When tragedy strikes, a cold case suddenly turns hot—and deadly. A peaceful morning is shattered when Washington Metro Police lieutenant Sam Holland’s beloved father succumbs to injuries from an unsolved shooting while on duty four years ago. As the community rallies around Sam and her family, one thing becomes crystal clear: her father’s death has turned the unsolved case into a homicide—and it’s on her to bring her father’s killer to justice. But the case has been cold for years…until an anonymous tip that’s too shocking to believe leads Sam down a dark and dangerous path. Her husband, Vice President Nick Cappuano, knows if she can’t solve this case, it will haunt her for the rest of her life. She’ll need the strength of their bond to pull her out of the darkness before it’s too late, because as the missing pieces rapidly fall into place, Sam realizes the truth might just break her all the same—and that her father’s killer isn’t done yet…

A deadly serious affair… The story breaks as Metro PD lieutenant Sam Holland attends a dinner party with her husband, Vice President Nick Cappuano: President Nelson is accused of having an affair. More shocking still, campaign staffer Tara Weber claims the president fathered her newborn son—while the First Lady was undergoing secret cancer treatment. When a high-profile murder case hits Sam’s desk, she’s shocked to uncover a connection to the presidential scandal. With the department caught up in its own internal scandals, and the chief’s job hanging by a thread, Sam questions who she can trust as her team uncovers information that clouds an already-murky case. And with calls for the president to resign getting louder by the minute, Sam needs to close this case before she finds herself living at 1600 Pennsylvania Avenue.
