Pick Your Poison (слэш)

In a world with no magic, Harry Potter is dragged along to galas and events to serve as a pretty face beside his schmoozing Uncle Vernon. Tonight's gala promised to be as miserable as the last - until Harry notices a member of the Minister's secret police slipping poison into the glass of Thomas Riddle; leader of an underground criminal operation.
Thrown into a world of politics, assassination attempts and devastatingly handsome aristocrats, Harry must decide to fight for what's right . . . or succumb to his fatal attraction.
