Sherlock Holmes The Dark Adagio

"Scotland Yard has kept me out of the Ripper Business and even the men who looked the other way so that I could inspect a scene, are afraid to speak to me," Holmes said. "I stand here at this window and look down on Baker Street. The whole world passes by us in a single day. There goes an American, a dentist from Idaho, lost in London. He has no idea that Sherlock Holmes is watching him as he hurries past. There is a brush salesman from Coventry. He goes hopefully door-to-door. And just here, across the street, in front of the dun-colored house...I say, he's watching me."
So began the case of "The Dark Adagio," an adagio in ballet being a complex dance performed by a man and woman or by a mixed group of three. It was the fall of 1888 and the macabre Whitechapel Murders had just been transformed, by the receipt of a letter in red ink, into "The Jack the Ripper Killings."
The Yard, as Holmes had said, had made him a pariah, threatening the jobs and careers of anyone who dared work with him.
Watson still trusted the nation's institutions and viewed the business a miscarriage of bureaucratic power. Only Holmes knew it was more than that.
Then the man across the street appeared with his dark mystery, one which only Sherlock Holmes could solve, and suddenly everything changed.
