Darth Sidious has expertly hidden his existence from the Jedi for many years. In Labyrinth of Evil, his elusiveness shines towards the end of the Clone Wars as his identity is being chased by Obi Wan Kenobi and Anakin Skywalker.

While Anakin and Obi Wan are occupied with their intense mission, Count Dooku and General Grievous work on setting their master's next plans into motion. Author James Luceno uses this opportunity to offer us the backstories of these two villains before foreshadowing Anakin's fall to the dark side.
