Lock and key

the long version

Before James grew up to be a ruthless, remorseless villain, he was a curious boy from Boston, with a penchant for trouble and an acid tongue. Thrown into a boarding school against his wishes, James winds up rooming with a most unlikely companion: a lanky British know-it-all named Sherlock Holmes ("Lock" to his friends). An heirloom Bible, donated by the Moriarty family more than a hundred years ago, has gone missing, and it doesn't take long for the two to find themselves embroiled in the school-wide scandal. The school is on lockdown until it's found, strange clues keep finding their way to James, and a secret society lurks behind it all.
