Detective Susan Ford notices a missed call on her phone from a number she doesn't recognize, and when Madison Garcia, a woman with past ties to the town of Monticello, New York, is found stabbed to death the next morning, Susan realizes that Madison was the one who had called her. But why?

Susan teams up with her father, retired Detective Will Ford, to find the killer, and their investigation soon threatens to uncover Madison's family secrets--an inheritance, accidental death, money laundering, extramarital affairs, and family rivalries, just to name a few--and they don't appreciate the Fords digging into their business.

As the investigation twists and turns, the Fords discover that Madison was planning to confess to a long-kept secret, but someone brutally silenced her. Everyone she knew is a suspect. Anyone could be her killer.
