Guess Who: A Novel in Bloomington, MN

The rules are simple.
But the game is not.
At eleven years old, Morgan Sheppard solved the murder of a teacher at his school. The publicity surrounding the case launched him to fame as a modern-day Sherlock Holmes.
Until, that is, Sheppard wakes up handcuffed to a bed in an unfamiliar hotel room. Around him, five strangers are slowly waking up, as well. Soon they discover a corpse in the bathtub. But which one of them is the murderer? Now Sheppard must put his deductive skills to the test—or face certain death.
