Barry S Brown is the author of four previous novels in the Mrs. Hudson of Baker Street series. A career of research into the human condition equipped him with the skills needed to unearth the truth about Mrs. Hudson's role in London's foremost consulting detective agency. In that earlier life, he published more than 175 articles and chapters, and two non-fiction volumes dealing with mental health, criminology, and drug abuse treatment issues. No longer encumbered by such petty concerns, he devotes the time-not spent with his wife, three children, and ten grandchildren-reporting the accomplishments of the individual known to him as the woman, but to the world as Sherlock Holmes' landlady.
