Twelve homicides, three police-involved shootings and a furious hunt for an especially brutal killer--February 2013 was a good month for murder in suburban Washington, D.C. After gaining unparalleled access to the homicide unit in Prince George's County, which borders the nation's capital, Del Quentin Wilber begins shadowing the talented, often quirky detectives who get the call when a body falls. He rides with a hard-charging investigator who pops diet pills while devouring cheeseburgers; he stands over a corpse with a hulking investigator who works security at a cemetery to earn extra money; he spends hours in the interrogation room--a.k.a. "the box"--with a chain-smoking vegan determined to solve the most difficult case of his career. And then, after a quiet couple of months, all hell breaks loose: suddenly every detective in the squad is working day and night to solve one shooting and stabbing after another. In particular, the entire unit becomes obsessed with a "red ball," a high-profile case involving a 17-year-old honor student attacked by a gunman who kicked down the door to her house and murdered her in her bed. Murder is the police investigator's ultimate crucible: to solve a killing, a detective must speak for the dead. More than any recent book, A Good Month for Murder shows what it takes to succeed when the stakes couldn't possibly be higher.
