The Third Silence — Nancy Springer

What starts as a typical day for self-described arts nerd Brad Litwack is soon altered by a woman who stops a car in the middle of traffic and begins to paint poetry all over it. Brad is immediately intrigued, particularly by the phrase "Dario Fuentes," something his police officer father seems particularly outraged about when he arrives on the scene to take the woman to jail. Although his father insists Brad keep his nose out of the situation, Brad can't help but do some research to find out what message the woman was trying to convey. What Brad uncovers is a dark family secret, every bit as intriguing as the poetry-covered car itself. A short story.
