On the night of October 15, 1977, Officer Cordelia “Kora” Blackwood of Moonrise Bay, California, disappeared during a routine patrol. Her cruiser was later found shattered at the base of Devil’s Tooth Cliff, waves crashing mercilessly against the wreck. But her body was never recovered.

For thirteen years, the case haunted the seaside town. Cordelia was not only their first and only female officer but also one of their most respected. Her disappearance was never accepted as an accident by her sister, Maple Blackwood, who refused to stop searching. Each October, she returned to the cliff with flowers and a vow: I’ll never stop looking for you.

Cordelia’s final night began like many others. She answered a call about a disturbance at a local diner and then reports of strange lights near Devil’s Tooth Cliff. Moments later, her last transmission came through. Hours after, her car was discovered wrecked on the rocks below. There were no signs of a struggle inside the diner, only overturned chairs and a warm cup of coffee. Witnesses later recalled odd details, like seeing Cordelia nervous in her final days, feeling watched. Some even spoke of a mysterious man with pale eyes seen near the cliff.

The investigation was exhaustive. Search teams combed beaches, forests, and coastlines. The FBI was called in. Residents volunteered day and night. Yet every lead dissolved into dead ends. Moonrise Bay was left with a gaping wound, and Maple Blackwood’s obsession with finding answers grew into a defining part of her life. She created a memorial at the town library, founded a support group for families of the missing, and became a beacon of resilience in the face of tragedy.

Then came March 15, 1990. A storm unlike any in 50 years ravaged Moonrise Bay, tearing apart the harbor and battering the cliffs. When dawn broke, locals noticed something new: the storm had ripped open the face of Devil’s Tooth Cliff. Where once was solid rock now yawned a dark cavern.

Investigators lowered themselves inside. What they found changed everything.

Cordelia’s police badge lay among debris, rusted but unmistakable. Scattered around were traces of human confinement—chains, broken restraints, remnants of clothing belonging to people long missing. The cave bore evidence that at least 14 individuals had been held there over three decades.

But one discovery chilled even the most seasoned officers. Freshly carved into the cave wall were the letters “MB1 1990.” Maple Blackwood’s initials, etched only months earlier, suggesting that whoever had taken Cordelia had not only continued their crimes but had marked Maple as the next victim.

This revelation transformed Cordelia’s disappearance from a haunting mystery into the uncovering of a decades-long nightmare. Someone had been hunting people in Moonrise Bay, hidden in plain sight, using the cliffs and caves as their lair. And they had marked their next target long before the storm revealed their secret.

For Maple, the discovery was both vindication and horror. She had been right all along—Cordelia had not vanished by accident. But now she faced the terrifying truth: whoever had taken her sister was still out there, and she was in their sights.

Moonrise Bay was left reeling. A quiet coastal town suddenly became the epicenter of a chilling revelation. Who was the predator that haunted their community for decades? Why had they targeted Cordelia? And why had Maple’s name been carved as a warning?

The answers remain buried in shadows, but one thing became clear that day: the storm didn’t just tear open the cliff. It tore open the darkest chapter in Moonrise Bay’s history.
