Retired DC Homicide detective Marty Singer is driving through rural Virginia when he sees a billboard by the side of the road with the picture of a man and a simple, stunning question: J.D. HOPE WAS MURDERED ON MAY 6TH. DO YOU KNOW WHY? To most, the message means nothing. But Marty stops the car, turns around, and rushes headlong into a deadly mix of drugs, lies, and double-crosses. Because Marty's got his own history with the man on the sign...and he needs to find out who murdered J.D. Hope and why if he wants to do One Right Thing. Revised edition: This edition of One Right Thing includes editorial revisions.
