Moonlight Bunnies of Death. The Tragedy of 1988

The volcano is falling asleep. The killer wakes up…

A group of students, including four members of the Detective Study Club from Kyoto, sets up camp on the dormant volcano Yabukiyama. Under the beautiful full moon, they talk by the campfire and play a murder mystery game, randomly choosing who will be the killer and who the victim. It seems like a friendship that will last a lifetime is forming. But the idyll turns into a nightmare…
The volcano awakens, an eruption blocks the way down: they are cut off from the world. And at that moment, one of them is really killed. The letter Y is found on the ground next to the body. What is it? The killer's signature? Or a dying message from the victim pointing to them? In an atmosphere of creepy mystery, the world of friendship and carefree joy collapses, giving way to suspicion, fear, and a desperate search for the truth…
This victim will not be the only one. The author, in the best traditions of honkaku, challenges the reader: you know exactly as much as the one who solves the deadly puzzle; will you be able to do it yourself?
