A Firing Offense — George P. Pelecanos

As the advertising director of Nutty Nathan's, Nick Stefanos knows all the tricks of the electronics business. Blow-out sales and shady deals were his life. When one of the stockboys disappears, it's not news: just another metalhead who went off chasing some dream of big money and easy living. But the kid reminded Nick of himself twelve years ago: an angry punk hooked on speed metal and the fast life. So when the boy's grandfather begs Nick to find the kid, Nick says he'll try.
