Scrap of Paper: Four Years

Four years ago, an "intelligence error" killed thirty-seven of our own people. Lu Zheng's brother died inside. He applied to be transferred to the Intelligence Analysis Service and waited for a year—for a chance to get that name. Then he received a small practice case: duplicate keys, encryption errors, and the signal source pointed to a military hospital. When he found her, he didn't know that she was also waiting for him. She was forced. Killed by his younger brother. Invisible thread. She left a flaw - it wasn't a mistake, it was the only choice she could make. Two people, each hiding in the darkness, recognized each other in the corridor.
