Crypt of the Capitol

A brilliant scholar betrayed. A deadly game unleashed on the nation's capital. When three United States senators destroy his career and suppress his life's work, disgraced Egyptology scholar Donald Sloan vows a chilling vengeance. Armed with ancient poisons and lethal intellect, Sloan assassinates his targets before launching an audacious nationwide puzzle: one hundred historical ciphers sent directly to The Washington Post, each revealing a new piece of a sinister conspiracy.
FBI Special Agent Laura Minton is tasked with stopping the mastermind before he executes his final strike. Recognizing that the killer's motives are rooted in antiquity, Minton enlists renowned Smithsonian epigrapher Howard Pender to crack the daily codes. Together, they must navigate a labyrinth of ancient metaphors, government corruption, and ticking twenty-four-hour deadlines. As the stakes rise and surviving politicians scramble to bury their secrets, Minton and Pender realize the game is far deadlier than they imagined.
Every cracked clue brings them closer to the truth-and directly into the crosshairs of an ideological reckoning. Can they solve the final cipher before American democracy pays the ultimate price?
