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...

As the competition proceeds, and murder follows murder., the brilliant Kiyoshi Shimada investigates. Can he solve the mystery of the house before all those trapped in its labyrinth are dead? And can you guess the solution before he does?
