Fedorovich File — Ross H. Spencer

The Chicago PI is out to find a Russian defector with dangerous Soviet secrets in this hardboiled mystery from the author of Death Wore Gloves.
 
When business gets too hot in the Windy City, private detective Lacey Lockington hangs out his shingle in refreshingly boring Youngstown, Ohio. Of course, it's not all boring thanks to Natasha, the former KGB agent who saved his life, stole his heart, and currently shares his bed. But their brief idyll ends when Lacey is offered big bucks to find a man who may well be hiding out in Youngstown.
 
Alexi Fedorovich was one of Russia's greatest military minds before he defected to the States -- and then disappeared entirely. Before going underground, he published a book exposing the end of the Cold War as a Russian hoax. Now Lacey's out to find a man who doesn't want to be found, up against Russian spies, federal agents, and leads that keep dying on him. With a little help from Natasha, he might just get to the bottom of it all before Fedorovich finds himself on the wrong end of a firing squad.
