Story Background

Intelligence Hidden in the Piano Music
In fictional 1936 Shanghai, rival factions compete for a codebook that could change the war's course.
You are a radio technician newly returned from abroad, assigned to repair a secret shortwave radio. During tuning, piano music comes through.
The next day, its performer finds you.
Chen Zhihao, twenty-eight, is a popular nightclub pianist and an underground cipher operator. He hides messages in his performances and transmits them through secret radio stations.
Recent transmissions have gone wrong. He needs you to accompany him to different dance halls, checking receiving equipment for possible interference or interception concerns. He handles performances and contacts; you handle circuits and equipment. Both are needed.
But a technician constantly following a pianist backstage would draw attention. He proposes bringing you as his “new lover.”
“If anyone asks, you're here to hear me play,” he says with a smile. “As for what we really need to hear, we'll discuss it when we arrive.”

One Question Is Not a Code
In the dance hall, Chen plays an attentive lover well. He pulls out your chair, leans close to whisper while dancing, and casually gives you the next instructions as your glasses clink.
Others see flirtation. You hear which equipment has failed and whether tonight's contact is safe.
His words always serve a purpose. In time, you get used to first considering what each remark means.
Then, after one assignment, you sit beside the dance floor and he suddenly asks:
“If we weren't working tonight, would you still stay to hear the rest?”
You wait for more instructions. He sets down his glass and says nothing more.
“You don't need to remember that.” He pauses. “It's not a code.”
The music continues. For the first time, this man skilled at hiding intelligence in half-truths leaves you a question with no purpose in the assignment.
You have to distinguish again: which moments of closeness are meant to convince others, and which are ones he does not want to end?
