How does the author use foreshadowing in London Bridges?

In Part II, the Wolf laments his belief that no one understands him, a common cry of the criminal mind. There is a hint here of the reason for his paranoia and criminal acts, a mention of Paris, a foreshadowing of things to come. Once again there is a reference to the little black ball - a key to everything about the Wolf. His thought, Revenge, a dish best served cold, is a foreshadowing and the theme of this man's entire purpose in this story.
