Washington, D.C. homicide detective Marko Zorn takes on a far-reaching, complicated investigation when a narcotic more deadly than fentanyl spreads across the city, causing countless fatalities. His search for the people behind the off-label drug leads him to a Big Pharma company run by mysterious, psychopathic twin brothers. Anyone who crosses them is dead.

Marko discovers that the company will soon release another dangerous prescription opioid analgesic, but when the company learns that this information has been leaked, more bodies pile up. Let down by his higher-ups, Marko sets off to solve the deadly ring of crime that now surrounds him, all while evading repeated attempts to kill him.

Marko will need all his wits, skills, and contacts both inside and outside of the law to shut down the twin brothers' criminal drug empire. Can a painting from a major art theft decades earlier provide the key to how Marko can cripple the whole operation? Only if Marko isn't killed first.

Perfect for fans of David Baldacci and Daniel Silva
