Kosuke Kindaichi arrives on the remote Gokumon Island bearing tragic news - the son of one of the island's most important families has died, on a troop transport ship bringing him back home after the Second World War. But Kindaichi has not come merely as a messenger - with his last words, the dying man warned that his three step-sisters' lives would now be in danger. The scruffy detective is determined to get to the bottom of this mysterious prophesy, and to protect the three women if he can.
As Kosuke Kindaichi attempts to unravel the island's secrets, a series of gruesome murders begins. He investigates, but soon finds himself in mortal danger from both the unknown killer and the clannish locals, who resent this outsider meddling in their affairs. Loosely inspired by Agatha Christie's And Then There Were None, the fiendish Death on Gokumon Island is perhaps the most highly regarded of all the great Seishi Yokomizo's classic Japanese mysteries.
