The Street Lawyer by John Grisham

Michael Brock is in a hurry. He`s in the fast lane at Drake and Sweeney, a giant Washington law firm. He`s a rising star, with no time to waste, no time to toss a few coins into the hands of beggars. No time for a conscience. But a chance violent encounter with a homeless man stops him cold. The fallout propels him onto a trail of corruption and illegality which leads straight back to Drake and Sweeney. To get to the truth, Michael will have to dig deep into some of his own firm`s dirtiest secrets.
