File 5. In the fall of 1920, Sir Arthur Conan Doyle is summoned to the county of Cumbria in northwest England to investigate a number of strange occurrences at Dryden Manor, including the mysterious death of its former caretaker. Perched at the edge of a remote and secluded lake, Dryden Manor’s eccentric architecture hides a secret the world-famous author is determined to understand. As soon as he sets foot on its impressive grounds, the author senses that something is amiss. Together with a private detective, the latter’s sleuthhound Watson, and a feisty female spiritualist, Doyle investigates the nocturnal screams, the frightful apparitions, and the countless blowflies that infest the eerie house. What he unearths is nothing less than evil incarnate.
