Martin Dakin has ferreted out more facts and gone a long way to explaining the still unexplained in the Sacred Canon. Who for instance was the mysterious power behind the sinister Joseph in The Naval Treaty? What was the secret of Holmes's visit to the 'worst man in London'? These are typical problems that Martin Dakin unravels or at least puts us on the path to solving.

Just as Inspector Baynes confessed to Holmes, 'I thought I had squeezed all the juice out of it but, it seems, there was a little over,' so it seems this book offers another generous measure of delight for the thousands of admirers of the greatest detective in the world. There are full references, a bibliography and an index.
