“Would a master spy really have been caught twice sneaking into a dead woman's home? Not unless he wanted to.” — Carter Roy (1:08:15)

Quote:

“For him, all this fuss about finding it was probably well worth it. He had to protect the CIA and himself. It was the smoking gun. And by extension, he had to kill the owner of that gun.” — Carter Roy (1:13:38)
