Tanya Barrett (Elementary)

Tanya Barrett (Lynn Collins) is the main villainess from "Solve for X," episode 2.02 of Elementary (airdate October 3, 2013). She is a mathematics professor at TriBoro College, as well as the revealed murderous mastermind of a plot to steal billions of dollars. 
Tanya's evil plan included the notorious unsolved problem, P vs NP, which--if solved--could crack cryptography systems from the world's banks, allowing Tanya to rob them all. Sherlock originally believed that Tanya was looking to solve the problem before math tutor Felix Soto and reclusive savant Cyril Nayer could. In actuality, Tanya solved the problem weeks ago, but she was looking to keep the solution a secret, or else the banks would change their systems to make them more secure. To do so, the evil Tanya hunted down Soto and Nayer and killed both of them, doing so via gunshots.
Tanya's accomplice, Wayne Kaneshiro, worked on a computer code to implement the solution, and also tampered with the security video to make it appear that their meeting at a pub occurred during the murders. After her confrontation with Sherlock, Tanya was arrested and taken into government custody.
