In "Spree", two lovers have committed a series of crimes at various locations. Agents Eppes and Edgerton have plotted a map of their movements and have enlisted Charlie's help in trying to detect a pattern. Charlie says that the map shows only half of the story, and this pattern 'is a variation of something called a pursuit curve, created when one point chases another'. In this activity, students will study a pursuit curve problem modeled by four bugs chasing one another.
