A number of influential South Korean nationals are committing suicide on UK soil. In all cases they seem to simply drop whatever they're doing and swiftly -- almost vacantly -- end their own lives. An electronics importer falls from the top floor of his high-rise office, the ambassador to the UK shoots his chauffeur and drives his own car off London Bridge, an actor sets fire to himself during a movie premiere...

August and Toby investigate and slowly uncover the ancient force of the Rain-Soaked Bride, a ghostly spirit of vengeance that drags her enemies to their deaths.

Once summoned the spirit cannot be dismissed until it takes the life it is charged with, it will be unstoppable in its pursuit of the mortal it has in its sights. Unfortunately, after getting too close to the source of the spirit, that mortal is now Toby Greene.
