August 11th

August 11th is the day on which the hidden architect of the Indian Island murders, Lawrence John Wargrave, shifts from covert poisoner to active stage-manager, engineering the deaths of the last four victims in a single night and ensuring that the island's mystery would appear insoluble. By dawn of August 11th, three people remain alive on the island: Vera Claythorne, Philip Lombard, and William Henry Blore. Dr. Armstrong has vanished during the night, and the three survivors, after a frantic search, conclude that he must be the murderer hiding somewhere on the rock. The discovery of Armstrong's drowned body, washed up between rocks and later dragged above the high-water mark, confirms that someone else—someone who was not Armstrong—is still alive and orchestrating events. That someone is Wargrave, who has been playing dead since the evening of August 10th, when he staged his own murder in the drawing-room, robed in a scarlet curtain and grey wool, with a simulated bullet wound on his forehead.

The Final Deceptions and the Death of Blore

On the morning of August 11th, the three survivors—Vera, Lombard, and Blore—spend the daylight hours on the cliffs, flashing a mirror at the mainland in the hope of signaling for rescue. The sea remains too rough for any boat to approach. As the afternoon wears on, Blore, confident in his physical strength and police training, decides to go up to the house alone to fetch food. Wargrave, watching from a window, seizes the opportunity. He drops a heavy marble bear-shaped clock from Vera's bedroom window onto Blore's head, crushing his skull instantly. The murder follows the nursery rhyme's eighth verse: "A big bear hugged one and then there were two." Vera and Lombard, hearing the thud from the cliffs, rush up to find Blore's body spread-eagled on the terrace.

The Confrontation and Vera's Shot

Now alone on the island, Vera and Lombard face each other with the full knowledge that one of them must be the killer. Lombard, who has recovered his revolver—secretly returned to his drawer by Wargrave—is openly suspicious of Vera. She, in turn, has come to believe that Lombard is the madman. They walk down to the shore, where they discover Armstrong's body wedged between rocks. While pretending to help Lombard drag the corpse above the tide line, Vera deftly picks his pocket and seizes the revolver. When Lombard realizes what has happened, he springs at her; she shoots him through the heart. The relief that floods through Vera is immense: she is alone on the island, the nightmare over. She walks back to the house, carrying a single china Indian boy from the dining-room, and climbs the stairs to her bedroom.

The Final Verse and Vera's Hanging

In Vera's bedroom, Wargrave has prepared the final scene. A rope with a noose hangs from a hook in the ceiling, and a chair stands beneath it. The room smells of the sea—the same smell that haunted her memories of Cornwall, where she had allowed Cyril Hamilton to drown. Overcome by exhaustion, guilt, and the hypnotic power of the nursery rhyme, Vera mounts the chair, adjusts the noose around her neck, and kicks it away. She hangs herself, completing the rhyme's last line: "He went and hanged himself and then there were none." Wargrave, who has been hiding in the wardrobe, steps out. He rights the chair against the wall, picks up the revolver from the top of the stairs where Vera dropped it, and carefully preserves her fingerprints on it.

The Aftermath and the Confession

With all ten victims dead, Wargrave returns to his own room. He writes a full confession, seals it in a bottle, and casts it into the sea. Then he arranges his own suicide: lying on his bed, he places his eyeglasses beneath his body, loops an elastic cord from the glasses around the door-handle, and attaches the other end to the revolver. He presses the trigger with a handkerchief-protected hand, shooting himself through the forehead. The elastic recoil pulls the revolver to the door, where it detaches and falls to the floor, leaving no trace of the mechanism. When the rescue party arrives on August 12th, they find ten dead bodies and no living soul on the island. The police investigation, despite exhaustive efforts, cannot solve the mystery until Wargrave's confession is recovered from the sea. August 11th thus stands as the day when the murderer's grand design reached its perfect, terrible conclusion—a day of deception, violence, and psychological manipulation that left no witness and no explanation but the one the killer himself chose to provide.
