The victim-biting serial killer Colville appears to be up to mischief again and to have murdered two women. However, Colville is already dead. Sherlock and Watson are puzzled and question Watson's colleague Dr. Fleming.

Root questions Weeks, one of the few men who knows of the Machine's existence, about where it is, and kills him afterwards. Meanwhile, Reese and Carter go to Texas to investigate the girl who disappeared a few years ago.
