Kinda'ichi, Miyuki, and Kenmochi return to the island Opera House Hotel for the third time (the second was detailed in the first of a series of Kinda'ichi novels by Seimaru Amagi), this time after the death of the hotel's owner, Kurosawa. The hotel and island has been bought by an old friend of Kurosawa, who wishes to honor his memory with a final performance of The Phantom of the Opera, before tearing the place down for good. Along with Kinda'ichi and gang, the new owner has invited members of Kurosawa's old theatre troupe. However, tragedy strikes again when murders occur before the performance can take place.
