Detective Jackson of the Neopolis Police Department is synaesthesic--that is, she perceives sound, sight, taste, touch, and smell in unexpected ways. For instance, she senses a sound as a color and a color as a sound.

In other words, she can "hear" colors and "see" sounds and so forth. Her distinctive interaction with the world makes her a uniquely perceptive investigator. She can detect things more strongly than a non-synaesthetic, and her seemingly convoluted impressions are lasting, making her a truly dogged detective.
