Okay so let's talk about how this mystery is structured because the author really knows how to build tension without ever feeling like they're pulling your leg.
We open with a crime scene — bones under a stove, six to seven years old, in a building with high resident turnover. Classic setup. But then the author layers in so many threads that by the time we reach the nursery rhyme reveal, everything clicks into place in the most satisfying way.
The first thread: Auntie Wang's gossip about Xiao Wei, the gentle young man who disappeared. We get his girlfriend — heavy makeup, changed hair color constantly, acted superior — and we get the sense that something was off about their relationship. The second thread: the yellowed paper with faded numbers embedded in the cement. 'One, two, three...' and then nothing legible. The third thread: the metal pad under the flowerpot on the balcony, corroded beyond useful prints but clearly placed there deliberately.
And then the child. Just a kid playing hide-and-seek, humming that rhyme, completely unaware that her game is solving a six-year-old murder mystery. 'Four, five, six, can't be found. Seven, eight, nine...' and suddenly the illegible scrawl on the paper rearranges itself in Li Heng's mind. The deceased, curled up in cement, trapped in an eternal game of hide-and-seek. 'Caught you now.'
What I love about this reveal is that it doesn't feel manufactured. The author planted all the pieces — the numbers on the paper, the child's voice, the game of hide-and-seek — and then let them converge naturally. No deus ex machina. Just a kid being a kid and a detective sharp enough to connect the dots.
The pacing is also worth praising. These seven chapters move at a clip but never feel rushed. Every scene advances the investigation or deepens our understanding of Li Heng. I couldn't put it down and I'm already counting the hours until the next batch.
