The rules are simple.

But the game is not.

At 11 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.
