The Firefall

A vandal's final act in Yosemite National Park uncovers a hidden message—and a deadly legacy.

When a graffiti artist defaces part of Yosemite National Park, Special Agents Clarence Johnson and Alison Nance expect a straightforward case. But when the suspect falls to her death from Glacier Point—just as another member of her synagogue did years earlier—the investigation takes on a far more ominous meaning.

The eerie coincidence hints at a deeper, darker truth behind the artist's final work. As Johnson and Nance unravel the layers, their search points to a historical puzzle stretching back to 1938, when a Jewish violinist, fleeing the shadows of Nazi Germany, disappeared into the park's vast wilderness, carrying a secret that could alter the course of history.

Decades later, the past refuses to remain hidden. The agents begin to link the contemporary murder to the long-unsolved disappearance and a mysterious legacy hidden in Yosemite's rugged terrain. But as they close in on the truth, they realize they are not the only ones searching. A relentless adversary is also on the trail, willing to kill to claim the secret and reignite a dark chapter of history. Now, Johnson and Nance must outwit a ruthless enemy before history's darkest forces rise again.

In The Firefall, Mark Thielman delivers a gripping tale where history's buried secrets collide with a modern-day investigation. With a masterful blend of mystery, suspense, and historical intrigue, this dual-timeline thriller is perfect for fans of Steve Berry and Gary McAvoy.
