In Shanghai in 1940, the lights were like daylight and the undercurrent was turbulent.
On the surface, Shen Yanqiu is the confidential secretary of Wang Puppet Intelligence Department. He is calm, taciturn, cautious and low-key; but secretly, he has been lurking for many years, codenamed "Guiyan". During a routine contact, a murder occurred at the train station - the liaison officer died on the spot, leaving only half a theater ticket and an unfinished sentence.
From that moment on, everything started to go sideways.
Theater contacts, incomplete lists, intelligence lines that have been repeatedly tampered with... Shen Yanqiu gradually discovered that this was not a single leak, but a "screening network" that had already been laid out. What shocked him even more was that the codes that only belonged to his old partner Gu Xingzhou appeared again.
Will the dead really come back?
