Moira Moriarty calls upon the clever Sherlock Holmes, her brother James's roommate at school, to help solve the mystery of her father's death, leading them to a secret sect, a rare jewel, and a friendship torn asunder.

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.

Influence.My first challenge for the day is finding that artifact and putting it under lock and key before it kills anybody else. My second challenge is figuring out how to deal with a bossy frog and a pushy cat. Which of the two do you suppose will give me the bigger headache? Yeah. That's what I think too. The frog and cat are going to be the death of my sanity. Maybe I should put them under lock and key too.
