The 'thoughts' in this book are the fruit of nearly ten years spent studying the canon and the life of Sir Arthur (Ignatius) Conan Doyle, writing two pastiches (The Sign of Fear and A Study in Crimson), a Biography of Doctor Watson and A Sherlock Holmes Who's Who. In it readers will find much to entertain, along with enough out of the way information to interest even the most knowledgeable Sherlockian. For those new to the iconic pair I have tried, as far as possible, to present material which will make them want to read more about the man and his doings and perhaps become fervent Sherlockians themselves.
