The deadly hand of Professor Moriarty once more reaches out to commit a vile and ingenious crime. However, a mole in Moriarty's frightening criminal organization alerts Sherlock Holmes of the evil deed by means of a cipher. When Holmes and Watson arrive at a Sussex manor house they appear to be too late.
Sir Arthur Conan Doyle (1859-1930) started to write as a doctor, whilst waiting for patients to arrive. Sherlock Holmes first appeared in A Study in Scarlet (1887). The Holmes stories soon attracted such a following that Conan Doyle felt the character overshadowed his other work. In The Final Problem (1893) Conan Doyle killed him off, but was obliged by public demand to restore the detective to life.
