Shen Huaizhou's psychic ability came from the fire in his childhood.
Now he is a police consultant, reading memory fragments by touching evidence.
When a bloody baby tooth is hidden in the stitches of a missing girl's rag doll, he sees the killer humming a gardenia-scented nursery rhyme.
The copper whistle clenched tightly by the charred corpse of the arsonist sounded the fire alarm in the orphanage thirty years ago.
The negative comments on the screen of the victim in an online violence case actually came from her deceased mother's IP.
Every piece of evidence points to the same small green brick courtyard.
As for the century-old gardenia in the courtyard, the memory of Shen Huaizhou's disappearance is buried deep in its roots.
