Miyagaki Yotaro is one of Japan’s most famed mystery writers, but several years ago he put down his pen and left the Tokyo literary world for a life of seclusion in the remote Labyrinth House, built by the notorious architect Nakamura Seiji. When four of the country’s most exciting up-and-coming crime writers are invited to the house for Yotaro’s birthday party, they are honoured to accept. But no sooner have they arrived than they are confronted with a shocking death, then lured into a bizarre, deadly competition with each other.
