The Real World of Sherlock Holmes by Peter Costello.
Costello gives a fascinating look at Sherlock Holmes' creator, Sir Arthur Conan Doyle, and the real mysteries he investigated. Trained as a doctor, Doyle became fascinated by forensics of the day as taught by Dr. Joseph Bell. What is lesser known, however, is that average citizens contacted Doyle to help solve cases. Just like his legendary literary counterpart, Sherlock Holmes, Doyle solved cases and vindicated the innocent.
Sherlock Holmes is more popular than ever in movies and miniseries. PBS has a Fall 2013 two-hour special, How Sherlock Changed the World and the BBC has the popular Sherlock set in contemporary times.
