By Dr. John H. Watson Edited from the personal accounts of John H. Watson, M.D. With notes by Sherlock Holmes

On a snow-laden Christmas Eve in 1895, Sherlock Holmes and Dr. Watson receive an unexpected visitor at 221B Baker Street—one whose very existence challenges Holmes's rigid logical worldview. When the mysterious Kris Kringle reveals that Professor Moriarty has stolen a powerful artifact capable of manipulating time itself, Holmes must confront a case where the impossible and improbable collide.

As London's greatest detective races against time—quite literally—to prevent Moriarty from unraveling the fabric of reality, he discovers that some mysteries require more than pure deduction to solve. With the help of an unlikely alliance between Victorian science and Christmas magic, Holmes and Watson must save not only Christmas but time itself.

In this previously unpublished account, Dr. Watson chronicles one of their most extraordinary cases, where the boundaries between logic and wonder blur like snowflakes in a London fog. Through events that test both Holmes's legendary powers of deduction and his fundamental beliefs about the nature of reality, readers will discover that, as Holmes himself notes, "When you eliminate the impossible, whatever remains, however improbable, must be the truth."

A perfect Christmas read for fans of Sherlock Holmes and those who believe that even the most rational minds might find magic in the winter night.
