1907. A mysterious criminal known as Fantomas terrorizes London. Only Sherlock Holmes believes in his existence, and he has begun laying the groundwork to arrest him, but Fantomas strikes first, and murders the Great Detective in circumstances that point suspicion at an innocent man. A young Harry Dickson and Sherlock Holmes' niece, Emily, must expose Fantomas before Scotland Yard sends her fiance to the gallows. This never-before-translated play was initially performed in Belgium in 1914 for a few weeks before World War I began and has never been restaged since. The play was translated and adapted by Frank J. Morlock, author of Sherlock Holmes: The Grand Horizontals in which Holmes also crosses swords with Fantomas. The book includes an introduction, afterword and chronology of Fantomas by Jean-Marc Lofficier.
