Chen Mo was once a rising star in the provincial department’s behavioral analysis unit. After a “major misjudgment,” he was demoted to an archives clerk, and his bloodstained past shut his powers of observation away like a steel gate. Then a mysterious Reversal Hourglass appeared. It could let him glimpse fragments of the truth behind cases, but it also dragged him into a deadly labyrinth. Every profile was a battle against the abyss of human nature, and every reversal of time exacted a mental toll. As Chen Mo solves a series of baffling cases, he must break free of the shadow of his “misjudgment” and master the hourglass’s power. At the boundary between crime and truth, he must awaken once more his “sealed eyes,” capable of seeing into the human heart.
