Get out while you still can, Edward... while you still live... while you still have a soul.
Who: Edward Wilson’s Poetry Professor
Source: The Good Shepherd
Notes: Edward Wilson had been ordered to offer his former poetry professor, another person involved in intelligence services, a chance to resign due to his being indiscreet, but the professor refuses. The professor ties Edward’s shoes (a pre-arranged signal) and says this line before some agents, seeing the signal, kill him off-screen and dump his body in the river.
