The Sign Of Four

"The Sign of Four" is the second novel featuring Sir Arthur Conan Doyle's iconic detective, Sherlock Holmes, and his friend Dr. John Watson. Published in 1890, this mystery novel weaves a complex tale of love, betrayal, and colonial treasure. The story begins when Mary Morstan seeks Holmes's help in solving the mystery of her father's disappearance a decade earlier and a mysterious gift of pearls she has received each year since. The investigation reveals a twisted tale of a stolen treasure, a pact between convicts, and a secret pact symbolized by the "sign of four." The chase through London, a climactic boat chase, and Holmes's deductive powers make this an engaging read.
