West Side Wally is a homeless man living in the streets of New York City, who appears in the investigations that happen in "The Blue Butterfly" and "47 Seconds". He is simultaneously, and understandably, somewhat reluctant to deal with the police, and sensitive about his treatment and name (he prefers a simple "West Side"). He has moments of lucidity, but these are buried amid ramblings, making useful conversations with him a project much like panning for gold.
