Activity Overview
In the NUMB3RS episode "Obsession," pop star Skylar Wyatt is being stalked in her home by an intruder. Oddly, none of her home's security cameras pick up an image of the stalker. This leads Charlie to consider the placement of the home's cameras as it relates to Chvatal's Art Gallery Theorem.
