Tong Xian is a psychological patient with an exceptionally strong sense of empathy and a remarkable ability to feel as if he is experiencing things firsthand.
To clear his aunt of suspicion in a murder case involving a student caught up in a family dispute, he sets out to search for the truth.
He never expected that the trouble would end up pointing back at him, too.
When the psychological consultant tests him, he reveals almost none of the full story.
He develops a new theory.
The case seems closely linked to shared psychotic disorder.
A rare, out-of-print journal he acquired by chance becomes a crucial clue.
