The Eldest Detective

Some mysteries don't die. They wait. At seventy-eight, legendary detective Elias Thorne has spent years hiding from the ghosts of his past-and from the one case he could never solve. But when a desperate young woman asks for his help finding her missing brother, a brilliant scholar obsessed with ancient texts and forgotten societies, Elias is drawn back into a world he thought he had left behind forever.
The clues lead to the Serpent's Coil, a secret society believed to have vanished centuries ago, a mysterious artifact of unimaginable power, and a chilling symbol Elias has seen before-at the scene of the unsolved Peterson murders that have haunted him for decades. As the past and present collide, Elias realizes the disappearance is no coincidence. Someone is watching. Someone has been waiting. And the truth buried beneath centuries of secrecy may be far more dangerous than any killer he has ever faced.
To find the missing scholar, Elias must confront his greatest failure, unravel an ancient conspiracy, and solve the mystery that nearly destroyed him. Because some cases are never truly closed. And some secrets were buried for a reason.
