While not my favorite of the Kosuke Kindaichi mysteries I‘ve read, there is still a lot to like about this one. Fulfilling the last request of a dying friend, Kosuke travels to Gokumon island in a, he soon discovers, futile attempt to prevent a series of murders. Discovering the reason behind the macabre murders, as well as the perpetrator behind them, will take all of Kosuke‘s ingenuity. Atmospheric and more entertaining than not.
