Definition of Foreshadowing
The Sign of the Four is a mystery novel whose main character, Sherlock Holmes, is extremely good at unraveling mysteries. Given the accuracy of Holmes's observation skills and deductive reasoning, nearly everything that Holmes comments or observes throughout the story foreshadows a revelation later.
A small but significant early example comes in Chapter 2, when Holmes observes that the letter Mary Morstan has received and the address of her pearl-box are in the same handwriting:
'They are disguised hands, except the letter,' he said presently; 'but there can be no question as to the authorship. [...] They are undoubtedly by the same person."
