 An interview and profile of Adrian Conan Doyle, son of Sir Arthur Conan Doyle, creator of Sherlock Holmes. The younger Doyle is the trustee of his father s literary estate and at the time of the interview, lives in a 10th century castle just north of Lausanne, Switzerland (except in the summers, which he spends in Nice, France). He is an authority on his father s life and accomplishments, which extend well beyond his literary creation.
