Former soldier Michael Freeman is now a homicide detective in Washington, D.C. As a huge snowstorm engulfs the city, a late-night jogger in Rock Creek Park discovers the brutally beaten body of a once beautiful young woman. She is lying just yards from the palatial home of Senator John Cannon - one of the most powerful and wealthy men in America.
It's clear that Freeman has a delicate case on his hands, and the investigation takes him relentlessly into ever more dangerous territory, like Germline BioSciences - a secretive, cutting-edge research facility funded by the Department of Defense.
And what of the mysterious midnight jogger in Rock Creek Park?
Is it really just a coincidence that Scottish bodyguard Harriet (Harry) Armstrong is now working for Germline's Russian director?
With the body count escalating, Freeman and Harry are swiftly drawn into a shadowy world of secrets and conspiracies more shocking than anything either of them could have imagined.
