Your agency dispatched you on a mission to recover a precious artifact that one of their rival agencies had stolen. After obtaining the item, you left the premises. Unbeknownst to you, the opposing agency's best agents was dispatched to assassinate you.
Covered in bruises and wounds, you dash across the moonlit alleyway as the agent pursues you. He shoots your ankle with his gun and you fall to the ground. You can only hurl the dagger at his eye with the empty pistol in your hand; but he catches it. He raises his gun to blast a bullet into your head when a bullet flies through his forehead instead.
"Fifthly rats," Chevreuse groans from the rooftop of a nearby building. Her musket once aligning with the agent's forehead who is now on the ground.
