An illustrated adaptation of Sir Arthur Conan Doyle's classic Sherlock Holmes mystery - at an easy-to-read level for readers of all ages! 'This is not danger. It is definite destruction. Even with all your cleverness, you do not realise it. You must stand clear, Mr Holmes, or you will be crushed underfoot.' Holmes is facing a problem - a big one. He's on the tail of his most dangerous criminal to date, Professor Moriarty. But it seems that the professor is one step ahead. Can the detective unwind Moriarty's web of crime before it's too late? Or could this really be Holmes' last case?
