The mantle of immortality is illusive, and unpredictable. Two fictional characters, created at the turn of the century by Sir Arthur Conan Doyle have become undying legends. So strong is the public belief in their existence, that the city of London recently granted the owner of the premises at 221b Baker Street, the right to change the number of that address permanently in order to avoid the hordes of tourists flocking to see the actual living quarters of Sherlock Holmes and his colleague Dr Watson. Our story today starts in those very rooms, in the year 1902.
