Jiang Xiaoba is so popular with his father that this private detective only knows how to find people.
When he officially took on the first missing person case, he unfortunately ran into his happy enemy Zuo Yi.
Zuo Yi is also a new detective. He suffered a tragedy since he was a child and has many secrets hidden in him. By chance, he becomes his father's apprentice.
So Jiang Xiaoba, Zuo Yi and their father embarked on a journey to find the missing person.
All their missing persons cases are recorded in the book. This is a missing persons apocalypse, telling the warmth and coldness of the world, the joys and sorrows of human nature.
This is not a suspenseful detective novel, I would rather define it as a tender and healing novel.
