coffee cup, ground to powder on the floor.
2. A significant purple despatch case with a key in its lock. This case contained Emily's important papers.
3. A stain on the floor, which is found to smell like coffee.
4. A fragment of fabric retrieved from the bolt of a door, assumed to be locked at all times, connecting Mrs. Inglethorp's room with Cynthia Murdoch's.
5. A splash of white candlewax on the floor.
6. An unmarked chemical box used for bromide powders, found on Mrs. Inglethorp's nightstand. It is later discovered that Cynthia made these for Emily. With her medical background, she did not need a pharmacist or chemist's seal on the box; they were used as sleeping agents.
After listing his finds, Poirot also finds a scrap of paper, found to be from a will, in the ashes of the fireplace. Hastings and Poirot discuss the matters with Dorcas, who claims that Mrs. Inglethorp argued with an unknown man in her bedroom the afternoon before, and that she was missing the key to her despatch case. As well, another maid claimed that she found an odd salt-like substance on Emily's serving tray with her cocoa. Hastings realizes that it may be strychnine poison.
