Throughout the end credits, the action follows a horsedrawn sleigh en route to an unknown destination. In last shot, the audience becomes privy to the surprise identity of the passenger, a key figure in Sherlockiana.
Before the end credits roll, there is a note that the film was an affectionate speculation on Sherlock Holmes' youth, and not based specifically on any of Arthur Conan Doyle's works: "Although Sir Arthur Conan Doyle did not write about the very youthful years of Sherlock Holmes and did establish the initial meeting between Holmes and Dr. Watson as adults, this affectionate speculation about what might have happened has been made with respectful admiration and in tribute to the author and his enduring works."
[opening credit] The following story is original and is not specifically based on the exploits of Sherlock Holmes as described in the works of Sir Arthur Conan Doyle.
