When Grace Lee storms into the Dark Falls Police Department, heads turn. But she only has eyes for Detective Nate Ryder—the officer who closed her brother Jimmy’s case too quickly, declaring his death a suicide rather than a murder. As a forensic scientist, Grace thinks the signs are obvious, the trick is convincing Nate.
Nate has to admit Grace’s argument makes a lot of sense, and he feels obligated to revisit the case. The problem is, while he’s following the old evidence, she’s collecting new samples—and putting herself in danger from the same organization that killed her brother. Jimmy was definitely onto something before he was murdered. Now, Nate has another worry: some of the new evidence Grace has found points back to members of the Dark Falls PD.
As strange coincidences turn deadly, Nate has to become Grace’s protector. They don’t know who they can trust and who they can’t. Will Grace and Nate be the next victims in a massive cover-up? Or can they figure out which cops are dirty fast enough to stay alive?
