HP: Ordered to Betray the Dark Lord

I am Lucius Malfoy, the Dark Lord's most "loyal" servant.

They think I have submitted to power and fear, but they do not know that I kneel only to protect the one vulnerability I have left, hidden in the shadows.

When the Cruciatus Curse tears away the last of my dignity, admiration appears in the Dark Lord's red eyes:

"One honest opportunist is worth more than ten thousand fanatical fools."

From then on, I am ordered to eliminate rivals, scheme and maneuver, and even... plan the perfect betrayal against him.

When my wand finally points at the master I once served, will he remember that he was the one who turned me into his deadliest enemy?
