The Curse of 13 is the first novel of Shinzo Mitsuda's Detective of the Omens of Death series.
Our 20 years old Detective of the Omens of Death had just opened business in Tokyo. When the Detective was a child, his ability to see the Omens of Death from other people made him a freak in the eyes of almost everyone around him, and the young man was still trying to deal with this strange and gloomy psychic ability, and living as normal a life as he could.
His first client is a young woman who was engaged with a successful businessman, but her boyfriend (despite of his young age) suddenly died due to a heart attack at the eve of their wedding. When the Detective uses his ability to 'look at' the young woman and members of boyfriend's family, he can see the shadows/omens of death clinging to each of their bodies like many many twisting, large, dark earthworms.
If the Detective failed to solve the mystery of the Curse of 13, his client and the other family members were all doomed to die one by one. But why would any one want to curse these people? How can the Curse be broken?
This book is a nice series-opener, the setting and the character design is refreshing, the 'murder mystery' is griping and well planned, the creepy atmosphere within the mansion where the young woman and her boyfriend's family live is masterfully crafted, the ending is a little bit weak, but it is still an entertaining read.
