Aaron Hotchner:
Then I have to ask you, how do you know she's missing?

Dr. Spencer Reid:
Because we always addressed our letters to our pseudonyms.

Aaron Hotchner:
And you're Dr. Joseph Bell?

Dr. Spencer Reid:
The real-life inspiration for Sherlock Holmes. And that codename is how I know she's in trouble. The voice on the phone identified himself as Adam Worth. That was the American criminal that Arthur Conan Doyle based the character of Moriarty on.

Aaron Hotchner:
And what did he say to you?

Dr. Spencer Reid:
Zugzwang. It's a chess term. It describes the point in a game when a plyer realizes he'll inevitably be checkmated. He has to decide whether to resign or play through the bitter end.

Aaron Hotchner:
If you're right about this, then you're part of his victimology, too.

Dr. Spencer Reid:
I know. He thinks he'll get away with this, and he might. I have a wealth of knowledge I should be applying to this case. Behavioral patterns of violent stalkers, tactical recovery strategies, victim survival odds. But right now I can't focus on anything for more than four seconds at a time, which makes me the dumbest person in the room. So... Please help me. Help me find her.
