How does the author use foreshadowing in Curtain?

In Chapter One, Captain Hastings foreshadows that a mystery unfolds while he and Hercule are staying at Styles. As the Captain meets each of the house guests, it reveals the characters that will be involved in the mystery that Poirot tries to solver while they are staying at Styles. The fact that Hastings's daughter, Judith, lives on the property also suggests that there will be some family issues that come into play in the story line.
