Famous London detective Alfred Hawthorne never imagined he would be at the center of one of London's most dangerous cases. When the bride died mysteriously at the bloody wedding, leaving only a white feather on the scene, a deadly game that spanned ten years quietly began. The sapphire in the museum mysteriously disappears, Jack the Ripper reappears in London, and the ghost ship returns carrying innocent souls... Each case points to a mysterious organization called "White Dove", as well as Hawthorne's own broken childhood memories.
As the investigation deepens, Hawthorne discovers that all the dead have one thing in common - they are all related to the dark past of St. Mary's Orphanage. What's even more frightening is that every murder scene contains codes that only he can crack. When the final clue leads to the basement of the orphanage, a truth that subverts his cognition awaits him: Did he solve the mystery, or is he himself part of the mystery?
When the detective becomes the key puzzle piece of the murder case, and when the pursuer finds his hands covered with blood, this trial in the name of justice will eventually end with the judge himself.
