Twenty-four years ago, sixteen-year-old Laurel Wynn died at Alder Lake. The official finding was simple: a tragic accident after a night of drinking with friends. The people who were there moved on, building careers, reputations, and comfortable lives while Laurel became little more than a name in an old police file.

Then Graham Tolland is found dead at the Bellweather, and Detectives Mara Vance and Reid Calder discover something deliberately left beside his body—a message pointing them toward a death no one has questioned in decades.

When another person connected to the death at Alder Lake is murdered, the pattern becomes impossible to ignore. Someone knows what happened to Laurel that night, and they are forcing the past back into the lives of those who survived it.

As the bodies mount, Mara and Reid uncover contradictions buried beneath twenty-four years of silence. The people who were at Alder Lake remember more than they admit, but separating fear from deception becomes increasingly difficult when every answer exposes another lie.

Someone has waited a long time for the truth to surface.

Someone is playing a Dead Letter Game.

And they aren’t finished yet.
