A woman who sees what others cannot see seeks the murderer of a young street hustler, a man she had befriended in photographing San Francisco's dark, sexually charged netherworld. The colors of Kay Farrow's landscape are black, white, and shades of gray. An achromat suffering from total color blindness, Kay possesses a vision that informs her world and sharpens her skills as a talented photographer. When Tim Lovsey, a handsome prostitute, is brutally slain, he becomes much more than Kay's subject. She makes it her mission to find his killer, even though the police would prefer to quietly let the case drop.
Kay Farrow, a color-blind photographer who sees the world in black, white, and shades of gray, probes the mysterious death of her beloved mentor on a quest that takes her to the darkest intersections of San Francisco's Mission District. When distinguished photojournalist Maddy Yamada is struck by a motorcyclist at two in the morning in a seedy area far from her Marina apartment, Kay Farrow's grief is tempered by suspicion. What could have drawn the reclusive Maddy so far from home at such an hour?
