What can go wrong on a run on in Central Park on your last day of vacation? Even if it is brutally cold? Everyone told Detective Kristen Conner to stay inside, which guaranteed she would go outside—and stumble onto a gang murder that puts her in the cross-hairs of a Russian “Red Mafyia” hit man.

Back in Chicago, murder strikes closer to home. Just down the street from where her mom lives, a popular schoolteacher, solid citizen, and great guy—he shovels snow for widows and volunteers to work with underprivileged kids—is found dead. It was supposed to look like an accident, but crime scene investigators discover more than one killing blow to the back of his head.

When Detective Kristen Conner lands the case, she knows from day one who the key suspect is. That’s simple. The person most likely to kill you is someone close . . . someone you know and love. But his wife? The nice lady down the street. How could that be possible? Kristen is about to discover there is more violence beneath the surface of the working-class neighborhood she grew up than she ever dreamed possible.

She’s also about to discover that when the Red Mafyia wants you dead, there is no place to hide. You better be ready to fight. Mix in her on-again, off-again relationship with FBI Agent Austin Reynolds, and Kristen Conner is once again swept into a world of danger, intrigue, and a confusing love life.
