When an archivist in the small coastal town of Lantau was sorting out an old case file that was about to be destroyed, she discovered that there were unexplainable overlaps between the disappearance record of a girl fifteen years ago and a seemingly ordinary seaside drowning case. When she tried to track down the truth, she gradually uncovered the silence that a group of people had maintained for fifteen years. Behind the silence, there was no one person's crime.
- A "disappearance case" and "drowning case" spanning fifteen years were reconnected by an old file
- The relationships between the deceased, the missing, witnesses, and law enforcers are constantly inverted, and the readers' perceptions of "victims" and "perpetrators" are repeatedly reconstructed
- The truth is not a single point of reversal, but is composed of multiple layers of concealment, institutional gaps, family secrets and human self-preservation.
