From the cold-blooded murder of a man well known in London's Bohemian society, to a sinister tradition in an old Tudor manor-house, these six cases, from the early years of Holmes's career in the 1880s, present a singular collection of mysteries for the world's first consulting detective to resolve.

Who is it that bangs on the front door of Mr Lidington's isolated cottage in the dead of night? Why does Henry Barton's job interview proceed in such a surprising and unpredictable way? What is the secret of the man from Chile and his strange, silent wife? Sherlock Holmes must find the answers to these and many other puzzling questions if he is to bring these cases to a successful conclusion.
