Criminal Minds Episode 8.12 Zugzwang

After receiving a phone call from someone disguised by a computerized voice that just contains the word 'zugzwang' - a German chess term for when you know you've been beaten but you still need to decide if you're going to play out the rest of the game - Reid realizes that something terrible has happened to Maeve. Enlisting the rest of the team for help, Reid attempts to rescue his girlfriend from her stalker before it's too late.
