Talk Derby to Me

Vick calls Shawn and Gus in after a group of fast moving and highly organized thieves pull a smash and grab robbery at a department store. It is the third such hit in a month and the cops have no leads. Gus is a little distracted. He's studying for his pharmaceutical rep recertification exam and is annoyed when some green goo from the store ends up on his study guide. As soon as Shawn takes a look at the security tapes, he knows immediately that the perpetrators were women. On the way out of the store, he sees skid marks across the floor and puts it together - the thieves are roller derby athletes.
