Lutesse

Watson stepped outside the building, heaving from the foul smoke inside from the coal and peat in Mrs. Hudson's house. Flats were unsafe to keep fires from going crazy. Suddenly Sherlock appeared dressed as a spy agent homeless man for Mycroft's new secret about government corruption. Surprised to find Watson was choking, Sherlock investigated the cause for the food that was stuck in his back molar. Afterwards, he gave Watson a pound on the back and mumbled, "Great, now I must quickly go to the underground and locate the contact who was going to assist with the extraction of important documents that would be evidence for the investigation into blackmail of certain English bulldogs." Watson called Mycroft to tell him that Sherlock went running off alone towards the tube and would possibly be in danger. Mycroft reassured Watson that he had a watcher that followed Sherlock wherever he went and would report instantly he if had encountered any danger. Suddenly angry, Mrs.Hundson scolded Watson and insisted that he would catch the flu if he continued to stand outside and let in the chill. So he decided to go inside and fetch some jackets, umbrella was optional.

Meanwhile, Sherlock had run out of the tunnel and he caught John with a gasp and told him to wear a fluffy scarf because the wind was quite strong. Thankfully some stranger began to take pictures.
