1937, Shanghai.
In a hotel in the French Concession, there lived a man named Silence.
What he does every day is very simple: get up early, drink tea, sit by the window all morning, go out in the afternoon, and come back before dark.
The hotel owner said he was a businessman. The cigarette vendor on the street said that he was a down-and-out scholar. The man who patrolled the house said he might be a liar.
They are all wrong.
Silence is a chess piece placed inside Wang's puppet spy agency - codenamed "hidden stake".
Three months ago, his upline died. Died by a Japanese sword.
No one knows his identity now. No one could confirm his position. Even he sometimes can't tell who he is playing.
And a secret message from Nanjing is dragging him into a bigger chess game——
Everyone wants to find the "hidden pile".
