The Codex is a 2003 thriller novel published by Tor Books. It is the first solo fiction novel by Douglas Preston and introduces the character of Tom Broadbent.
"Greetings from the dead," declares Maxwell Broadbent on the videotape he left behind after his mysterious disappearance. A notorious treasure hunter and tomb robber, Broadbent accumulated over a half a billion dollars' worth of priceless art, gems, and artifacts before vanishing—along with his entire collection—from his mansion in New Mexico.
At first, robbery is suspected, but the truth proves far stranger: As a final challenge to his three sons, Broadbent has buried himself and his treasure somewhere in the world, hidden away like an ancient Egyptian pharaoh. If the sons wish to claim their fabulous inheritance, they must find their father's carefully concealed tomb.
The race is on, but the three brothers are not the only ones competing for the treasure. This secret is so astounding it cannot be kept quiet for long. With half a billion dollars at stake, as well as an ancient Mayan codex that may hold a cure for cancer and other deadly diseases, others soon join the hunt—and some of them will stop at nothing to claim the grave goods.-Publisher's synopsis
