The Sea as a Barrier

The Physical and Psychological Barrier
The Isolation
The sea cut off the island from the mainland. It was a physical barrier that prevented escape. The characters were trapped. The sea was also a psychological barrier, separating them from the normal world. They were in a limbo, a place where the rules of society no longer applied.
The Sea as a Reminder
For Vera Elizabeth Claythorne, the sea was a constant reminder of her crime. She had drowned Cyril in the sea. The sound of the waves, the smell of salt—it all brought back the memory. The sea was a character in her mind, a witness to her guilt.
The Sea as a Grave

The Final Resting Place
Armstrong's Body
Dr. Edward George Armstrong's body was washed ashore. The sea gave him back. The sea was a tomb for the victims. It also offered a chance for the truth to emerge. The sea delivered the confession bottle, finally revealing the mystery.
The Sea's Impartiality
The sea is impartial. It does not judge. It simply is. The characters' fates were determined by the sea's whims. The sea was a neutral force, but it also symbolized the inevitability of death. The island was a place where the sea ruled, and the sea was patient.
