The world of tech-crime detective Chen Mo fell apart when his girlfriend, Lin Wei, mysteriously vanished beneath the surveillance cameras of a subway station. The authorities concluded that she had left of her own accord, but Chen Mo’s keen eyes spotted the one flaw in the seemingly perfect footage: an inexplicable gap of thirteen seconds. Defying regulations, he pursued the case alone. His leads pointed to a tech giant contracted to work on the subway project and its bizarre “extra” cameras. But the closer he got to the truth, the deadlier the warnings from the shadows became. One anonymous text arrived on his phone: “Stop looking at things you’re not supposed to see.” With an enemy’s eyes potentially hidden in every corner of the city, Chen Mo must race against a terrifying, invisible opponent through the blind spots of an all-seeing surveillance network and uncover a kidnapping plot woven from flawless technology.
