Sadie Carson is an expert on unfinished business. Five years after the derailment of her dreams she's just barely existing, using her job as a hospice nurse to give others the one thing she can't seem to find-closure. So when her elderly neighbor Charlie, a brilliant conspiracy nut known for harassing the FBI, is murdered, Sadie suspects Charlie might've been onto something and intends to make sure someone solves the mystery of her friend's death, even if it's her.

The feisty little blonde may have found the victim's body, but FBI Special Agent Archer Hayes has no intention of letting some nosy civilian interfere with his investigation. The guilt he feels is bad enough. The last thing Archer needs is another distraction to haunt him. Especially one as beautiful and beguiling as the girl next door.

But throw in a mountain of hoarded evidence and suspiciously coded journals and the case takes a puzzling turn toward a decades old conspiracy cover-up from World War II-one only the victim's closest confidant can help untangle. Sadie and Archer reluctantly join forces to decode the riddle of secrets Charlie carried to his grave. Or did he? Someone is after a dangerous truth. But to uncover it or bury it is a question that leads the unlikely pair on a quest for redemption that lands Sadie in the crosshairs of a desperate killer. And when the dangers of the past and present collide Archer must fight to save the woman he's falling for...only to need saving himself.
