〈STORY〉
There had been a string of murder cases in which bodies were discovered along the riverbank.
None of the cases had been solved. The police believed they were a series of murders committed by a single perpetrator—commonly known as the “Riverside Killer.”
Amid this situation, a new body was discovered in the middle of a party being held at a riverside restaurant.
Despite the large number of people present, no solid leads pointing to the culprit were found.
To uncover the truth behind the case, the police decided to gather those involved at the scene once again to question them…
Why Are the Bodies Found by the River?
Why do they have to be found by the river, of all places?
Faced with a baffling series of murders, journalist Takao Kurohane’s mind springs into action.
