Bond meets a woman who is a Greene insider. She is right next to the man he’s trying to find out about, the man he believes is connected to White.

Not only is she a great source, but she’s a natural ally. She’s just found out that Greene has been plotting to kill her, so her loyalties must shift. Bond is perfectly placed to be the new recipient of those loyalties.

Then she’s knocked unconscious, and he can easily help her, rescue her, and get on her good side. She’s the perfect source, everything a spy needs.

So what does he do? Dump her.
