The Final Problem

"My dear Watson, Professor Moriarty is not a man who lets the grass grow under his feet. I went out about mid-day to transact some business in Oxford Street. As I passed the corner which leads from Bentinck Street on to the Welbeck Street crossing a two-horse van furiously driven whizzed round and was on me like a flash. I sprang for the foot-path and saved myself by the fraction of a second. The van dashed round by Marylebone Lane and was gone in an instant. I kept to the pavement after that, Watson, but as I walked down Vere Street a brick came down from the roof of one of the houses, and was shattered to fragments at my feet. I called the police and had the place examined.
