“One of the blissful ways of passing an evening, when you encounter another dyed-in-the-blood addict, is to embark on the happy discussion of minor details of Holmesiana. “Whose gold watch was it that had been so mishandled?” one may ask; and the other counters with “What was the book that Joseph Stangerson carried in his pocket?” Endless delicious minutiae to consider! […]Or there are the glimpses of Moriarty to be talked over: his youthful treatise on the binomial theorem “which had a European vogue”. Or Mycroft Holmes, seven years older than Sherlock: we would gladly have heard more of him and of the Diogenes Club. How was it that Dr. Watson happened to cherish a portrait of Henry Ward Beecher, but never had it framed? Or we might air a minor grievance that the devoted Mrs. Hudson had never been implicated in a mystery of her own. There was a mystery about a landlady, but a certain Mrs. Warren was brought in for the purpose. And why did Gregson and Lestrade gradually fade out of the picture? Why does Billy the page boy remain only a phantom? Holmes speaks once of being at college: what college was it? And Dr. Watson’s wound from the “Jezail bullet”: was it in his shoulder or his leg: apparently Sir Arthur was not quite sure.”
