Scotland Yard is horrified and at a loss to explain the gruesome delivery, but Sherlock Holmes sees a pattern others miss.
As Holmes and Dr. Watson investigate, they uncover a tangled web of jealousy, forbidden love, and a crime driven by passion and revenge. Their pursuit of the truth takes them from the quiet London suburbs to the depths of human emotion, revealing a shocking story of betrayal that no one could have foreseen.
A chilling and suspenseful entry in The Memoirs of Sherlock Holmes, The Adventure of the Cardboard Box is one of Arthur Conan Doyle's most unsettling yet brilliantly crafted mysteries, proving once again that nothing is beyond the great detective's deductive genius.
