"Before James Moriarty and his sister Moria enrolled in Baskerville Academy, they were inseparable--as close to best friends as a brother and sister could be. But since setting foot on the boarding school's campus, James has been different. At Baskerville, he's become cunning, deceptive, ruthless, sometimes reckless. And now that his roommate Sherlock Holmes has been expelled, there's no one left to help Moira figure out what's going on with her brother or to uncover the connection between a recent string of deaths. To Moria, it seems obvious that someone has it out for the Moriarty family. First their father and then their family driver and now their legal guardian--clearly something is afoot. But to get the answers they need, they'll first have to deal with an incriminating photograph, secret safe houses, and powerful enemies." -- Amazon.com.
